There are many different types of metal finishing; some of the most popular are anodizing, painting, and powder coating. Choosing the right type of coating for your application can be essential to achieving the desired results. If you have a piece of metal that needs to be coated, you may find yourself wondering, “Which is best? Anodizing, painting, or powder coating?”
Anodizing
Anodizing is an electrochemical process that can be used to form a protective coating of oxide on a metal surface. One thing that sets anodizing apart from other finishing methods is that the coating it creates is actually a part of the metal, so it cannot peel or flake. As a result, anodizing makes metal surfaces extremely durable. Anodizing is great for applications that require high levels of corrosion resistance and abrasion resistance. Anodizing also makes metal surfaces non-conductive, which can be useful in certain circumstances. In most cases, anodizing is restricted to aluminum substrates only.
Powder Coating
Powder coating is a metal finishing process that involves applying dry powder to a metal surface, and then heating the powder until it cures. There are several reasons one might choose powder coating as a metal finishing method. Though powder coated surfaces are generally not as durable as anodized surfaces, they are still extremely resistant to corrosion, abrasions, and general wear and tear; powder coating is a quick and simple process, which makes it convenient; and powder coating comes in a huge variety of colors.
Painting
Using wet paint is the most conventional metal finishing method. Though paint is much less durable than powder coating or anodizing, it does have its advantages. For example, paint can be used to coat surfaces that can’t be heated; it comes in an even more impressive array of colors than powder coating; and it is often very affordable.
The Verdict
So, which is best: anodizing, painting, or powder coating? Well, the answer is that there is no clear answer. Each of these finishing methods is best for its own specific range of applications. If you need extreme durability, you may want to look into anodizing. If you need corrosion resistance, but you also want a lot of color choices, powder coating may be your best option. If you just want a classic coating that is simple and cost-effective, painting is the way to go.
