· JVASP-126883· CrAu3

CrAu3 is an intermetallic compound composed of chromium and gold in a 1:3 atomic ratio, belonging to the gold-based intermetallic family. This material is primarily of research and specialized industrial interest rather than commodity use, valued for applications requiring the corrosion resistance of gold combined with chromium's hardening effects. CrAu3 finds application in high-reliability electronics, decorative coatings, and wear-resistant contact materials where gold's nobility and chromium's strength offer advantages over pure gold or conventional alternatives.

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.
