· Al4 Au8

Al₄Au₈ is an intermetallic compound in the aluminum-gold system, representing a specific stoichiometric phase that forms at elevated temperatures or through controlled synthesis. This material belongs to the family of precious-metal-reinforced aluminum alloys, which are primarily of research and specialized industrial interest rather than mainstream engineering use. Al₄Au₈ and related Al-Au phases are investigated for potential applications in electronics, thermal management, and high-temperature coatings, though adoption remains limited due to cost and the availability of more established alternatives; the material is notable in materials science for understanding phase behavior in binary noble-metal systems and exploring novel strengthening mechanisms at the nanoscale.

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.
