Marking Anodized Aluminum

When engraved or marked with either a CO2 or fiber laser system, anodized aluminum produces a high-quality, high-contrast, permanent mark.

What is anodizing?

Aluminum that’s been anodized has gone through an electrochemical process that increases durability and resistance to corrosion and wear. It is not treatment that is painted on or applied, it is actually grown from the metal itself. This process can be done on a variety of metals, but works particularly well on aluminum.

The anodized layer of aluminum is actually white, but after the process is complete the product can be dyed just about any color, which makes it ideal for a variety of products.

How does anodized aluminum react with the laser?

When laser engraving anodized aluminum with a laser, you’ll notice a bright contrast. That’s because when the laser beam hits the aluminum surface it actually bleaches it to expose the anodized layer below. Laser marking anodized aluminum doesn’t impact the protective qualities of the anodized layer, and it doesn’t impact the structural integrity of the product either.

Whether you are laser etching serial numbers, logos, or other text/graphics, Epilog’s high-speed machines provide a high quality on all of your anodized aluminum products.

What types of anodized aluminum products
can you mark with your Epilog?

Anodized aluminum is very durable, lightweight, and relatively inexpensive. It’s also very versatile and can be found in a variety of industries. Therefore, it’s used widely in the world of manufacturing. Anodized products commonly marked with a laser include:

Skilte

Anodized aluminum is lightweight, but very durable, making it perfect for indoor/outdoor signage, point of purchase displays, directional signage, and much more.

Elektronik

Often referred to as “tech tattoos”, you can use your laser machine to add a serial number, logo, or personal message/quote on all kinds of electronics that are commonly made of anodized aluminum, such as mobile phones, tablets, and laptops. The laser moves at such a high speed and low power that internal components of the device are not compromised.

This application is great for not only branding, but it also helps companies keep track of their assets and deters theft.
