Which specialties does the Sintered NdFeB magnets have?

　　Sintering neodymium iron boron ( Sintered NdFeB magnets ) -- sintered nd iron boron permanent magnets are produced through the airflow grinding powder, coercive force value is very high, and has a very high magnetic energy, the maximum magnetic energy product ( BHmax ) is higher than the ferrite ( Ferrite ), which is more than 10 times.

　　Sintered NdFeB magnets’ mechanical properties are also quite good, can cut different shape and drilling. High performance products, the highest working temperature can reach 200 degrees celsius. Because its material content is easy to rust, according to the different requirements, we should do different surface coating processing. ( such as zinc, nickel, zinc, nickel, nickel, nickel and copper in environmental protection environmental nickel copper and nickel).

　　Sintered NdFeB magnets are very hard and brittle, high resistance to demagnetization, high cost and performance ratio, does not apply to high operating temperatures (> 200 ° C).
