, Sintered NdFeB Sintered NdFeB) - after airflow grinding powder Sintered NdFeB permanent magnets of smelting, the coercive force value is very high, and has extremely high magnetic energy, the maximum magnetic energy product (BHmax) above Ferrite (Ferrite) more than 10 times.Its mechanical properties are also very good, can cut different shape and drilling.High-performance products of the highest working temperature can reach 200 degrees Celsius.Because of its material content is easy to cause the corrosion, so according to different requirements must be carried out on the surface of different layer with polish processing.(such as nickel galvanized zinc, nickel, environmental protection, environmental protection, environmental protection, such as nickel, copper and nickel, nickel and copper nickel).Very hard and brittle, with high magnetic, high cost/performance ratio, the work is not suitable for high temperature (> 200 ℃).
