AlCu4
metal· JVASP-141933· AlCu4
AlCu4 is an aluminum-copper binary alloy containing approximately 4% copper by weight, belonging to the 2xxx series aluminum alloy family. This composition delivers improved strength and hardness compared to pure aluminum while maintaining reasonable machinability, making it relevant for structural and wear-resistant applications where moderate strength is required without the complexity of multi-element precipitation-hardened systems.

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.
