When it comes to metal plating, there are a wide variety of options to choose from. Two of the most popular choices are nickel plating and cadmium plating, but what do you need to know about each process so that you can make an informed decision? Let’s have a closer look at the two processes and how they compare.
Nickel Plating
Nickel plating is often used as a protective layer on metal surfaces and to enhance the appearance of those surfaces. It is often applied with another metal, such as copper or zinc, which helps prevent corrosion, helps protect against abrasion, and increases the life span of the metal surface being treated. It also adds a pleasant aesthetic appeal to any product, making it ideal for decorative applications. The process is relatively simple and inexpensive compared to other metal plating processes.
Cadmium Plating
Cadmium plating is similar to nickel plating in that it provides a protective layer on metal surfaces; however, it does offer some distinct advantages over nickel plating. For one thing, cadmium-plated surfaces are much more resistant to wear and tear than nickel-plated surfaces; this makes them ideal for use in areas where high levels of friction may be encountered (such as moving parts). Additionally, cadmium has excellent electrical conductivity properties; this makes it an ideal choice when electrical components are involved in your product design. While the initial cost of cadmium plating may be higher than nickel plating, its long-term benefits typically outweigh its short-term costs.
Difference Between Nickel Plating and Cadmium Plating
- Nickel plating is more resistant to corrosion than cadmium plating.
- Nickel plating is more resistant to wear and tear than cadmium plating.
- Nickel plating is more resistant to high temperatures than cadmium plating.
- Nickel plating is more resistant to chemicals than cadmium plating.
- Nickel plating is less toxic than cadmium plating.
- Nickel plating is more environmentally friendly than cadmium plating.
Conclusion:
Both nickel and cadmium have their pros and cons when it comes to metal plating applications. Nickel is generally considered to be less expensive upfront but offers less protection in terms of wear resistance when compared to cadmium. On the other hand, cadmium provides greater levels of protection against wear and tear and excellent electrical conductivity properties, making it ideal for certain types of products or components. Ultimately, which one you choose will depend on your needs, so be sure to carefully weigh up all your options before making a decision!
