Anodizing services are considered the process of increasing the natural oxide layer of a metal part to resist corrosion and wear. This is done by converting the metal surface into a decorative, durable finish. Despite the complexity of anodizing, the process is relatively simple.

To do so, the metal part is immersed in an electrolytic solution along with a cathode. A current is then passed through the electrolytic solution. As a result, the cathode releases hydrogen and oxygen forms on the surface of the anode. Lastly, the treated surface forms a metal oxide film that enhances the appearance and durability of the metal part. As foreign of a concept as anodizing sounds, the process is actually used in many everyday items. For example, refrigerators, microwaves, golf carts, baseball bats, electronics, all use anodizing.

Metalphoto Processing

Anodized aluminum is also found in metalphoto processing. This material can often be found in high-resolution control panels, labels, barcodes that can be read by machinery, nameplates, and more. Metalphoto is extremely durable, as it can withstand all elements of wear and tear. Metalphoto is also flame-resistant, scratch-resistant, anti-counterfeit features,  and can print serial barcode numbers for encrypted data.

Specifications that Metalphoto processing meets include:

  • MIL-STD-130

  • MIL-STD-129

  • MIL-DTL-19834

  • MIL-DTL-43719

  • MIL-DTL-15024

  • MIL-SPEC GGP-455

Benefits of Anodizing

So, what are the benefits of anodizing? By restoring a metal part through an anodizing finish, its lifespan can extend to 20 years. Especially for metals of heavy use, anodizing increases its longevity. This is done by protecting against damage from sunlight, harsh chemicals, or physical contact’s daily wear and tear. The oxide layer also provides a better surface for the adhesion of paints and glues than bare metal. When anodizing, it is also important to consider the thickness of the coating as well as the quality of the anodic coating process. The main rule of thumb is the thicker the layer, the longer it’ll last. It is also important to consider that the coating is relatively thin compared to paints and powders, yet is more hard and durable. Not to mention, its environmentally friendly finish can be recycled and is inexpensive compared to other coating methods.
