· AlNi2

AlNi2 is an intermetallic compound in the aluminum-nickel system, representing a stoichiometric phase that forms at specific composition ratios. This material is primarily of research and metallurgical interest rather than a widespread commercial alloy, studied for its role in aluminum-nickel phase diagrams and as a strengthening phase in precipitation-hardened aluminum alloys. Its significance lies in understanding intermetallic precipitation behavior and thermal stability in multi-phase aluminum systems rather than as a standalone engineering material.
