· JVASP-19930· ZnCu

ZnCu is a zinc-copper binary alloy that combines the corrosion resistance of zinc with copper's conductivity and strength, typically used in applications requiring moderate mechanical performance and environmental durability. Common industrial applications include brass components, electrical connectors, decorative hardware, and corrosion-resistant coatings, where the alloy balances cost-effectiveness with reliable performance in mildly corrosive environments. Engineers select ZnCu alloys over pure metals when a combination of workability, electrical properties, and oxidation resistance is needed without the expense of nickel-based or stainless alternatives.

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.
