Cadmium plating plays a crucial role in aerospace and military operations, ensuring the reliability and longevity of critical components. New Method Plating specializes in cadmium plating services, providing the precision and dependability that aerospace and military plating applications require. Learn more about cadmium plating and how it contributes to the safety and longevity of essential components in these industries.

What Is Cadmium Plating?

Cadmium is a soft, silvery metal that resists corrosion and chemical damage. Manufacturers can add cadmium plating to aluminum, brass, copper, iron, or steel parts to create a smooth, uniform layer on surfaces. Some of the positive characteristics cadmium plating offers include:

Good bonding with other metals
Lubricity
Ductility
Chemical and corrosion resistance
Solderability

These qualities make cadmium plating an ideal coating for metal bolts and other fasteners, military parachute buckles, aerospace galvanic couplers, and more.

The Role of Cadmium Plating in Aerospace and Military Applications

Cadmium plating is extensively used in aerospace and military applications due to its protective properties. It can make metal components last longer in harsh environments, reducing the need for replacement and repairs that can complicate missions. Take a closer look at how cadmium plating can make components more functional and effective over the long term.

Corrosion Protection

Cadmium naturally resists corrosion, even in marine environments with exposure to salt water. Cadmium plating creates a corrosion-resistant shield around metal parts so the chemicals can’t reach the vulnerable metal underneath. This protects defense and aerospace components from chemicals, reducing the need for frequent replacements or unscheduled downtime.

Wear Resistance

Cadmium plating also resists physical wear and tear. It allows gears and bearings to handle repeated movement and heavy loads without showing deformation. In aerospace applications requiring precision, cadmium plating’s high wear resistance also helps maintain components’ structural integrity.

Electrical Conductivity

Electrical systems and components in demanding aerospace environments can face exposure to extreme temperatures during operation. High temperatures can cause these to overheat and malfunction. Using cadmium plating on electrical components enables better electrical functionality and can improve system efficiency.

Low Toxicity

Cadmium can be unsafe in large volumes or with long-term exposure. However, using cadmium plating offers relatively lower toxicity risks. This option allows aerospace manufacturers to produce safer goods while still harnessing the positive effects of cadmium.

Lightweight Quality

In the aerospace industry, minimizing weight requirements is key to many designs. Manufacturers can produce lighter-weight components by plating lighter metals with cadmium, reducing the total weight of assemblies and vehicles. This lighter-weight solution also increases speed and maneuverability.

Efficiency

Cadmium plating improves the reliability of electrical systems. This is crucial to maintaining safety and minimizing downtime. It also prevents system or component issues for end users.
