Neodymium Iron Boron (NdFeB) magnets are alloys of the Lanthanide group of elements. Rare Earth magnets are the most advanced commercialized permanent magnet materials today.
Relying on strong technology and advanced production facilities, we can manufacture sintered NdFeB magnets in all grades and specifications, such as N35-N52, N35M-N50M, N35H-N48H, N30SH-N45SH, N30UH-N42UH, N30EH-N40EH, N30AH-N33AH or any other customer specified grades with high coercivity, low reversible temperature coefficients and low weight loss. We can manufacture NdFeB products with low weight loss through continuous creation. Under the HAST condition of two atmospheric pressure,120 C and 100% humidity, its weight loss in 192 hours is less than 5mg/cm2. So it can meet requirement of motor and other high-end field.
