Product Description

Product Description
Manufacturing ProcessSintered Nd-Fe-B permanent magnet material is made by powder metallurgy process. The melted alloy is made into powder and pressed into pressed embryo in magnetic field. The pressed embryo is sintered in vacuum to achieve densification. In order to improve the coercivity of magnet, further heat treatment is usually required.GradeEach type of product is divided into several grades according to the maximum magnetic energy product:N35-N52,N35M-N50M,N30H-N48H,N30SH-N45SH,N28UH-N35UH,N28EH-N35EHMain Magnetic PropertiesIncluding remanence (BR), magnetic polarization, coercivity (intrinsic coercivity) (Hcj), magnetic induction, coercivity (HCB), and maximum magnetic energy product ((BH) max) of permanent magnet materials.Application AreaIt is widely used in permanent magnet motor, loudspeaker, magnetic separator, computer disk driver, magnetic resonance imaging equipment, instruments, toys, packaging, hardware machinery, aerospace and other fields.
