METAL PLATING
ZINC-NICKEL PLATING SERVICES
ZINC-NICKEL
Our zinc nickel plating service provides a coating that offers greater corrosion protection, more wear resistance and limits the thermal stress to parts subjected to higher operating temperatures than zinc electroplated coatings alone.
Electroplated Zn-Ni coatings also have good throwing power to better coat blind holes and recesses. Zn-Ni alloy coatings are usually composed of approximately 85% zinc and 15% nickel and quite often are used as a base layer under trivalent chromium. zinc nickel plating typically has a dull gray finish in its alloy form but can be chromated to a black zinc finish.

Finish and Processing Options
Barrel Electroplated Zinc Nickel Coatings
Zinc nickel electroplating is typically deposited on iron and steels. Northeast Metal Works offers the advantage of high volume processing on our barrel zinc nickel plating line.
Corrosion Resistance
Northeast Metals Works zinc nickel plating service has the capability to perform salt spray corrosion resistance testing according to ASTM B117 on our finished parts. Electroplated zinc nickel coated carbon steel parts with a trivalent chromium conversion coating typically achieve up to 1000 hours of protection against attack on the substrate in the salt spray test.
