Ndfeb Magnets Have Broad Prospects For Development

NdFeB magnets can be divided into bonded NdFeB and sintered NdFeB. Bonding is injection molding, while sintering is formed by vacuum and high-temperature heating. NdFeB magnets are permanent magnets with the strongest magnetic force so far at room temperature (second only to holmium magnets at absolute zero, but far stronger than all known permanent magnets at room temperature). The material is 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 easy to rust, so some protective surface treatments are usually needed: nickel plating, zinc plating, gold plating, epoxy resin plating, etc. The applicable ambient temperature of ordinary NdFeB magnets is below 80 degrees and Curie temperature is 320-380 degrees. Mainly used in electronics, electrical appliances, packaging, motors, toys, leather, automotive machinery and so on.

Market value: The core technology of NdFeB magnets industry is mainly embodied in the manufacturing process, specifically in the uniformity, consistency, processing quality, coating quality and so on.

It is expected that there will be no alternative magnetic materials to NdFeB magnets in the next 20 years. The main materials for producing NdFeB magnets are rare earth metal Nd, Pr, Holmium, common metal Fe, Al, ferroboron alloy and other rare earth materials.
