· JVASP-74449· BeCu4Tc

BeCu4Tc is a beryllium-copper alloy containing tungsten (W) or another refractory element, belonging to the family of high-strength beryllium-copper precipitation-hardened alloys used where extreme strength, thermal conductivity, and electrical conductivity must be combined. This material is employed in aerospace, defense, and precision electronics applications where components must withstand demanding thermal and mechanical conditions while maintaining excellent electrical or thermal properties—such as in missile guidance systems, high-reliability electrical contacts, and advanced heat sinks. The beryllium-copper matrix offers superior fatigue resistance and dimensional stability compared to conventional copper alloys or aluminum bronzes, making it the preferred choice when weight savings and thermal management are equally critical.

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.
