Bonded Neodymium Magnet |
Bonded neodymium magnets, also known as bonded neo-magnets, are a type of permanent magnet made with neodymium, iron, and boron. They are manufactured using a pressing and sintering process and then bonded with a composite material. Thanks to their high coercivity, high remanence and low coercivity, bonded neodymium magnets are highly reliable and durable. They are available in various shapes such as disc, block, cylinder, ring, etc. and sizes that can be customized according to your requirements. The maximum operating temperature of these magnets is between 120°C-150°C and they can be magnetized in axial, radial or multi-poles direction. Bonded neodymium magnets are packed safely in carton boxes and pallets to make sure they reach you in perfect condition.
