Strong Permanent Magnet with Rare Earth for Medical Area , MRI/NMR Electric component magnet
 
Product Description & Specification:
 
Applied in the MRI of sintered ndfeb magnet, It needs the high remanence ( Br)  and max. energy product (BH) Max  performance , in order to ensure the high definition and high resolution. Each MRI is used high performance sintered ndfeb magnet up to  5 to 6 tons.
NdFeb magnets are known for their high temperature resistance, making them durable and functional in 
temperatures exceeding 200°C. This quality makes them ideal for heavy industry applications. Sintered 
Neodymium, however, is sensitive to oxidization and easily can be corroded, so magnets usually need surface treatment .
 
1. Grades
 
Range: N35-N52; N35M-N50M;
       N35H-N48H, N35SH-N45SH;
