· JVASP-67844· BeCo4Cu

BeCo4Cu is a beryllium-cobalt-copper ternary alloy combining the lightweight and stiffness benefits of beryllium with the strength and thermal conductivity contributions of cobalt and copper. This material belongs to the family of high-performance beryllium alloys, historically used in demanding aerospace and defense applications where weight reduction and structural rigidity are critical; however, beryllium's toxicity and processing hazards have limited its modern adoption in favor of alternative titanium and aluminum systems in most civil engineering sectors.

Export Control

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.
