The characteristics and manufacturing process of NdFeB Magnets

　　The characteristics of NdFeB Magnets:

　　Neodymium iron boron permanent magnetic material is a permanent magnets' materials, based on the intermetallics Nd2Fe14B.

　　NdFeB Magnets have high energy product and straightening force, at the same time, the advantages of high energy density make the NdFeB Magnets permanent magnetic material in modern industry and electronic technology gained wide application, thus making instruments, electro-acoustic electric, magnetic magnetization equipment miniaturization, lightweight, thin possible.

　　The material characteristics of NdFeB Magnets:

　　NdFeB Magnets have the advantages of high cost performance, with good mechanical properties. Deficiency lies in the low Curie temperature, bad temperature characteristic, and easy to occur powder corrosion, which must adjust its chemical composition and surface treatment method to gain improvement, to achieve practical application requirements.

　　The manufacturing process of NdFeB Magnets:

　　Permanent magnetic material of sintered NdFeB magnets uses powder metallurgy process, the smelted alloy powder is pressed into a pressing pressure embryo in the magnetic field, embryo in an inert gas or Vacuum Sintering reaches densification, in order to improve the coercivity, it usually needs to do aging heat.
