· JVASP-102735· IrOsRu

IrOsRu is a ternary refractory metal alloy combining iridium, osmium, and ruthenium—three platinum-group metals known for exceptional hardness, corrosion resistance, and thermal stability. This material is primarily encountered in specialized research and high-performance industrial applications where extreme conditions demand materials that maintain strength and chemical inertness at elevated temperatures and in corrosive environments. Its use remains limited to niche sectors due to scarcity, cost, and processing complexity, but it is valued in applications requiring superior oxidation resistance and durability where conventional superalloys or tungsten-based alternatives fall short.

Regulatory Screening

Environmental

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.
