Magnetic Powder

NdFeB Powder

At present,the product range of our magnets covers five kinds of magnetic powder and all kind of bonded magnet.They can be used in the automobile industry,office automation,electric toys and magnetic curing products,etc.because they have high quality and high strength and they can be made to complicated shape.

Note: (1) The standard particle size of melt-spun NdFeB permanent magnetic powder:

        > 300 (60 mesh)   < 1%

        > 150 (100 mesh)   20-40%

        > 75 (200 mesh)    50-70%

        > 75 (200 mesh)   < 10%

(2) We can manufacture it according to other sizes and magnetic properties required by clients.
