· JVASP-114703· ScAgIr

ScAgIr is a ternary intermetallic compound combining scandium, silver, and iridium. This is an experimental research material rather than an established commercial alloy, belonging to the family of high-performance intermetallics being investigated for extreme-environment applications. The compound's notable characteristics—including its density and elastic properties—position it as a candidate for specialized aerospace, catalytic, or high-temperature structural applications where conventional superalloys or precious-metal composites reach their limits, though industrial adoption remains limited pending further development and cost analysis.
