TiIr3
metal· TiIr3
TiIr3 is an intermetallic compound combining titanium and iridium, belonging to the family of refractory metal intermetallics. This material is primarily of research and developmental interest rather than established in high-volume production, valued for its combination of low density relative to its stiffness and the chemical inertness of iridium, making it a candidate for extreme-environment applications where both weight and thermal/corrosion resistance are critical.

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.
