Postato il 06/14/2022 : 16:17:46 Samarium cobalt magnet (SmCo) is one of the rare earth permanent magnets, mainly composed of SmCo5 and Sm2Co17. The anti-corrosion, rust-proof and high-temperature resistance is stronger than that of NdFeB magnets. Samarium Cobalt magnets are modified by alloying, which will completely change the world's rail transit mode.https://www.chinamagnetssupplier.com/smco-magnet/
