· CaAl9Co2

CaAl9Co2 is an intermetallic compound combining calcium, aluminum, and cobalt—a ternary system that falls within the broader class of lightweight metallic intermetallics. This is a research-phase material; it is not yet widely deployed in commercial applications, but compounds in this compositional family are studied for potential use in high-temperature structural applications and advanced alloy development where the combination of light weight and intermetallic strengthening is valued.
