· Sm143Cu857

Sm143Cu857 is a samarium-copper intermetallic compound representing a rare-earth metal system with potential applications in magnetic and electronic materials. This composition falls within the rare-earth metallurgy family and appears to be primarily of research interest rather than an established commercial alloy. Samarium-copper intermetallics are investigated for permanent magnet applications, magnetic refrigeration, and as precursors for advanced functional materials where rare-earth magnetic properties combined with copper's conductivity may offer performance advantages over single-element alternatives.
