Zinc Electroplating Plants

Product Details:

• Excellent corrosion resistance, generally 5X better than pure zinc.
• Neutral salt spray results consistently achieve 250 hours to white, ...
• Excellent corrosion resistance at high temperatures.
• Highest abrasion resistance of all zinc alloys.
• Coverage for deep recesses.
• Effective replacement for Cadmium Plating.
• Hardness, heat resistance and high-alloy benefits

  Zinc-nickel has a Vickers hardness of 400 to 500 HV — zinc-only deposits only have a hardness of around 100 HV. Because handling and assembly can be a destructive process for softer coatings like zinc and zinc flake, zinc-nickel’s combination of hardness and overall corrosion protection make the alloy deposit ideal for fasteners or components that require further handling or assembly.

  Another excellent benefit of the zinc-nickel alloy deposit is its overall resistance to heat. Many industry specs require baking, and the zinc-nickel deposit can withstand baking temperatures in excess of 200°C for four hours while still achieving 800 hours of neutral salt spray protection to first red rust. Zinc-nickel is commonly used on stampings and fasteners for barrel applications, and heavily used on brake component castings in rack applications.

  Most available zinc-nickel systems produce a similar alloy deposit, with an average alloy range of 12-to-15% nickel content. Early systems included a lower alloy of 5-to-7%, but those systems are obsolete. The chemical technology available in today’s higher-alloy systems produces a bright and ductile deposit with an even thickness and alloyed distribution over a wide current density range. Zinc-nickel is also the best coating choice when a black appearance is needed in the finished part, as the nickel in the alloy suits blackening.
