Product Description
SmCo Rare Earth Magnets Overview

Two common compositions of SmCo magnets are Sm1Co5 and Sm2Co17. Generally, the cost of SmCo magnets is higher than NdFeB magnets. As a big advantage, SmCo magnets can operate at higher temperatures up to 300 degrees Centigrade. SmCo magnets are widely used in applications in which higher operating temperature and higher corrosion and oxidation resistance are crucial. The main ingredient of SmCo permanent magnet is metal cobalt(CoY99.95%). So its price is high!
