· JVASP-18039· ScInNi2

ScInNi2 is an intermetallic compound combining scandium, indium, and nickel, belonging to the family of ternary metallic intermetallics. This is a research-phase material with limited commercial production; it is studied primarily for its potential in high-performance structural applications where the combination of relatively low density and significant stiffness could offer weight savings compared to conventional engineering alloys. The material's potential lies in aerospace and automotive sectors where weight reduction and high-temperature stability are critical, though practical applications remain largely experimental pending validation of manufacturability and long-term performance.
