NdFeB magnet is mainly made of Neodymium Iron and Boron,with excellent magnetic property abundant raw material and reasonable prices,NdFeB Magnet can be used as an ideal magnet in mini-motor Permanent magnetic resonance sound device magnetic suspension system,magnetic transmission machine and iatrical apparatus and etc.For NdFeB,its surface is usually treatd with some special methods.The surface treatment method include Zine Nickel Tin Silver Gold plating Phosphor and Spray Epoxy Resin etc.

Wide Applications
With its excellent magnetic property, abundant raw material and reasonable prices, rare-earth permanent magnet can be used as an ideal magnet in mini-motor, permanent-magnet instrument,electronic industry, auto industry, petro-chemical industry,nuclear magnetic resonance,sound device, magnetic suspension system, magnetic transmission machine and magnetotherapy apparatus etc.

NdFeB magnets Chemical composition:
Chemical analysis for sintering NdFeB magnets material based on intermetallic compounds RE2Fe14B,main composition is NdFeB magnet is (RE), (Fe) (B),thereinto thulium (Nd), in order to obtain different performance can instead by thulium of (Dy),(Pr) etc. also other metal can instead Fe,for example (Co), (Al) etc., smaller content of boron, but it affect tetragonal crystal intermetallics, making the intermetallics with high magnetization,uniaxial anisotropy and curie temperature.
NdFeB magnets Making process:
NdFeB magnet use Powder Metallurgy Process, proportion of material such as: neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, iron, and boron etc., through Mid-frequency Induction Furnace smelting to alloy steel ingot, then broken into power of 3~5um,and forming mold in magnetic field, the green bodies sintering dense and tempering in Vacuum Sintering Furnace, that can earn magnetic properties of blank of permanent magnet. After grinding, drilling, cutting and other processing, last via surface finish, it is good NdFeB magnet.
