ErCo5
metal· JVASP-15038· ErCo5
ErCo5 is an intermetallic compound composed of erbium and cobalt, belonging to the rare-earth transition-metal family of materials. It is primarily studied and used in permanent magnet applications, particularly in high-temperature and high-strength magnetic systems where rare-earth elements provide exceptional magnetic performance. The material is notable for its use in specialized aerospace, automotive, and industrial motor applications where thermal stability and magnetic strength are critical design drivers.
