· ZnNi

ZnNi is a zinc-nickel alloy coating or composite material that combines the corrosion resistance of zinc with the hardness and wear resistance of nickel. It is widely used in electroplating and surface treatment applications where enhanced durability and protection against corrosion are critical, particularly in automotive, industrial fasteners, and heavy-duty machinery. Engineers specify ZnNi coatings over conventional zinc plating when components must withstand more aggressive environmental conditions or require superior wear resistance while maintaining cost-effectiveness compared to pure nickel or stainless steel alternatives.

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.
