· JVASP-67056· BeCuSb

BeCuSb is a beryllium-copper-antimony ternary alloy that combines the high strength and thermal conductivity of beryllium-copper with antimony addition, likely for enhanced wear resistance or damping characteristics. This material belongs to the beryllium-copper family, a class of precipitation-hardenable alloys valued in precision applications requiring both electrical conductivity and mechanical strength. The specific BeCuSb composition is relatively niche and may be encountered in specialized aerospace, electrical contacts, or bearing applications where antimony's hardening or self-lubricating properties address particular design constraints.

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.
