Electroless Nickel Plating

What is Electroless Nickel Plating?

Electroless nickel plating is an auto-catalytic reaction used to deposit a coating of nickel on a substrate. Unlike electrolytic nickel and electroplating, it is not necessary to pass an electrical current through the solution to form a deposit. This plating technique prevents corrosion and wear, and the coating covers even the most complex shapes uniformly. It’s perfect for complex molds, dies, and tooling.

United Surface Finishing offers 3 kinds of electroless nickel plating: high-phosphorous, medium-phosphorous and our proprietary USF-Excel electroless nickel process.

We can plate to the following specifications

MIL-C-26074
AMS-C-26074
AMS 2405
ASTM B733
AMS 2404

Substrates for Electroless Nickel Plating

  • Aluminum, for which we have a dedicated line
  • Steel
  • Stainless Steel
  • Copper
  • Most base metals

Finishes and Options

  • Satin
  • Matte
  • Ground
  • Polished
  • Honed
  • RA (2 and above)

The above finishes are achieved by special pre-plate processes specific to the customer’s request and application.

Performance Porosity Expectation*

USF Excel Neutral Salt Spray per ASTM B117

Process & Base NSS HRS
Medium Phosphorus (7-9% P) 7-12 microns, average base 24-72
>25 microns, average base 48-120
7-12 microns, good base 72-168
High Phosphorus (>10% P) 25-50 microns, average base 240-750
>50 microns, good base to 1,000+

*Note: All operating parameters optimized, all Neutral Salt Spray on properly prepared panels with proper angles in salt spray cabinet. Performance on parts can be variable as significant surfaces change.

Our Production Capabilities

From our state-of-the-art 35,000 square foot facility in Canton, Ohio, we provide plating to customers from across the continental United States. Our production capabilities include:

  • Ni: 3 tons
  • EN Tanks – 42” x 72” x 60” deep (some of the largest in NE Ohio)
  • Ni stripping

From start to finish, we understand that every step of the production process is critical to achieving the standards both we and our customers expect. That is why we can also provide pre- and post-plating services upon request such as abrasive blasting, buffing and polishing, centerless belt-sanding, and stripping. See Extended Services for a complete list.
