Ndfeb products outside the three layers of nickel plating surface is copper and nickel, ndfeb magnet why three layers of plating?
Ndfeb magnets in the process of production have always been such processing way?
Ndfeb manufacturers understand the RuTie after the development of boron products from 2000 to use three outer layer of the processing method.
Three plating layer is, first and foremost, anti-corrosion ability enough, so can't 2 layer or direct copper plating nickel plating because at that time the ndfeb direct copper plating is still a big problem, it is difficult to guarantee the binding force, because ndfeb magnet substrate can replacement of copper in the copper plating solution, the adhesion strength of the copper plating layer there is not enough, and after the nickel plating ndfeb binding force is good, the adhesion strength of the nickel plated copper plating again also need not worry, so still need a layer of nickel plating to ensure ndfeb substrate binding force, are the benefits of copper plating coating defects, less effect on magnetic shielding, all good plating, low marginal effect, plating to the shape change little.
Simple understanding of ndfeb magnet after processing way, I believe you more trust to our product performance ndfeb magnet, used in a variety of electronics, electrical appliances industry, can be in so much our frontal RuTie boron application industry still worry about sales?
On an essay: introduction to ndfeb strong magnet in the future development trend of the next article: why do you say the electromagnet manufacturer in the industry leading.
