metal

· JVASP-18173· UNi4Sn

UNi₄Sn is an intermetallic compound in the uranium-nickel-tin system, representing a specialized research alloy rather than a commercial engineering material. This compound belongs to the family of uranium intermetallics, which have been investigated for nuclear fuel applications and high-temperature structural uses due to uranium's unique nuclear and thermal properties. The material is of primary interest to nuclear engineering and materials research communities rather than conventional industrial applications, with potential relevance in advanced reactor designs or specialized defense/aerospace contexts where uranium-based alloys are permissible.
