As a CNC machinist, you’re always looking for ways to make your parts production more efficient and cost-effective. You may have heard of nickel plating as one way to improve the performance of your machined parts.

But what exactly is nickel plating, and how does it benefit your production process? In this article, we’ll take a closer look at the properties and benefits of using nickel plating in CNC machined parts production.

Nickel plating has been used by designers and engineers for decades to provide superior corrosion protection on metal surfaces. It also offers a range of other benefits that can help you improve your parts production process in a variety of ways.

We’ll explore these advantages in detail so that you can better understand how they apply to your work as a CNC machinist.

What Is Nickel Plating?

Nickel plating is like a shiny armor for your CNC machined parts, protecting them from corrosion and wear. It's a chemical process that involves depositing a layer of nickel onto the surface of an item, usually steel or iron.

The nickel can be deposited by electroplating or autocatalytic processes. The nickel used in the plating process typically has a chemical composition of 99+% pure nickel.

The benefits of nickel plating go beyond just protection of your machined parts. It also provides enhanced resistance to abrasion and heat as well as improved electrical conductivity and improved lubricity.

Additionally, it is one of the most environmentally friendly metal finishing processes available today due to its low VOC (volatile organic compounds) emission levels. Nickel plating prevents corrosion and extends the life of machined parts while having minimal environmental impact- a true win-win situation!

Why Use Nickel Plating?

Why Use Nickel Plating

Using nickel plating on CNC machined parts is a great way to ensure part longevity and quality. Not only does it provide corrosion resistance, but also wear protection that extends the life of your parts.

Let's take a closer look at why nickel plating is such a great option:

  • Nickel plating provides superior resistance against rust and oxidation. This means your parts will last longer even in harsh environments.
  • It increases the durability of the part, making it less susceptible to damage from wear and tear over time.
  • The finish looks attractive and can be customized with different colors or textures to fit the design aesthetic of your project.
  • Nickel plating offers superior protection from abrasion, which can help protect delicate components from friction-related damage.

Nickel plating gives you peace of mind that your parts are protected from corrosion and wear, so you don't have to worry about them getting damaged or becoming obsolete quickly.

Plus, its attractive finish makes it an ideal choice for high-end projects that require a professional look without sacrificing performance and reliability.

In short, nickel plating is an excellent choice for any application requiring long lasting protection and aesthetic appeal.

Types Of Nickel Plating

When it comes to nickel plating in CNC machined parts production, there are two main types that you should know about: electroless plating and immersion plating.

Electroless plating is a process that works without using electric currents. It deposits a uniform coating of nickel onto the part's surface by immersing it into an autocatalytic solution. This type of nickel plating is great for providing corrosion protection and maintaining dimensional integrity with consistent thicknesses on complex shapes and hard-to-reach areas.

On the other hand, immersion plating uses an electric current to deposit metal onto the part's surface by immersing it into a bath of metal salts. This process generally provides better wear resistance and is able to achieve thicker coatings than electroless plating.

Immersion plating can also be used for decorative purposes because its smooth finish provides great visual appeal.

Overall, both types of nickel plating offer great benefits in terms of corrosion protection, dimensional accuracy, and thick coatings that can be applied to intricate parts with even coverage over difficult-to-reach surfaces. Nickel's many advantages make it an excellent choice for CNC machined parts production!

Advantages Of Nickel Plating

Advantages Of Nickel Plating

I love the way nickel plating adds a beautiful finish to CNC machined parts. Not only does it look good, it has some great properties that make it an excellent choice for production parts.

Nickel plating adds a layer of corrosion resistance and surface protection that can help extend the life of the part, giving you more bang for your buck.

Here are some other advantages of nickel plating:

  • It creates an aesthetically pleasing finish that won’t chip or crack over time
  • It is highly resistant to corrosion and oxidation, making it ideal for use in harsh environments
  • It helps protect against wear and tear due to its durability and scratch resistance

Nickel plating is an easy way to add a layer of protection to machined parts while also improving their visual appeal. Plus, its excellent corrosion resistance means you’ll get more use out of your parts before needing to replace them – saving time and money in the long run!

Disadvantages Of Nickel Plating

The use of nickel plating in CNC machined parts production can be deceivingly alluring due to its properties and benefits. However, it is important to consider the potential disadvantages of using this technique.

Myriad safety hazards and environmental impacts come into play when using nickel plating for CNC machined parts.

It goes without saying that nickel plating can cause harm to both people and the environment if not handled with great care.

Workers are at risk of skin sensitization and allergic reactions when exposed to the hazardous chemical compounds used in the process.

In addition, nickel is on the list of toxic substances released into the environment by industrial processes, with its waste products potentially polluting rivers, lakes and oceans.

Therefore, it is essential that safety precautions are taken and that disposal methods are carefully considered in order to minimize any negative consequences associated with nickel plating.

When used properly, nickel plating can be an effective method for finishing CNC machined parts but great caution must be taken in order to ensure its safe application.

Cost-Effectiveness Of Nickel Plating

Cost-Effectiveness Of Nickel Plating

I understand the importance of cost-effectiveness when it comes to nickel plating in CNC machined parts production. That's why I'm going to examine durability comparison and environmental impact to determine how cost-effective nickel plating is.

Durability comparison is an important factor when discussing cost-effectiveness. Nickel plating offers increased resistance to corrosion, wear, and abrasion, making it a more durable option than other finishes. This means that the need for repair or replacement of parts can be greatly reduced, leading to decreased costs over time.

On the environmental side, nickel plating is also advantageous in terms of sustainability. It uses fewer chemicals during the process and produces less waste material than other finishes. As such, there are fewer hazardous substances released into the environment during production, leading to improved air quality and safety standards.

In light of these factors, it is clear that nickel plating offers increased cost-effectiveness compared to other finishes when it comes to cnc machined parts production. With greater durability and a lower environmental impact, the benefits are obvious and undeniable.


In conclusion, nickel plating can be a great addition to CNC machined parts production. It has many advantages, such as cost-effectiveness and improved durability.

However, it is important to keep in mind that there are a few drawbacks as well, such as the need for regular maintenance and the potential for surface damage if not properly protected.

By weighing all of these factors, you can make an informed decision that will help ensure that your CNC machined parts are protected in the best way possible.
