Alloy electroplating offers outstanding salt spray protection. At Great Lakes Metal Finishing, Inc we offer both low and high zinc nickel plating. Higher nickel content is ideal for outdoor industries seeking more than 1,000 hours protection to red rust and superior strength. Even our low zinc nickel alloy coating has greater than 700 hours to red rust and still adds a formidable layer of defense.

If you’re unsure of your product’s requirements, referencing the alloy plating specifications will reveal the nickel deposit standards that are right for you.

Typical Nickel Deposit Range for Alloy Electroplating:

Low Zinc Nickel Alloy Coating:
5% – 12% nickel content
High Zinc Nickel Alloy Coating:
10% – 17% nickel content

*High zinc nickel is by far the most sought specification for alloy electroplating.*

Topcoats or Torque and Tension coatings can be applied to both low zinc nickel and high zinc nickel products.
