How to Control the Product Quality of NdFeB Permanent Magnet

NdFeB permanent magnets are also called modern industrial monosodium glutamate. As a high-performance magnetic material of modern industry, it promotes the progress of contemporary technology and society. It is widely used in various fields. How to judge the advantages of permanent magnet products: 1. magnetic properties; 2. The size of the magnet; 3. surface coating.

What are the sintering methods of sintered NdFeB?

The sintering of sintered NdFeB refers to a process in which the green body is heated to a temperature below the melting point of the powder matrix phase and held for a period of time in order to further improve the performance and usability of the magnet, improve the contact properties between the powders, improve the strength, and make the magnet have high-performance microstructure characteristics.

Mainly affect the NdFeB strong magnetic magnet demagnetization (degaussing) of the four factors introduced

Magnets generally refer to NdFeB magnets, which are mainly composed of rare earth praseodymium neodymium and common element iron alloy. At present, this material is widely used in the market, but magnets often encounter magnetic weakening or disappearance in the process of use. It often happens that we summarize the reasons for magnet demagnetization:
