UAlNi

UAlNi is an intermetallic compound combining uranium, aluminum, and nickel, belonging to the family of uranium-based metallic materials. This is primarily a research and specialized material rather than a commodity alloy, investigated for applications requiring the unique properties that uranium intermetallics can provide—particularly high density and specific stiffness characteristics. The material's engineering interest lies in niche defense, nuclear, and aerospace contexts where uranium's nuclear or density properties are leveraged, though its use is heavily restricted by regulatory and proliferation concerns.
