Zinc Nickel Plating
If you are interested in getting into Zinc Nickel plating, you must first decide what type: acid or alkaline. Both systems provide over 1000 hours of salt spray, can be plated in both rack and barrel and provide an alloy of 12-15% Nickel.
Acid Zinc Nickel Advantages
- Faster plating rate – up to 30% faster than alkaline systems
- Can be plated on hardened and cast metals
- Lower operating cost
- Uses Zinc and Nickel anodes – no costly mixed metal anodes
- No carbonates to freeze out
- Easier to waste treat – no cyanide generation
Alkaline Zinc Nickel Advantages
- First system developed & most common in the market
- Liquid additives with single rail mixed metal anodes
- Very good alloy uniformity
- Less tendency to burn in high current density
- Good throwing power

NiClipse™ C is an acid zinc/nickel plating process that offers exceptional corrosion resistance, uniform alloy distribution and covering power, especially over cast substrates. NiClipse™ C deposits easily accept clear, yellow or black passivates. NiClipse™ C produces a fully bright deposit for rack or barrel applications.
- 1,000-3,000 hours to red rust in salt spray
- Uniform nickel content between 12–16%
- Produces ductile zinc nickel deposits
- Low temperature application
- Suitable for rack and barrel
- Can be full bright or semi-bright
- Ammonium chloride free
Ziniloy™ 3028 is an alkaline zinc/nickel alloy plating process offering exceptional corrosion resistance. Ziniloy™ 3028 produces bright deposits of a zinc/nickel alloy with excellent distribution and covering power. Ziniloy™ 3028 is suitable for either rack or barrel plating. Ziniloy™ 3028 deposits easily accept clear, yellow or black passivates. Passivated deposits retain excellent corrosion resistance, even after 24 hours of a 250°F (120°C) temper.
- 1,000+ hours to red rust in salt spray
- Nickel alloy between 12-15% across all current density ranges
- Readily accepts passivates and conversion coatings
- Bright zinc nickel deposits
- Suitable for rack and barrel
Pavco ZiNi™ Strip is specifically designed for stripping Zn/Ni alloy plating from steel substrates. ZiNi™ Strip eliminates the nickel smut that remains with typical stripping media. Reduction of the overall concentration of acid makes ZiNi™ Strip an economical method for stripping both alkaline and chloride based zinc/nickel alloys.
- Is used in hydrochloric acid.
- Eliminates all nickel smut.
- Speeds up the stripping process.
- Requires lower acid concentrations.
- Used at room temperature.
- Economical to use.
