The Difference Between Bonded Ndfeb And Sintered Ndfeb

1,Bonding Ndfeb

Bonded ndfeb, Nd2Fe14B composition, is a synthetic magnet. Bonded NdFeB magnets are magnets made of a mix of quickly quenched NdFeB magnetic powder and binder through “pressed molding” or “injection molding”.

The size precision of bonding magnet is high, which can be made into magnetic components with relatively complex shape, and it has the characteristics of one-time forming and multi-pole orientation.Bonding ndfeb high mechanical strength, and other supporting components can be formed at a time.

2, Sintering

Sintering, which refers to the conversion of powdery materials into dense bodies, is a traditional process.This process has long been used to produce ceramics, powder metallurgy, refractories, ultra-high temperature materials and so on.

Generally speaking, after the powder is formed, the compact body obtained through sintering is a kind of polycrystalline material, whose microstructure is composed of crystal, vitreous body and stomata.The sintering process directly affects the grain size, pore size, grain boundary shape and distribution in the microstructure, and thus affects the properties of materials.
