· ScNi2

ScNi₂ is an intermetallic compound combining scandium and nickel, belonging to the family of transition metal intermetallics with ordered crystal structures. This material is primarily of research and development interest rather than established in high-volume industrial production, being investigated for applications requiring combinations of light weight and structural rigidity. The Sc-Ni system is studied for potential use in aerospace, automotive, and high-performance applications where reduced density combined with stiffness offers design advantages over conventional alloys.
