· AlAu4

AlAu4 is an intermetallic compound in the aluminum-gold binary system, characterized by a high density and specific crystal structure that emerges from the stoichiometric combination of aluminum and gold. This material is primarily of scientific and specialized industrial interest rather than high-volume production, appearing in research contexts focused on phase diagrams, alloy development, and advanced materials with unique elastic properties. Engineers would consider AlAu4 in niche applications requiring the specific combination of aluminum and gold characteristics—such as specialized coatings, wear-resistant surfaces, or electronics/photonics applications—though its cost and relative scarcity limit adoption compared to conventional aluminum alloys.

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.
