· ScNi5

ScNi5 is an intermetallic compound combining scandium and nickel, representing a research-phase metallic material from the rare-earth transition metal family. While not widely commercialized, ScNi5 and related rare-earth nickel intermetallics are investigated for applications requiring high stiffness and specific strength, particularly in aerospace and high-temperature structural contexts where conventional nickel alloys may be insufficient. Engineers would consider this material primarily in advanced research programs or specialized aerospace components where the unusual combination of scandium's low density and nickel's strength offers potential weight savings or enhanced performance over conventional superalloys.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
