metal· JVASP-100844· Co3ReB4
Co₃ReB₄ is a cobalt-rhenium boride intermetallic compound belonging to the refractory metal boride family. This is a research-phase material studied for its potential combination of hardness, high-temperature strength, and wear resistance, with composition targeting advanced applications where conventional superalloys reach their limits. Industrial adoption remains limited, but the material family shows promise in aerospace and tooling sectors where extreme performance at elevated temperatures or under severe mechanical stress justifies the cost and processing complexity of rhenium-containing 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.
