· JVASP-41835· Sc3Al

Sc3Al is a scandium-aluminum intermetallic compound that combines the lightweight characteristics of aluminum with scandium's strengthening effects, forming an ordered metallic phase. This material is primarily of research and developmental interest for aerospace and high-performance applications where weight reduction and strength are critical; scandium-aluminum systems are being explored as alternatives to conventional aluminum alloys for demanding structural components. The intermetallic nature of Sc3Al offers potential for elevated-temperature stability and strength retention that exceed standard aluminum alloys, though manufacturing and cost considerations have limited widespread industrial adoption compared to more mature alloy systems.

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.
