· JVASP-78842· Cr3Fe

Cr3Fe is an intermetallic compound combining chromium and iron in a 3:1 ratio, belonging to the family of transition metal intermetallics. This material exhibits high stiffness and moderate density, making it relevant for applications requiring rigidity and wear resistance at elevated temperatures. Industrial interest centers on potential use in aerospace components, hard coatings, and wear-resistant structural applications, though Cr3Fe remains primarily in the research and development phase compared to more established ferrous alloys and chromium-iron superalloys.
