摘要: Rare earth (RE) magnets have become virtually indispensible in a wide variety of industries such as aerospace, automotive, electronics, medical, and military. RE elements are essential ingredients these high performance based on intermetallic compounds RECo5, RE2TM17 (TM: transition metal), RE2TM14B. known for their superior magnetic properties—high induction, coercive force. These properties arise due to the extremely magnetocrystalline anisotropy made possible by unique 3d-4f interactions between metals rare earths. For more than 40 years, remain number one choice applications that require fields extreme operating conditions—high demagnetization forces temperature. EEC produces specializes RECo5 type sintered magnets. Samarium gadolinium key powder metallurgical magnet production processes which include melting, crushing, jet milling, pressing, sin...
