· JVASP-110261· CoIr

CoIr is a cobalt-iridium binary alloy combining two refractory transition metals with high density and stiffness. It is employed primarily in high-temperature and corrosion-resistant applications where extreme durability and stability are critical, particularly in aerospace, chemical processing, and precision instrumentation where conventional alloys would degrade. The addition of iridium to cobalt enhances oxidation resistance and wear performance at elevated temperatures, making it valuable for applications requiring both mechanical integrity and environmental resistance, though its high cost and density limit use to specialized engineering scenarios.

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.
