ScAl
metal· ScAl
ScAl is an intermetallic compound combining scandium and aluminum, representing a lightweight metallic system with potential for advanced structural applications. This material belongs to the rare-earth aluminum intermetallic family and remains largely in the research and development phase rather than established high-volume production. ScAl is of particular interest to engineers exploring next-generation alloys where low density combined with elevated stiffness could enable weight-critical aerospace and defense systems, though practical deployment is limited by manufacturing complexity, cost, and limited commercial availability compared to conventional aluminum alloys.

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.
