Cerakote vs. Anodizing: Which is the Better Choice?

If you’re wanting to protect and enhance metal surfaces, you no doubt may have thought about anodizing. Cerakote and anodizing both have their place and use, but if you’re after the best balance of durability, colour options, and all-around performance, Cerakote stands out as the superior choice. Let’s take a closer look at both processes to see why.

What is Anodizing?

Anodizing is an electrochemical process that strengthens and protects metal surfaces, primarily aluminium and titanium. Creating a hard, corrosion-resistant layer that essentially becomes part of the metal itself. This method is widely used in aerospace, automotive, and industrial applications due to its durability.

Pros of Anodizing:

  • Provides a durable, wear-resistant surface
  • Doesn’t chip or peel since it bonds with the metal
  • Great for aluminium parts, especially in aerospace and industrial applications

Cons of Anodizing:

  • Limited colour selection, often resulting in inconsistent shades
  • Susceptible to fading and chalking over time, especially with UV exposure
  • Less effective on metals other than aluminium and titanium
  • The process involves hazardous chemicals, making it less environmentally friendly

What is Cerakote?

Cerakote is a coating that isceramic-based and applied to metals, plastics, and composites via a spray gun. Often oven cured but also air cured in some instances to form a hard, protective layer. This layer is very thin yet highly effective at resisting abrasion, corrosion, and chemicals. Unlike anodizing, Cerakote has a huge range of colour options as well as the ability to make a custom colour should the need arise.

Pros of Cerakote:

  • Unmatched Durability – Superior wear and impact resistance compared to anodizing
  • Wide Colour Selection – Over 200 custom colours available, offering endless design possibilities
  • UV Stability – Unlike anodizing, Cerakote doesn’t fade or chalk under sun exposure
  • Corrosion Resistance – Protects against rust, salt, and chemicals, making it ideal for marine and firearm applications
  • Versatile Application – Works on a variety of materials, including steel, aluminium, polymers, and even wood
  • Environmentally Friendly – Meets environmental standards without requiring hazardous waste disposal

Cons of Cerakote:

  • Can chip if applied improperly, but professional application ensures a long-lasting finish
  • Requires a curing process, meaning slightly longer turnaround times compared to anodizing

Why Cerakote is the Better Choice

Anodizing certainly has its strengths, particularly for aluminium applications, but the lack of many colour options or colour consistancy lets it down. It also won’t last as long as Cerakote. Cerakote not only provides a tougher, more resilient finish, but it also allows for complete customisation without the risk of fading.

When high-performance in hard wearing and corrosive environments is key Cerakote is the way to go. The fact that it will look better is a bonus. Whether you’re coating firearms, automotive parts, industrial tools, or marine equipment, Cerakote offers superior protection and aesthetics that anodizing simply can’t match.
