· JVASP-35602· Cr3Co

Cr3Co is an intermetallic compound in the chromium-cobalt system, combining the corrosion resistance of chromium with the strength and high-temperature stability of cobalt. This material family is explored primarily in research contexts for applications demanding exceptional hardness, wear resistance, and thermal stability, though commercial adoption remains limited compared to conventional superalloys and stainless steels.
