Strong magnetism, as the name implies, is strong magnetism. NdFeB is divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB has magnetism and corrosion resistance in all directions. However, sintered NdFeB is easy to corrode and needs to be coated on its surface. Generally, there are zinc plating, nickel plating, zinc ring environmental protection nickel, nickel copper nickel, environmental protection nickel copper nickel and so on.
Sintered NdFeB generally has axial and radial magnetization, depending on the required working face.
Today, NdFeB is the strongest magnet among all magnets. According to the proportion of each component in the formula, the magnetic force can be increased or decreased, and the performance indexes are N30-N52, N30M-N50M, N30h-N48h, N30SHN45SHN28UH-N35UH, N28EH-N35EH.
The conventional strong magnetic force is N35 performance in N35-N52 brand (high temperature resistance of 80 degrees), and other high-performance NdFeB strong magnetic forces can be customized according to needs.
