neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available. They have replaced other types of magnets in the many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners.
Magnet manufacture process can be divided to sintering, casting and injection molding generally. Each element will have influence on final magnetic materials, such as our new technical breakthrough for alnico KM500 to KM600, titanium element is amazing to increase the resistance of magnetic loss with change parameter for Hcj, related Hcb as well, our technical team is working on a video to illustrate each process in manufacturing, which will be coming soon!
