· Sc9Al16

Sc9Al16 is an intermetallic compound in the scandium-aluminum system, representing a defined stoichiometric phase rather than a conventional alloy. This material is primarily of research and experimental interest, studied for its potential in high-temperature structural applications where scandium's low density and high melting point can be leveraged alongside aluminum's processability. Engineers would consider this phase for applications demanding lightweight performance at elevated temperatures, though development and scale-up remain limited compared to conventional aluminum alloys or titanium-based alternatives.

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.
