MoIr
metal· MoIr
MoIr is a refractory metal alloy combining molybdenum and iridium, designed to retain strength and stability at extreme temperatures where conventional superalloys fail. This material is primarily investigated for aerospace and high-temperature industrial applications where both thermal resistance and mechanical integrity under severe conditions are critical; it competes with established refractory alloys and tungsten-based systems by offering a balance of density, stiffness, and oxidation resistance in specialized extreme-environment niches.

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.
