About the Process

Del's Plating Works offers zinc cobalt plating which provides enhanced corrosion resistance and a bright luster to metal parts. This plating process involves electroplating a zinc and cobalt alloy to the base metal, creating a uniform coating that is ductile and able to withstand greater corrosion resistance than traditional zinc plating.

Zinc cobalt plating is available in four types: Type A (Colorless), Type B (Yellow), Type C (Bronze), and Type D (Black). These types offer different color options for your metal parts.

Our industry-standard ASTM B840 zinc cobalt plating services ensure the highest quality and durability of the finished product. Our facility is equipped to handle high-volume production runs, and we offer fast turnaround times to meet your production deadlines.
