Zinc-Nickel Plating Specification Highlight: FORD – WSS-M1P87

At DeKalb Metal Finishing, we care about closely following and meeting the specifications set forth by the automotive industry. This is a primary reason why we have become specialists in understanding the OEM specifications created for plating automotive parts. The most common questions we get as zinc nickel electroplating experts are regarding Zinc-Nickel (Zn-Ni) plating specifications.

Zinc-nickel plating is a type of electroplating process that involves coating a substrate with a layer of zinc-nickel alloy. This process is commonly used in the automotive industry, as it provides excellent corrosion resistance and wear resistance. There are many specifications that are referenced for zinc-nickel plating, but Ford parts are often plated to the WSS-M1P87 specification from Ford Motor Company:

Ford Motor Company Specification:  FORD – WSS-M1P87

The FORD – WSS-M1P87 specification, also known as the Ford Material Specification for Electroplated Zinc-Nickel Alloy Coatings, is important for plating automotive parts for several reasons:

Corrosion Resistance: Automotive parts are constantly exposed to harsh environmental conditions, including moisture, salt, and various chemicals. The WSS-M1P87 specification ensures that the electroplated zinc-nickel alloy coating provides excellent corrosion resistance, protecting the parts from rust and other forms of corrosion. This is especially crucial for components exposed to road salt, such as underbody parts and fasteners.

Durability: Automotive parts need to withstand rigorous usage and endure mechanical stresses. The zinc-nickel alloy coating specified by WSS-M1P87 offers enhanced durability, with improved wear resistance and the ability to withstand abrasion and impacts. This ensures that the plated parts maintain their integrity and functionality over an extended period.

Compatibility with Subsequent Processes: Plated automotive parts often undergo additional processes such as painting, adhesion, or welding. The WSS-M1P87 specification ensures that the zinc-nickel alloy treatment has good adhesion properties and is compatible with these subsequent processes, allowing for seamless integration and optimal performance of the plated parts within the larger automotive assembly.

Uniformity and Aesthetics: Automotive manufacturers also consider the visual appearance of plated parts. The WSS-M1P87 specification defines parameters for the thickness and uniformity of the zinc-nickel alloy coating, ensuring consistent coverage and a visually appealing finish. This is particularly important for visible components, such as exterior trim or decorative elements.

Compliance and Quality Assurance: Automotive manufacturers often have specific standards and requirements for their suppliers. By adhering to the FORD – WSS-M1P87 specification, plating companies can demonstrate compliance with Ford’s quality standards. This specification provides a clear guideline for both the plating companies and the automotive manufacturers, facilitating quality assurance and consistency in the production of plated automotive parts.

Overall, the FORD – WSS-M1P87 specification plays a vital role in ensuring that plated automotive parts meet the demanding requirements of corrosion resistance, durability, compatibility, aesthetics, and quality set forth by Ford, an American multinational automobile manufacturer.
