Bonded Neodymium Magnets (also known as injection molded magnets) are made from a combination of Neodymium Magnet powder and a binder. They are used in various applications and are available in various sizes, grades, shapes, and coatings to meet the needs of different industries. The most common size of the bonded neodymium magnet is 8 poles, and the most common grades are BN-4, BN-6, BN-8, BN-10, and BN-12L. Available shapes include discs, blocks, cylinders, rings, and more. The maximum operating temperature for these injection bonded magnets is typically between 120°C and 150°C. They can be coated with epoxy, nickel, parylene, and other coatings.

When it comes to shipping of bonded neodymium magnets, it is important to ensure that the magnets are packaged properly to avoid any damage. The packaging should be able to protect the magnets from moisture, dust, dirt, and other external factors that could affect its performance.
The magnet should be wrapped in a plastic bag and then be placed in a cardboard box. The box should be lined with foam to provide additional protection from any potential shocks or impacts during transit. It is also important to label the box clearly with the type of magnet inside it so that it is easy to identify when it arrives.
The bonded neodymium magnet should also be shipped with a return address and contact information in case of any issues during transit. This will help ensure that the customer can easily contact the company in case of any problems.
In conclusion, proper packaging and shipping of bonded neodymium magnets is essential to ensure that they arrive in perfect condition and that the customer is satisfied with the product.
