BeCoCu
metal· JVASP-70294· BeCoCu
BeCoCu is a precipitation-hardening copper-based alloy containing beryllium and cobalt, designed to combine high strength with excellent electrical and thermal conductivity. It is primarily used in aerospace, electronics, and defense applications where lightweight, high-strength components with good electrical properties are critical, such as connector contacts, spring contacts, and precision electronic components that require both mechanical performance and electrical reliability. This alloy is notable for achieving strength levels comparable to steel while maintaining copper's superior conductivity, making it valuable where traditional copper alloys cannot meet combined mechanical and electrical demands.

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.
