· JVASP-68719· BeCuPb2

BeCuPb2 is a ternary copper-beryllium-lead alloy combining the electrical and thermal conductivity of copper with beryllium's strength and stiffness, and lead's machinability and damping properties. This material composition is primarily explored in precision electrical contacts, connector applications, and specialized bearing materials where the combination of conductivity, wear resistance, and ease of machining is valued. The addition of lead improves chip formation and workability compared to standard beryllium-copper alloys, though material selection depends on balancing performance requirements with health and environmental considerations related to beryllium and lead exposure.

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.
