Tm2CuOs

Tm2CuOs is an intermetallic compound combining thulium (a rare-earth element), copper, and osmium—a dense, hard metallic phase belonging to the family of multi-component refractory metals. This material is primarily of research and academic interest rather than established industrial production; it represents exploratory work in high-entropy or complex intermetallic systems where the combination of rare-earth and transition metals may confer unusual mechanical or functional properties.
