· AlSc

AlSc is an aluminum-scandium alloy that combines aluminum's light weight and workability with scandium's grain-refining and precipitation-strengthening properties, resulting in improved strength and thermal stability compared to conventional aluminum alloys. This material finds primary use in aerospace and high-performance applications where weight reduction and elevated-temperature strength are critical, particularly in aircraft fuselage components, rocket structures, and defense systems. AlSc is notably more expensive than conventional Al-Cu or Al-Zn alloys but offers superior creep resistance and fatigue performance, making it the preferred choice when lifecycle cost and structural reliability outweigh material cost considerations.

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.
