· JVASP-129455· CrCu

CrCu is a chromium-copper alloy that combines the corrosion resistance of chromium with copper's thermal and electrical conductivity. This material is employed in applications requiring both wear resistance and thermal performance, particularly in electrical contacts, switch components, and wear-resistant overlays where traditional copper alloys alone would be insufficient. The chromium addition enhances hardness and corrosion resistance compared to pure copper, making it a pragmatic choice for environments with moderate mechanical and chemical 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.
