· JVASP-80424· Ta2CuOs

Ta2CuOs is an experimental intermetallic compound combining tantalum, copper, and osmium—a complex metallic phase that represents research into high-entropy or multi-principal-element alloys. This material family is investigated for potential applications requiring extreme hardness, thermal stability, or specialized electronic properties, though it remains primarily in the research phase and is not established in high-volume industrial production.
