· JVASP-74176· BeCuMo

BeCuMo is a quaternary copper-based alloy containing beryllium and molybdenum, designed to combine the electrical and thermal conductivity of copper with enhanced strength and wear resistance from beryllium and molybdenum additions. This material is primarily used in high-performance electrical contacts, connector systems, and precision tooling where superior conductivity must be paired with mechanical durability and resistance to electrical erosion. Engineers select BeCuMo over pure copper or conventional brass when applications demand both reliable current-carrying capacity and extended service life under arcing or sliding-contact conditions, though handling requires compliance with beryllium occupational safety protocols.

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.
