· AlCu8Ni

AlCu8Ni is a precipitation-hardening aluminum-copper-nickel alloy belonging to the 2xxx series family, designed to achieve high strength through heat treatment while maintaining reasonable ductility. This alloy is used primarily in aerospace and defense applications requiring strong, lightweight structural components that can withstand moderate service temperatures, competing with other age-hardenable aluminum alloys where copper content provides strength but requires careful processing to avoid sensitization. The nickel addition enhances creep resistance and thermal stability, making it suitable for elevated-temperature service where conventional 2024 or 2014 aluminum alloys would be insufficient.

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.
