Sintered SmCo Magnet

SmCo magnet is sintered by Sm, Coblt and other rare earth mental material. It's has strong magnetism and higher temperature resistence, which made it a famouse and reliable material for motors, sensors, pumps, and spare parts for aerospace machinery. Besides, it has higher corrosion resistance, so generally no need for coating. But it's very brittle and easy to get scratch and crack.
