Al2Ni3

Al2Ni3 is an intermetallic compound from the aluminum-nickel system, characterized by a defined stoichiometric composition that creates a rigid crystal structure distinct from solid-solution alloys. This material is primarily of research and specialized industrial interest, appearing in high-temperature applications and composite reinforcement where its thermal stability and hardness can be leveraged, though it remains less common than conventional aluminum or nickel alloys due to brittleness and limited ductility at room temperature. Engineers consider Al2Ni3 for niche applications where intermetallic strengthening or high-temperature performance outweighs the need for conventional workability.
