AlCl2

AlCl₂ is an aluminium chloride compound that exists primarily as a research material rather than a conventional engineering alloy. This compound belongs to the aluminium halide family and is of interest in materials chemistry, particularly for studies involving lightweight metal systems and chloride-based ceramic or composite matrices. While not widely deployed in standard structural applications, AlCl₂ and related aluminium chlorides appear in specialized contexts such as chemical synthesis, catalysis research, and experimental composite development where aluminium's low density combined with halide chemistry offers theoretical advantages.
