· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
