Characteristics
NdFeB permanent magnet is based on IMC (intermetallic compound) RE2FE14B. The application of NdFEB makes the instrumentation, electro-acoustic, electric motor; magnetic separation and other magnetization equipment have the much higher performance, smaller size, lighter weight.Westmag Technology Co., Ltd makes the NdFeB magnet by mass production since 1984. The NdFeB made by Westmag has the strengths such as the high-energy, high consistency, low weight loss, good corrosion resistance, and so on. The main surface treatments are zinc, nickel, silver, golden, phosphating or electrophoresis (epoxy).
Applications
NdFeB magnet is widely applied in modern industry and electronic technology because of its high energy force, high coercive force and the high energy density.
