· CaAl4

CaAl4 is an intermetallic compound in the calcium-aluminum system, representing a phase that forms under specific compositional and thermal conditions. This material belongs to the broader class of lightweight intermetallics and is primarily of research and development interest rather than a mature commercial product. Its potential lies in lightweight structural applications where the low density combined with intermetallic strengthening could offer advantages, though practical use remains limited due to challenges common to brittle intermetallic phases such as limited room-temperature ductility and processing difficulty.
