· Al1 Cu1

Al₁Cu₁ is an intermetallic compound in the aluminum-copper system, characterized by a 1:1 atomic ratio that produces a distinct crystal structure differing from conventional aluminum alloys. This material is primarily of research interest for understanding phase behavior and mechanical properties in the Al-Cu binary system; industrial applications remain limited due to brittleness and processing challenges compared to age-hardened aluminum alloys like 2024 or 7075. Engineers may encounter this compound in academic studies of precipitation hardening mechanisms or as a reference phase when optimizing copper-containing aluminum alloys for structural 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.
