Neodymium Iron Boron (NdFeB) is another type of rare earth magnetic material. This material has similar properties as the Samarium Cobalt except that it is more easily oxidized and generally doesn’t have the same temperature resistance. NdFeB magnets also have the highest energy products approaching 50MGOe. These materials are costly and are generally used in very selective applications due to the cost. Cost is also driven by existing intellectual property rights of the developers of this type of magnet. Their high energy products lend themselves to compact designs that result in innovative applications and lower manufacturing costs. NdFeB magnets are highly corrosive. Surface treatments have been developed that allow them to be used in most applications. These treatments include gold, nickel, zinc and tin plating and epoxy resin coating. magnet paraphrase

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.  cylinder neodymium magnets  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.
