· AlCrCo2

AlCrCo2 is an intermetallic compound combining aluminum, chromium, and cobalt, representing a high-entropy or multi-principal-element alloy system. This material is primarily of research interest for high-temperature structural applications, where its combination of relatively low density with stiff elastic behavior offers potential advantages over conventional superalloys. While not yet widely deployed in production engineering, AlCrCo2 exemplifies the emerging class of complex metallic alloys being investigated for aerospace turbines, heat-resistant coatings, and extreme-environment components where weight savings and thermal stability are critical.
