Product description

High quality NdFeB magnets is classified into two types, bonded NdFeB magnets and sintered NdFeB magnets. Bonding NdFeB magnet is actually injection molding, while sintered NdFeB magnet is a thermoforming process by vacuum pumping. NdFeB magnet is the superstrong permanent magnet so far. It is available for grades N35-N52, and can be made into various shapes as required: circular, square, perforated, segment, bar, convex and trapezoid etc. Despite of these strong points, its surface is subject to rusting. Therefore, the magnet generally requires for protective surface treatment: nickel plating, galvanizing, gold plating and epoxy resin coating. The applicable ambient temperature of ordinary NdFeB magnet is below 80 ℃, but there are some types of NdFeB magnets resistant to high temperature over 200 ℃.  This type of magnet is mainly used in electronic, electrical, packaging, motor, toy, leather and automobile machinery industries.
