· Ta2MoOs

Ta2MoOs is a refractory metal intermetallic compound combining tantalum, molybdenum, and osmium—three elements prized for extreme-temperature stability and corrosion resistance. This is a research-phase material studied primarily in the refractory metals community for ultra-high-temperature structural applications where conventional superalloys begin to fail; it represents the experimental frontier of multi-principal-element refractory systems seeking to improve fracture toughness and creep resistance compared to monolithic refractory metals or traditional Mo–Os binaries.

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.
