· JVASP-18687· ZnCu2Ni

ZnCu2Ni is a ternary copper-based alloy incorporating zinc and nickel elements, belonging to the family of copper alloys used for enhanced mechanical and corrosion-resistant properties. This alloy composition is typical of specialized brasses and bronzes engineered for applications requiring a balance of strength, wear resistance, and environmental durability. The material is primarily selected for marine hardware, electrical contacts, and industrial fasteners where corrosion resistance and moderate strength are critical performance requirements.

Export Control

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.
