Shipping neodymium magnets via air requires special considerations due to their strong magnetic fields. As a neodymium magnet manufacturer, we understand that these magnets, being some of the most powerful permanent magnets, are subject to strict regulations to ensure safe and compliant transportation. Here is a comprehensive guide to shipping neodymium magnets by air:   Classification of Neodymium Magnets and The Strength Neodymium magnets are considered hazardous materials by both the International Air Transport Association (IATA) and the Department of Transportation (DOT) if they exceed certain magnetic field thresholds. Small Magnets: Smaller neodymium magnets, such as those used in consumer products, may not be subject to dangerous goods regulations, but it is crucial to check their field strength. High strength neodymium magnets: Neodymium magnets with a magnetic field strength that exceeds 0.005 Gauss at a distance of 2.1 meters from the package must be treated as Class 9 (Miscellaneous Dangerous Goods) for air transport under IATA and DOT regulations.   Accurately measuring magnetic field strength Accurately measuring magnetic field strength is crucial to ensure your magnetic products meet air shipment requirements. To ensure compliance, we suggest using a gaussmeter and adhering to the following procedure: Select a gaussmeter with a resolution of 0.1 mG or higher for accurate readings. Move the probe around the package to identify the point of maximum magnetic field strength. Measurements should be taken at a distance of 7 feet (approximately 2.1 meters) from the container's walls. If the magnetic field strength exceeds the permitted limit, additional shielding or other mitigation methods will be necessary to meet air transport standards.
 By following this measurement process, you can verify that the magnetic product's field strength is within the allowed limits, preventing potential shipment issues caused by exceeding the limits.   Packaging Requirements Proper packaging is essential for safely shipping neodymium magnets. Here are the key considerations: Shielding the Magnetic Field: The package must be designed to shield the magnetic field to prevent interference with aircraft systems and nearby devices. Special magnetic shielding materials may be required, like iron or steel, to create a magnetic shield. Stabilizing the Magnet: Magnets should be secured inside the packaging to prevent movement, which could cause magnetization or damage to the magnet itself. Padding and Protection: The packaging should include padding to protect the magnet from physical shock and avoid any movement inside the box.   Shipping Restrictions and Airline Requirements Airline Restrictions: Different airlines may impose varying restrictions for shipping neodymium magnets. It’s important to confirm with the airline or freight forwarder about their specific requirements. Packaging Compliance: Ensure the packaging complies with the airline’s regulations regarding the maximum permissible magnetic field strength, and that all necessary labels and documentation are in place.   Safety Considerations Electronic Equipment: Ensure that magnets are kept away from sensitive electronics, including devices like mobile phones, laptops, medical equipment, and navigation systems, both during packaging and transport. Training: Staff handling the magnets must be trained in the proper handling of hazardous materials to ensure compliance with shipping regulations.   By following these guidelines and ensuring compliance with the necessary regulations, you can safely and efficiently ship neodymium magnets by air. Shipping magnets by air presents its own set of challenges, Zoyn, with over 25 years of experience in custom neodymium magnets, can assist in selecting the right packaging materials to ensure both safety and compliance during air transport. Our general approach is to transport all magnetized products via ground services. However, when air transport is required, we can prepare the magnets with adequate shielding to ensure safe and compliant shipping.

In the world of magnetism, neodymium magnets have emerged as a game - changing force. Their unique properties have made them a popular choice across a wide range of industries. But what exactly makes neodymium magnets stand out from other magnetic materials?   Exceptional Magnetic Strength Neodymium magnets are renowned for their incredibly high remanence. Remanence refers to the magnetic field remaining in a magnet after the external magnetic field used to magnetize it is removed. N52 grade neodymium magnets, one of the strongest grades available, can have remanence values as high as 1.4 teslas. To put this into perspective, ferrite magnets, a common alternative, typically have remanence in the range of 0.2 - 0.4 teslas. This high remanence allows neodymium magnets to generate a much stronger magnetic pull, making them ideal for applications where a powerful magnetic force is required, such as in electric motors used in hybrid cars or in high - performance speakers.   Another aspect of their strength is high coercivity. Coercivity is the measure of a magnet's ability to resist demagnetization. Neodymium magnets have a very high coercivity, which means they can maintain their magnetic properties even when exposed to strong external magnetic fields or high temperatures (to a certain extent). In comparison, alnico magnets, which are known for their good temperature stability, have lower coercivity values in some cases. This makes neodymium magnets more reliable in applications where there may be a risk of accidental demagnetization.   Power - to - Size Ratio One of the most significant advantages of neodymium magnets is their remarkable power - to - size ratio. Due to their high magnetic strength, small neodymium magnets can deliver a substantial magnetic force while being relatively small in size. This is a huge benefit in applications where space is at a premium, such as in portable electronics like smartphones, tablets, and wireless earbuds. In these devices, small neodymium magnets are used in components like vibration motors and speakers, providing the necessary magnetic functionality without taking up too much space.   Ease of Integration Their lightweight nature also makes them easier to integrate into various products. When compared to larger and heavier magnetic materials, neodymium magnets allow for more flexible design options. For example, in the aerospace industry, where weight reduction is crucial for fuel efficiency, neodymium magnets can be used in actuators and sensors without adding excessive weight to the aircraft.   Diverse Industrial Uses Neodymium magnets find applications in a vast array of industries. In the medical field, they are used in MRI machines to generate the strong magnetic fields required for imaging. Their precision and strength enable detailed and accurate scans. In the manufacturing industry, circular strong neodymium magnets are used in magnetic separators to remove metal contaminants from materials. In the renewable energy sector, neodymium magnets are a key component in wind turbine generators, helping to convert wind energy into electricity efficiently.   Consumer Product Applications In consumer products, neodymium magnets are everywhere. They are used in magnetic closures for bags and wallets, providing a convenient and secure way to fasten. In toys, they can create interactive and engaging play experiences. Their versatility stems from their ability to be shaped, sized, and magnetized in different ways to suit specific application requirements.   Neodymium magnets' exceptional magnetic strength, compact size, and versatility set them apart from other magnetic materials, making them an invaluable resource in modern technology and industry.

Bonded neodymium arc magnets, is one of the main products sold by Zhejiang Zoyn Magnetics Co., Ltd. It has become a popular choice in various design applications due to its unique performance advantages. These magnets, crafted from a combination of neodymium, iron, and boron (NdFeB) powders mixed with a binding agent, offer distinct benefits that enhance the functionality and efficiency of numerous products.   Precision in Magnetic Field Distribution In applications like magnetic sensors used in automotive ABS (Anti - lock Braking Systems), precision in magnetic field distribution is crucial. Bonded neodymium arc magnets can be designed with great accuracy to produce a specific magnetic field pattern. Their arc shape allows for a more targeted and concentrated magnetic field in a particular direction. For example, in a sensor that detects the rotation of a wheel, the arc magnet can be shaped in such a way that it provides a consistent and reliable magnetic signal as the wheel turns. This precision ensures that the sensor can accurately measure the wheel's speed, enabling the ABS system to function effectively and prevent wheel lock - up during braking.   Design Flexibility One of the most significant advantages of arc bonded neodymium magnet is their design flexibility. They can be molded into complex shapes, which is highly beneficial in compact electronic devices. Consider the design of a wireless earbud. The limited space inside the earbud requires magnets that can fit snugly while still providing the necessary magnetic force for functions like speaker operation and charging. Bonded neodymium arc magnets can be customized to fit the unique curved shape of the earbud housing. This not only optimizes the use of space but also ensures that the magnetic components work efficiently within the small form factor. In addition, the bonding process allows for the integration of magnets with other materials, such as plastics or metals, which can further enhance the overall design of the product.   Cost - Effectiveness in Mass Production For industries involved in mass - producing consumer goods, cost - effectiveness is a major consideration. N52 neodymium half round arc magnets are relatively inexpensive to manufacture compared to some other types of magnets. The use of a binding agent in the production process reduces the amount of raw neodymium material required. For instance, in the production of small toys that incorporate magnetic components for interactive play, the cost savings from using bonded neodymium arc magnets can be substantial. Manufacturers can produce large quantities of these toys without incurring high material costs. Moreover, the ease of molding these magnets into the required shapes simplifies the manufacturing process, further reducing production time and costs.   Resistance to Demagnetization In applications where magnets are exposed to varying environmental conditions, resistance to demagnetization is vital. Bonded neodymium arc magnets exhibit good resistance to demagnetization. Take the example of magnetic closures used in outdoor clothing. These closures need to maintain their magnetic strength even when exposed to moisture, temperature changes, and mechanical stress. Bonded neodymium arc magnets can withstand these harsh conditions and continue to function effectively. Their resistance to demagnetization ensures that the clothing closures remain secure, providing a reliable and long - lasting solution for outdoor enthusiasts.   Bonded neodymium arc magnets offer a range of key advantages in design, from precision in magnetic field distribution and design flexibility to cost - effectiveness in mass production and resistance to demagnetization. These qualities make them an ideal choice for a wide variety of applications, spanning from automotive and electronics to consumer goods and outdoor gear.   If you have more application requirements or questions about magnets products, please contact our professional team.

NdFeB magnets are key products from Zoyn Magnetics, and they are some of the strongest permanent magnets out there, used in many industries. When we talk about NdFeB magnets, two types come up: bonded and sintered. Each has its own traits and uses, so knowing the differences can help you decide what's best for you.   One of the main differences lies in the manufacturing process. Strong sintered NdFeB magnets are made using a powder metallurgy process. The neodymium, iron and boron alloys are first ground into a fine powder. The powder is then pressed under high pressure in a mould to achieve the desired shape. Afterwards, the pressed powder is sintered at high temperatures to fuse the particles together to form a dense and strong magnet. In contrast, bonded NdFeB magnets are made by mixing neodymium powder with a bonding material, such as plastic or rubber. The mixture is then moulded or extruded into the desired shape, resulting in a more homogeneous structure of the magnet due to the even distribution of the binder.   These manufacturing differences can lead to variations in physical properties. Neodymium N52 disc magnet typically have higher magnetic strength. They have higher remanence (the magnetic flux density remaining after the magnetising field is removed) and coercivity (resistance to demagnetisation), making them ideal for applications that require a strong, stable magnetic field, such as electric motors and MRI machines. On the other hand, bonded neodymium magnets have lower magnetic properties. However, they excel in areas such as dimensional accuracy and complex shape forming. Complex shapes and thin-walled parts can be manufactured using bonded materials, which are difficult to achieve with sintered magnets.   Durability and corrosion resistance also differentiate these two types of magnets. Sintered neodymium magnets are susceptible to corrosion due to their porous structure, which is easily penetrated by moisture and other contaminants. As a result, they usually require additional surface treatments such as nickel-copper-nickel plating for protection. Bonded neodymium magnets typically have better inherent corrosion resistance due to the presence of a binder material. The binder encapsulates the neodymium particles, creating a natural environmental barrier that in many cases reduces the need for complex surface protection.   Cost is another important factor. Customized shaped Ndfeb magnets typically involve more complex manufacturing processes and often require additional post-treatment steps for surface preparation, which can drive up costs. Bonded neodymium magnets, which are simpler to manufacture and do not require extensive surface treatment, are often more cost-effective, especially in applications where magnetic strength is not a primary concern.   Both bonded and sintered NdFeB magnets from Zoyn Magnetics have their pros and cons. By understanding their differences, like how they're made, their physical properties, durability, and price, you can pick the right option for your needs, whether in electronics, automotive, or other fields.

Not every industry is chasing cutting-edge tech. Sometimes, what’s really needed is something simple, reliable, and cost-effective. That’s exactly where ferrite magnets shine. They may not have the high-end appeal of neodymium magnets, but they quietly power a huge number of everyday products—and they’ve been doing it for decades.   So, what exactly makes them worth a second look? Let’s break it down.   Affordable Materials, Straightforward Production One of the biggest reasons companies stick with ferrite magnets is cost. They’re made from materials that are pretty easy to find—mainly iron oxide, with some strontium or barium added in. No rare-earth elements, no complicated supply chains, and no unpredictable price swings.   On top of that, the manufacturing process is relatively simple. There’s no need for high-vacuum environments or specialized equipment. That translates to lower production costs, and for industries that need magnets in bulk—think automotive, household appliances, basic electronics—that price difference can really add up.   Tough Enough for Real-World Conditions These magnets might not be the strongest out there, but they’re definitely sturdy. Ferrite ring magnet don’t rust easily, which makes them a solid choice for outdoor use or places where moisture is a factor. They can handle a bit of abuse without losing their shape or strength.   They’re also chemically stable, which means they won’t degrade quickly when exposed to oils, greases, or mild solvents. That’s a big reason why you’ll find them in things like power tools or motor housings—anywhere that durability matters more than raw strength.   High Heat? No Sweat. Temperature changes can be a real issue for certain magnets, especially rare-earth ones that start losing magnetism at relatively low heat. Permanent ferrite magnet, on the other hand, are a lot more stable. They keep working even when things get hot—often up to 250°C or more.   That makes them a good match for products that run warm by design, like electric motors, fan assemblies, or even certain automotive components. When reliability under heat is non-negotiable, ferrites often end up being the safer choice.   Flexible Shapes, Simple Designs Another big plus? Ferrite magnets are super flexible when it comes to shape. Rings, discs, blocks—manufacturers can mold them into whatever form is needed. That gives product designers more freedom to create parts that actually fit the final product, rather than trying to jam in a magnet that doesn’t quite match.   And because they’re ceramic-based, Hard ferrite magnets are easy to machine or press into molds during manufacturing. That keeps tooling costs low and speeds up production times. Win-win.   A Better Choice for the Environment Here’s something that doesn’t always get talked about: the environmental impact. Extracting and processing rare-earth elements is energy-intensive, expensive, and not particularly clean. It’s also tied up with some challenging global supply chains.   Ferrite magnets sidestep all that. They use more common, less harmful materials, and their simpler production process means a smaller carbon footprint. As companies get more serious about sustainability and cleaner sourcing, this is a big plus. For any business trying to align with green initiatives or meet stricter environmental regulations, switching to ferrites can be a step in the right direction.   Real-World Use Cases Still wondering where these magnets show up? They’re literally everywhere. You’ll find them in loudspeakers, refrigerator doors, magnetic tool holders, washing machines, ignition systems, and countless small motors.   Their strength might not break any records, but for holding something closed, aligning components, or keeping a rotating part moving smoothly—they do the job, and they do it reliably.   In factories and workshops, ferrites are often the quiet backbone of the operation. No frills, no drama, just steady performance.   At the end of the day, not every product needs the most powerful magnet on the planet. Sometimes, the smart move is choosing something that works well, lasts long, and keeps costs down. Ferrite magnets check all those boxes.   They might not grab headlines or win awards, but they’re practical, durable, and easy on the budget—and for a lot of industries, that’s exactly what matters most.If you’re a distributor, Permanent Magnets And Magnetic Assemblies provider—talk to us.
