Enhanced Protection with Distinctive Identification

Metal Finishing Group provides Cadmium Yellow electroplating services, delivering a robust protective coating distinguished by its vibrant yellow finish. This process involves applying a pure cadmium layer to your components, followed by a yellow dichromate conversion coating. The yellow chromate significantly enhances the cadmium’s already strong corrosion resistance and provides clear visual identification.

Cadmium Yellow is often chosen when components require superior sacrificial protection and the functional benefits of cadmium, coupled with a distinct color for aesthetic coding, assembly identification, or specific application requirements. This finish creates a thin, durable layer that excels in preventing corrosion, particularly in harsh or marine environments, while also serving as a visual indicator.

Our Cadmium Yellow Capabilities: Durability and Visibility

We offer precise Cadmium Yellow electroplating services, ensuring a uniform, high-quality finish for your critical parts.

  • Distinctive Yellow Finish: Provides a bright, easily recognizable yellow appearance for component identification or visual appeal.
  • Superior Corrosion Protection: The yellow dichromate actively boosts the cadmium layer’s ability to protect against rust and environmental degradation, often providing longer salt spray resistance compared to clear chromates.
  • Optimal Adhesion Surface: Maintains the excellent bonding surface properties of cadmium for subsequent adhesives or coatings.
  • Rack and Barrel Plating: We accommodate both rack and barrel plating methods to suit various part sizes and production volumes.
  • Thickness Control: We achieve precise plating thicknesses, ensuring optimal performance without affecting critical dimensions.
  • In-house Quality Verification: We conduct in-house salt spray testing and use X-Ray fluorescent spectrometry for accurate thickness analysis.

Properties of Cadmium Yellow:

Cadmium Yellow combines the well-known benefits of cadmium plating with the specific advantages of a yellow chromate finish:

  • Exceptional Sacrificial Protection: The cadmium corrodes sacrificially, protecting the underlying steel, iron, or copper from rust, with the yellow chromate offering an additional layer of defense.
  • Low Electrical Resistance: Ensures efficient electrical conductivity for various applications.
  • Superior Solderability: Facilitates reliable electrical connections through easy soldering.
  • Favorable Galvanic Compatibility: Integrates well with aluminum, helping prevent galvanic corrosion.
  • Natural Lubricity: Reduces friction and galling, extending the life of moving or mating parts.
  • Mold and Bacteria Resistance: The surface resists the growth of mold or bacteria.
  • Visual Identification: The yellow color serves as a clear indicator for different parts, processes, or specifications.

Applicable Specifications We Adhere To:

Our Cadmium Yellow processes consistently meet or exceed crucial industry standards, ensuring the quality and performance of your components. We regularly process to:

  • QQ-P-416 Type II (Yellow)
  • ASTM B766 Type II
  • SAE AMS 2400 (where applicable for yellow finishes)
  • Many other customer-specific requirements.

Typical Cadmium Yellow Applications:

Cadmium Yellow is vital for numerous applications across demanding industries where both protection and visual coding are required:

  • Aerospace Components: Used for fasteners, brackets, and other parts where corrosion protection is paramount and a colored finish is required for identification.
  • Electronic Assemblies: Provides conductive and protective surfaces with color coding for various electronic components.
  • Fasteners: Offers enhanced corrosion protection and clear identification for nuts, bolts, and washers.
  • Automotive: Applied to various under-the-hood components requiring distinct visual coding.
  • Industrial Machinery: Protects parts in harsh environments requiring corrosion resistance and specific color designation.
  • Marine Applications: Provides robust protection for components exposed to challenging saltwater conditions.
