Product Name: NdFeB Magnet Ring
NdFeB magnet is a alloy magnet of neodymium, iron, boron and other trace metal element. It is the strongest rare-earth permanent magnet, with high energy and good coercivity. .The third generation of NdFeB is the strongest magnets in the permanent magnet, it not only has high remanence, high coercivity, high energy product, high characteristics, and easily processed into various sizes, has been widely used in aviation, aerospace, electronics, electro-acoustic, mechanical and electrical products, instruments, meters, medical technology and other devices which required the permanent magnetic field, especially suitable for the development of high-performance, small size, light products.
