What’s So Special About Cadmium Plating?

Cadmium has been used for plating across industries especially for saltwater applications and aircraft manufacturing. It is a very robust material that can be used for coating other metallic surfaces.

Collective properties of cadmium make it a very special metal to use for plating applications. Here’s what is special about cadmium plating.

Cadmium plating is sturdy and offers robust protection to the metals underneath. It is resistant to corrosion and offers the same benefits when used as a coating material. It can make bolts and fasteners stronger for use in harsh conditions. For this reason, cadmium is popular to use defense and aviation industries. It acts as a protective barrier for steel. It offers anodic protection to the ferrous-based metals underneath such as steel. Cadmium and aluminum are share agreeable galvanic compatibility. So, no galvanic corrosion occurs when these two are used together.

It can even offer more protection when a coating of chromate conversion is applied on it. Chromate is used as supplemental coating material for cadmium plating.

Cadmium is superior as a plating material compared with other metals. It also retains the original attributes and appearance for a long time; resulting in continued superior performance for various applications.

Cadmium plating is also popular for use on bolts especially for outdoors. The bolts do not corrode even under harsh weather. It is used on bolts and fasteners required for industrial use as well.

Low or no corrosion means there is minimal risk of machine parts jamming or malfunctioning. The corrosion debris won’t collect inside the machines and adversely affect its performance if the components are coated with cadmium.

Cadmium plating reduces friction. It has the capability to improve lubrication properties of a surface when used as a coating. Use of cadmium plating is advantageous for moving machinery parts for this reason. It can keep metal surfaces that come in contact with each other in a machine free of friction. Extra lubrication improves the performance of machines and also keeps them safe. Due to its lubricity, repetitive dismantling of machine parts is possible as there is no friction to consider.

Cadmium plating increases adhesive properties of other objects. The coating of cadmium on any surface can make it more viable for adhesives used in aircraft manufacturing. It can improve the adhesion on any surface by making them bond well with adhesives used in industrial applications. It comes in extremely handy when manufacturing components to use in the aviation industry.

Cadmium plating can boost also solderability of a metal. If a metal is not viable for good soldering, use of cadmium plating can rectify it. It can be used for soldering with different metals and alloys.

Cadmium plating offers powerful electrical conductivity.  So, it can be used for various industrial applications. It can enhance the performance of metals that do not conduct electricity well. It can also add to the performance of metals that conduct electrical current well. Use of cadmium plating won’t impede the electric flow when used in industrial applications.

Cadmium plating can be used with different metals and alloys. Cadmium is very popular to use on steel substrates. It is also used extensively on aluminum, copper, iron, and brass. Cadmium plating bears the maximum impact of damage when coated on these metals and alloys. It can be used as a paint base for achieving superior results.

Cadmium plating is resistant to bacteria and mold. For this reason, it is extensively used in alkaline and marine applications. It is also used for many household applications as well precisely due to this property.

Cadmium plating is useful for many industries. Industries such as aerospace, automotive, and mining use cadmium for plating purposes extensively. It widely used to make components needed for the defense industry. Electronic industries also utilize components coated in cadmium quite a lot. Cadmium finds its use as a plating material in many offshore industrial applications. Its application ranges from small to large machines and related components such as connectors, chassis, fasteners, bolts, and many more machinery and industrial parts.

Properties of cadmium have made it impossible to replace it with other types of metal coating.
