· Re1 Os1 Ru1

Re1Os1Ru1 is an equiatomic ternary alloy combining rhenium, osmium, and ruthenium—all refractory transition metals with extremely high melting points and exceptional hardness. This material exists primarily in research contexts as a candidate high-entropy or multi-principal-element alloy, investigated for extreme-temperature structural applications where conventional superalloys reach their limits. The combination of these three noble refractory metals offers potential for ultra-high-temperature environments, oxidation resistance, and wear resistance, though practical engineering applications remain limited due to density, cost, and processing challenges inherent to the constituent metals.

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.
