What is Industrial Anodizing?

What is Industrial Anodizing?

The process of anodizing is one of controlled oxidation of the underlying metal, which is usually aluminum. Through this process, the aluminum effectively gains a durable, corrosion-resistant coating which is fully bonded with the pure metal, as it is formed from the outer surface of it.

What is the Anodizing Aluminum Process?

The process of anodization involves soaking the aluminum in an acid electrolyte bath, at the same time as passing an electrical current through the bath. This process has the effect of causing oxygen atoms to be released from the electrolyte bath and bond with the aluminum surface, which acts as the anode during the process. A cathode is also located in the bath.

Where to Get Aluminum Anodized?

Anodizing is a tricky process to get right, so most anodizing is usually done by a specialist metal finishing company such as us, here at Secoa Technology LLC. Specialist companies have the right equipment and expertise to ensure that your anodizing is carried out correctly, giving you the tough, resilient surface you need for a wide range of different applications.

What Does Anodizing Aluminum Do?

The main benefits of oxidized aluminum are that the finished product is resistant to corrosion and is also extremely strong. Anodized aluminum is ideal for components that will be subject to weather extremes or chemical contamination. Because the anodized surface requires little maintenance, it is ideal for use on components which may be located in hard-to-reach places.

How Thick is an Anodized Coating?

The thickness of an anodized coating varies depending on the application: for example, usually a component that is being coated for good corrosion and chemical resistance is between 0.05 and 0.030 whereas if non-stick release is required, the thickness is usually 0.001 to 0.005. A good anodizing company will be able to coat within extremely narrow tolerances, consistently giving the accurate results required.
