What is

Sintered Neodymium?

Neodymium magnets are the most widely used magnetic materials available today.The processing of sintered NdFeB magnet is powder metallurgy. Due to its high Remanence, Coercivity, energy product, small size, light weight, and other special characteristics, the sintered NdFeB magnet can be widely used besides in electro-acoustic components, medical devices,  sensors, magnetic separator, magnetic catche, etc. Furthermore, automotive parts, computer hard drives, wind power, power tools, electric  bicycles, air conditioning compressor, elevator, aerospace and other fields.All the NdFeB products that sold by Ideal Magnet Solutions Inc have been authorized a patent license by the original patent holder, and they can  be sold to European and North American market legally.
