Cadmium – Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a “sacrificial coating,” corroding before the substrate material.¬†Cadmium plating is widely used in some applications in the marine, automotive,¬†aerospace, military, and aviation fields.

Cadmium plating (or “cad plating”) offers a long list of technical advantages such as excellent corrosion resistance even at relatively low thickness and in salt atmospheres, softness and malleability, freedom from sticky and/or bulky corrosion products, galvanic compatibility with aluminum, freedom from stick-slip thus allowing reliable torqueing of plated threads, can be dyed to many colors and clear, has good lubricity and solder ability, and works well either as a final finish or as a paint base.
