· JVASP-111529· Co2Re5B4

Co₂Re₅B₄ is a cobalt-rhenium boride intermetallic compound that belongs to the family of refractory metal borides. This material is primarily of research and development interest rather than established commercial production, investigated for applications requiring exceptional hardness, thermal stability, and resistance to oxidation at elevated temperatures. The combination of refractory elements (rhenium and boron) suggests potential use in extreme-environment applications, though industrial adoption remains limited compared to more conventional superalloys and ceramic composites.

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.
