Ir3W

Ir3W is an iridium-tungsten intermetallic compound combining two of the densest and highest-melting refractory metals. This material is primarily explored in high-temperature and extreme-environment applications where conventional superalloys reach their limits, particularly in aerospace, nuclear, and specialized industrial heating contexts where exceptional strength retention, oxidation resistance, and dimensional stability at elevated temperatures are critical. Engineers consider Ir3W-class materials when designing components that must survive prolonged exposure to extreme thermal cycling, corrosive atmospheres, or demanding mechanical loads in applications where material cost and density are secondary concerns to performance and reliability.
