· JVASP-153137· Be12Co

Be12Co is an intermetallic compound in the beryllium-cobalt system, representing a hard, brittle phase that forms at specific compositional ratios. This material is primarily of research and specialized industrial interest rather than a commodity alloy, valued for applications requiring exceptional hardness and thermal stability combined with beryllium's low density. Be12Co appears in aerospace and high-performance tooling applications where wear resistance and lightweight design are critical, though its brittleness, toxicity concerns during processing, and manufacturing complexity limit broader adoption compared to conventional tool steels or tungsten carbides.

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.
