NdFeB magnets are the strongest permanent magnets. Neodymium magnets are magnetic materials with good commercial value. The magnet are used in is diametical magentied. NdFeB magnet are graded according to the magnetism and working temperature. Usually have the range from N35-N52, 33M-50M,33H-48H,30SH-45SH,28UH-40UH,28EH-38EH,30AH and 33 AH.
Main Manufacturing process of ndfeb magnets
1.Pressing ndfeb garins: pressing process was operated in strong magnetic environment.
2.Sintering of ndfeb blocks: sintering was processed in a vacuum furnace.
3.Wire cutting: ndfeb magnets are fragile materials operated in wire cut machines for the
tailored irregular shapes.
4.Grinding process: Grinding process: To reach the tolerance of magnets.
5.Plating: Neodymium magnets had been treated with different platings to prevent rust.
The popular platings for neodymium magnets are epoxy, nickel, NICUNI ,zinc and even
silver plating and gold plating.
6.Magnetization: the procedure are processed with magnetization machine with magnetic
feild ranged from 2~100 koe.
