· JVASP-22285· SmAl8Cu4

SmAl8Cu4 is an intermetallic compound combining samarium, aluminum, and copper—a rare-earth aluminum-copper phase that belongs to the family of ternary metallic systems. This material is primarily of research and development interest rather than established production use, investigated for its potential in high-temperature applications and electronic device components where rare-earth strengthening and thermal stability are valued. Engineers would consider this compound in advanced aerospace, electronics, or materials research contexts where novel intermetallic properties offer advantages over conventional aluminum alloys, though availability, processing complexity, and cost typically limit adoption to specialized applications.

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.
