· JVASP-67114· BeCuSn

BeCuSn is a beryllium-copper-tin ternary alloy that combines the high strength and thermal conductivity of beryllium-copper with tin for enhanced workability and corrosion resistance. It is used in precision applications requiring excellent electrical and thermal conductivity paired with moderate strength, particularly in aerospace connectors, springs, and contacts where weight savings and performance reliability are critical.

Export Control

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.
