· JVASP-71122· BeCuBi

BeCuBi is a ternary copper-beryllium-bismuth alloy that combines the high strength and thermal conductivity of beryllium-copper with bismuth additions, likely for improved machinability or specific property tuning. This material family is primarily encountered in specialized industrial applications where the enhanced workability of bismuth-modified copper-beryllium alloys offers manufacturing or performance advantages over conventional binary Be-Cu systems, though such compositions are relatively niche and may be application-specific or research-oriented.

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.
