· ZrOs

ZrOs is a zirconium-osmium intermetallic or composite material combining a refractory transition metal (zirconium) with osmium, a dense precious metal from the platinum group. This material family is primarily of research interest, developed to explore high-temperature strength, corrosion resistance, and wear performance in extreme environments where conventional alloys fall short. Industrial applications remain limited, but the material shows potential in aerospace heat shields, high-temperature structural components, and wear-resistant coatings where the density and refractory properties of both constituents can be leveraged.

Regulatory Screening

Environmental

Export Control

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.
