· JVASP-67943· BeCrCu2

BeCrCu2 is a copper-based alloy incorporating beryllium and chromium, representing a specialized composition within the beryllium-copper alloy family. This material combines copper's thermal and electrical conductivity with beryllium's strength and stiffness, plus chromium additions for enhanced hardness and corrosion resistance. Industrial applications include precision electrical contacts, high-reliability spring elements, and aerospace fasteners where weight savings, fatigue resistance, and dimensional stability are critical; the beryllium content demands careful handling during manufacturing due to hygiene considerations, making this alloy most suitable for applications where its performance advantages justify the production controls required.

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.
