NdFeB magnets can be divided into two kinds of sintered NdFeB and Bonded NdFeB. Actually bonded injection molding, and sintering is heated to high temperatures by vacuum molding! NdFeB magnet is so far the strongest permanent magnet having a magnetic force. Material grades are N35-N52; processing of various shapes according to specific requirements: round, square, drilling, magnetic tile, magnetic, convex, trapezoidal, etc.; In spite of these advantages, but the surface is easy to rust, it usually takes make some protective surface treatment: nickel, zinc, gold-plated, epoxy resin. Common NdFeB magnet applicable environmental temperature is below 80 degrees, but there are also several high temperature of 200 degrees capability. Mainly used in electronics, electrical appliances, packaging, electrical, toys, leather goods, auto mechanics, etc.
