· JVASP-37899· Cr3Cu

Cr3Cu is an intermetallic compound combining chromium and copper in a 3:1 ratio, belonging to the family of transition metal intermetallics. While not a mainstream commercial alloy, this material is of interest in research contexts for potential applications requiring the combined corrosion resistance of chromium with copper's thermal and electrical conductivity, though its brittleness and processing challenges limit current industrial adoption compared to more established chromium alloys and copper-based systems.
