Product description: 
The third generation of rare earth permanent magnet NdFeB magnets (NdFeB) magnets are the strongest performance of contemporary permanent magnet, it not only has high remanence, high coercivity, high energy product and high cost performance and other features, and easy processing into a variety of sizes, is now widely used in aerospace, electronics electro-acoustic, instruments, jewelry, leather handbags, packing boxes, toys, medical technology and other required permanent magnetic field means devices, especially for the development of high performance, small size, light a variety of replacement products. 

Surface treatment: 
Sintered NdFeB is a chemical activity of powder metallurgy materials, their characteristics hard and brittle and susceptible to oxidative corrosion. Based on the characteristics of the current taken by the most effective way is surface protective layer. However, the surface of NdFeB sintered magnet in the grinding process due to the presence of degradation generated incomplete layer density resulting pores oxide, and their surface treatment must take the necessary and appropriate pre-treatment plating process, as follows: 
Chamfer → degreasing → pickling → ultrasonic cleaning coating plating → aging → Detection
