BeCuSn2
metal· JVASP-71535· BeCuSn2
BeCuSn2 is a beryllium-copper-tin ternary alloy combining the high strength and thermal conductivity of beryllium-copper with tin additions for enhanced wear resistance and corrosion protection. This specialized alloy is used in precision applications where a combination of high strength, electrical conductivity, and dimensional stability is required, particularly in aerospace fasteners, electrical contacts, and high-reliability connector systems where traditional copper alloys or aluminum alternatives cannot meet simultaneous thermal, mechanical, and electrical demands.

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.
