· Al8 Cu4 Sm1

Al8Cu4Sm1 is an intermetallic compound combining aluminum, copper, and samarium—a rare-earth addition that modifies phase stability and thermal properties of the Al-Cu base system. This is primarily a research-stage material rather than an established commercial alloy; samarium addition to aluminum-copper systems is studied to refine microstructure, improve creep resistance at elevated temperatures, or enhance specific strength-to-weight ratios for advanced aerospace or automotive applications.

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.
