· JVASP-71465· BeCuSe

BeCuSe is a ternary copper-based alloy containing beryllium and selenium additions, belonging to the family of specialty copper alloys designed for enhanced mechanical and thermal properties. This material is typically employed in electrical contacts, connectors, and precision spring applications where high strength, good electrical conductivity, and wear resistance are required simultaneously. The beryllium addition provides significant strengthening and thermal conductivity improvements over standard copper alloys, while the selenium component influences machinability and microstructural stability, making this alloy a specialized choice for demanding electrical and thermal management applications in aerospace, telecommunications, and high-reliability switching systems.

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.
