2. Neodymium magnets are mainly made from neodymium ,iron, and boron. It is the ideal magnetic material in the world till now and have been used universally in the world . It has super strong magnetic force and high intrinsic coercive force and after concocting , it can stand very high working temperature, as high as 200 centigrade.
3.Features:
The most powerful permanent magnet, offers a great return for cost & performance, have the highest field/surface strength(Br), high coercivity(Hc), can be easily formed into various shapes and sizes. Be reactive with moisture and oxygen,usualy supplied by plating (Nickel, Zinc, Passivatation, Epoxy coating, etc.).
