Sintered NdFeB introduction:
Main performance: including the magnetic remanence of permanent magnetic materials (Br), magnetic polarization coercive force (intrinsic coercivity) of magnetic induction intensity (Hcj) of coercivity (Hcb), maximum energy product ((BH) max)
The magnetic properties of the auxiliary:
Including the relative recoil permeability of permanent magnetic materials (REC), temperature coefficient of remanence (alpha (Br)), magnetic polarization coercive force temperature coefficient (alpha (Hcj)) and Curie temperature (Tc) classification number
The classification of materials: sintered neodymium iron boron permanent magnetic material on the basis of coercivity from low to high were divided into N, M, H, SH, TH, UH, VH, EH, GH, AH.
Manufacturing process: things powder metallurgy process using sintering neodymium iron boron permanent magnetic material, melting alloy powder is pressed into the pressure in the magnetic field in the embryo, embryo compression in densification achieved an inert gas or vacuum sintering, in order to improve the magnet coercive force, often requiring aging heat treatment.
Application: materials of sintered neodymium iron boron permanent magnetic material has outstanding magnetic properties, widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields, there are the more common permanent magnet motor, speaker, magnetic separator, the computer disk drives, magnetic resonance imaging instrument etc..
The magnetic properties of sintered neodymium iron boron:
