metal· JVASP-142757· Co3Re4B4
Co₃Re₄B₄ is a cobalt-rhenium boride intermetallic compound, part of the ternary metal boride family that combines high-melting-point transition metals with boron for enhanced hardness and refractory properties. This is primarily a research-phase material studied for its potential in extreme-temperature and wear-resistant applications; cobalt-rhenium borides are of interest in aerospace and tooling contexts where conventional superalloys reach their thermal or mechanical limits.

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.
