Neodymium(NdFeB) magnets are made from Neodymium, iron, boron(Nd₂Fe₁₄B) and few other rare earth elements under four main production processes-raw material melting/powder making/mould pressing/sintering-to become the semi-finished products that will finally be machined and coated to be the finished parts. The main characteristics: 1)higher remanence(Br); 2)higher Coercivity(Hci) and energy product(BH); 3)lower Curie temperature(Tc). The main Applications: wind generators, DC motors, servo motors, air conditioners, medical equipment, VCM, mobile phones, speakers and magnetic holding and seperation systems etc.
