Applications in electroplating

Nickel compounds from K&E are essential components for numerous coating processes, enabling decorative, functional, and high-precision technical surfaces.

Electrolytic Nickel Plating:

• Nickel sulfate – main nickel source in electrolytes
• Nickel chloride – improves conductivity and anode dissolution
• Nickel sulfamate – enables ductile, low-stress coatings

Electroless Nickel Plating (ENP):

• Nickel sulfate or nickel nitrate – nickel source in ENP baths
• Nickel hydroxide carbonate – used as replenisher to maintain bath nickel content

Anodizing (Aluminum):

• Nickel acetate – sealing agent for anodized aluminum, improving corrosion resistance and appearance

Electroless/chemical nickel plating

(ENP – Electroless Nickel Plating)

Nickel sulfate or nickel nitrate: Serve as a source of nickel in the bath.

Nickel hydroxide carbonate: Used as a replenisher to keep the nickel content in the bath stable.

In combination with hypophosphite, nickel-phosphorus layers are formed that impress with their high hardness, wear resistance, and corrosion resistance.

Typical applications: Mechanical and plant engineering, automotive parts, wear protection, precision components.

Anodizing process (aluminum anodization)

Nickel acetate: Serves as a sealing agent for anodized aluminum surfaces. It closes the pores of the oxide layer, thereby increasing corrosion resistance and decorative effect.

Typical applications: Aluminum components in architecture, automotive, electronics, and consumer goods.
