SmCo4Cu
metal· JVASP-106745· SmCo4Cu
SmCo4Cu is a samarium-cobalt-based intermetallic compound belonging to the rare-earth permanent magnet family, with copper as a minor alloying addition. This material is primarily developed for high-temperature magnetic applications where conventional rare-earth magnets lose performance, offering enhanced thermal stability and corrosion resistance compared to standard SmCo5 compositions. Its use is concentrated in aerospace, defense, and industrial motor applications requiring magnets that maintain strength at elevated temperatures and in harsh chemical environments.

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.
