Generally, SmCo magnetic steel only has sintered magnetic steel. The production process is mainly cutting and grinding. The specification and size can be customized and processed according to the customer's requirements. The characteristics of SmCo are high temperature resistance, not easy to oxidize and corrosion resistance. Therefore, most of the general high-temperature motors and aviation products use SmCo magnets.
At present, the price of rare earth materials and high-performance neodymium iron boron materials in China has risen sharply. The price of some high-temperature products of N35EH and n35uh has been much higher than that of SmCo, which can be perfectly replaced by SmCo products at present. Especially for motor products, SmCo tile has higher temperature resistance than NdFeB magnet, and has the same stability as NdFeB material.
