· JVASP-74481· BeCuP

BeCuP is a beryllium-copper-based alloy that combines the lightweight and stiffness characteristics of beryllium with copper's electrical and thermal conductivity and workability. This material is primarily used in precision applications where a combination of high strength, dimensional stability, and electrical properties is required, making it particularly valuable in aerospace, defense, and electronics sectors where traditional copper alloys or aluminum alternatives cannot meet simultaneous mechanical and conductive demands.

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.
