TiIr
metal· TiIr
TiIr is an intermetallic compound combining titanium and iridium, belonging to the class of refractory metal intermetallics. This material combines titanium's relatively low density with iridium's exceptional hardness, corrosion resistance, and high-temperature stability, making it of interest for extreme-environment applications where conventional superalloys fall short. TiIr remains primarily in research and development phases rather than widespread commercial production, but represents the potential of transition metal intermetallics to enable next-generation aerospace and chemical processing systems that operate at elevated temperatures with severe corrosive exposure.

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.
