Our Hard Gold Electroplating
Fowler Industrial offers various high-performance electroplated gold options for achieving different degrees of electrical conductivity, finish quality, and corrosion resistance.
24K Gold Plating for Conductivity and Appearance
With our 24K gold plating, we deposit a layer of 99.7% pure gold alloyed with cobalt or nickel. Advantages of this hard gold plate finish include:
- Reflective finish
- Electrical conductivity ideal for contacts, connectors, and other exposed components
- Thin but comprehensive coating that can adhere to surfaces with intricate geometries
Gold Plating Compliant With MIL-G-45204 and ASTM B488 Specifications
Fowler Industrial offers heavy gold electroplating that adheres to MIL-G-45204 and ASTM B488 specifications. These standards outline the required purity, thickness, and hardness of gold coatings in military and engineering applications.
For example, Type I coatings must be 99.7% pure, a purity level that ensures low contact resistance and increased solderability. Type II coatings must be at least 99.0% pure, which makes the plating harder and more resistant to wear. Before either plating process, our team applies a nickel underplate to the workpiece, which prevents diffusion and enhances adhesion. We meet and maintain these thresholds so that each finish provides protection in its intended environment.
Benefits of Hard Gold Plating
Hard gold plating offers several advantages across different industries and applications.
High Electrical Conductivity
Gold is one of the most electrically conductive metals in the world. While copper and silver are slightly more conductive, gold is resistant to oxidation. As a result, gold coatings provide more consistent and reliable electrical conductivity over time, especially in environmental extremes. Manufacturers apply hard gold coatings to contacts and connectors that require long-term, consistent conductivity.
Corrosion and Heat Resistance
Because hard gold alloys are resistant to corrosion, electroplated gold protects underlying metal materials that might otherwise oxidize, corrode, or tarnish. Gold also retains its characteristics at high temperatures and conducts heat well.
Bright Finish With Long-Lasting Durability
Hard gold imparts a bright and reflective finish that’s aesthetically pleasing and sleek, ideal for uncovered or visible parts. The alloying metals in hard gold, such as nickel and cobalt, make the plated layer harder, more wear-resistant, and more resistant to mechanical stress.
All of these characteristics increase the long-term performance of specialty components. The gold layer enhances electrical conductivity, stability under heat, and visual appearance, while the alloying metals improve hardness and durability.
