China Magnets Source Material Limited is a Chinese supplier of rare earth permanent magnets, including Neodymium magnet and Samarium cobalt. Compared to NdFeB magnets, SmCo magnets offers unique capabilities such as higher energy density at elevated temperatures. Their maximum operating temperature is ≥250 °C, which strongly exceed those of NdFeB permanent magnets. SmCo flux output varies much less with respect to temperature, meaning the device performance can truly be optimized. Another difference with NdFeB magnets is that the supply risk and price instability of SmCo magnets do not depend on the rare-earth element – Sm, but rather on the cobalt in the magnet alloy. Therefore, the price of Samarium Cobalt block material is more stable. As smco5 & sm2co17 magnet manufacturer, we supply Samarium Cobalt for mass production at factory price. But we also custom smco magnets for prototype development and low-volume production.
