· Al2 Cu4 Re4

Al₂Cu₄Re₄ is an intermetallic compound combining aluminum, copper, and rhenium in a defined stoichiometric ratio. This is a research-phase material primarily explored for high-temperature structural applications where the rhenium addition provides solid-solution strengthening and oxidation resistance beyond conventional Al-Cu systems. While not yet established in volume production, this material family represents the broader class of aluminum-refractory element intermetallics developed to extend aluminum's utility in aerospace and thermal-management environments where nickel-based superalloys become economically or weight-prohibitively expensive.

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.
