Fastener Plating Information | CDE Fasteners, Inc.

Cadmium & Wax. Cadium plating results in a smoother surface and greater resistance to white oxidation spots than zinc plating. However, cadmium is a much more toxic metal than zinc, which makes the plating process more difficult and costly. The standard most commercial platers use when applying cadmium is a minimum thickness of .0002 inches.

Cadmium Plating: What Is It and What Are Its Benefits?

The Benefits of Cadmium Plating. Cadmium Plating offers various technical benefits that include low levels of galvanic corrosion when in contact with aluminum. It also provides corrosion resistance in aquatic environments. Cadmium plates surfaces are also resistant to mold and bacteria growth. It is pliant and can be soldered almost as well as tin.

Cadmium Plating for Aerospace and Defense

Cadmium plating, also known as "cad plating," is an electroplating process that creates a sacial coating. The plating will corrode before the underlying substrate of steel, copper, iron, brass, or aluminum. Cad plating is widely used for plating in aerospace and defense applications that require additional corrosion resistance.

Surface finishing treatments

Zinc Plating Steel fasteners can be electro-plated with zinc for better corrosion resistance and usually to a thickness of 200 – 300 micro inches (.0002" - .0003"). Fasteners that have been zinc plated have a shiny silver finish. It is a sacial finish that by forming a "galvanic cell" corrodes before the underlying steel.
