Five Key Benefits of Cadmium Plating

Cadmium plating is the process of electro deposition of the metal coating to the surface of the work piece. This very simple yet very effective process has been protecting the metal items ( sun-glo/cadmium-plating ) and other similar materials for over 100 years. It forms a strong and adaptive metal coating on the substrate which protects it from the corrosion.

Cadmium plating is typically used in the aerospace industry and marine industry. However, due to the toxic nature of the metal, this coating is not used in some industries for specific purposes.

Cadmium plating offers a wide range of benefits. Let’s have a look at the five key benefits of cadmium plating.

Excellent Adhesion

Cadmium plating has phenomenal adhesion properties. Cadmium metal coating on any object offers exceptional bonding surface for adhesives. That’s why it is the preferred choice of metal coating for the aerospace industry. It works well as either the final surface or paint base.

Corrosion Resistance

Cadmium plating is well known for its corrosion-resistant capabilities. Even in the harsh climatic conditions, it can withstand easily and protect the substrate from rusting. This metal coating is ideal for salty water environments. That’s why it is favored metal coating for the marine environments. Cadmium metal coating functions as the sacrificial coating and erodes before the substrate material.

Natural Lubricity

This property of cadmium plating makes it a perfect choice for metal coating of bolts, anchors and moving parts of machines. It reduces the friction and improves the lubricity. Hence, reduces the wear and tear of machine parts. Its low coefficient of friction and galvanic compatibility with aluminum prevent galling of machine parts.

Electrical Conductivity

Low resistance and exceptional electrical conductivity of cadmium make it ideal metal coating for electrical wiring and connectors. It allows highly efficient transfer of electrical charge. Hence, it does not impact the functionality of the base metal and protects it from the external attacks.


Cadmium metal coating is a versatile product. Its special characteristics serve many needs simultaneously. Cadmium plating on any material forms a thick layer of metal coating that can be used to protect substrate in any conditions. Also, it works really well as paint or paint base. When used as finishing ( https://www.sun-glo.com/blog/ ), this material can be dyed to a large number of colors to achieve desired results and provides the perfect finishing.

These are the key benefits of the cadmium plating.

So, if you are also looking for the metal coating options for harsh climatic conditions, cadmium plating is one of the best metal plating.
