Cobalt osmium (CoOs) is a metallic intermetallic compound combining cobalt and osmium, belonging to the family of refractory metal alloys. This material is primarily of research and experimental interest rather than established production use; it combines the hardness and corrosion resistance of osmium with cobalt's ductility and magnetic properties, making it a candidate for high-performance applications requiring extreme durability and chemical inertness. Industrial adoption remains limited due to cost, difficulty in processing, and the availability of more mature alternatives, but the material family shows potential in aerospace, catalysis, and wear-resistant coating applications where conventional materials fall short.

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.
