NdFeB magnets can be divided into two types: bonded NdFeB and sintered NdFeB. Bonding is actually injection molding, while sintering is vacuuming and heating at high temperatures. NdFeB magnets are by far the most powerful permanent magnets at room temperature (second only to holmium magnets at absolute zero, but far stronger than all known permanent magnets at room temperature). Material grades are N35-N52; Various shapes can be processed according to specific requirements: round, square, punching, magnetic tile, magnetic rod, convex, trapezoidal, etc.; Despite these advantages, the surface is prone to rust, so it is usually necessary to do some protective surface treatment: nickel plating, zinc plating, gold plating, epoxy plating, etc. The applicable ambient temperature of ordinary NdFeB magnets is below 80 degrees, and the Curie temperature is 320~380 °C. It is mainly used in electronics, electrical appliances, packaging, motors, toys, leather goods, automotive machinery, etc.
