Extremely corrosion resistant

Zinc-Nickel Drum

Zinc-Nickel Drum: Procedure and Advantages

The electro plated zinc-nickel alloy (12 to 15% nickel) is particularly successful in areas with the requirement of extremely high corrosion protection under high temperature loads.

Classic applications of parts with zinc-nickel-coatings are the engine compartment, chassis and the underbody area in automotive as well as offshore applications.

Parts subject to high temperature loads resist against starting base material corrosion in the salt spray test according to DIN EN ISO 9227 for more than 1000 hours.

The post treatment with selected topcoats enables to substantially increase the corrosion resistance and the resistance against chemical substances.

The zinc-nickel coating in the drum is suitable for components with an individual weight of up to approx. 100g-120g. This is a particularly cost-effective process for components which are not directly visible. We offer both transparent and black passivations.
