IrRu

IrRu is a ceramic intermetallic compound combining iridium and ruthenium, two refractory noble metals with exceptional hardness and thermal stability. This material is primarily studied for ultra-high-temperature applications and wear-resistant coatings where conventional superalloys fail, particularly in aerospace propulsion systems and extreme industrial environments. Its appeal lies in combining the corrosion resistance and density of noble metals with ceramic-like hardness, making it a candidate for applications demanding both thermal resilience and mechanical performance, though it remains largely in research and specialized industrial use rather than mainstream production.
