Anodized Coating

Aluminum is a light, durable and economical metal used in many industries today. Aluminum naturally oxidizes, forming a protective layer on its surface. However, this layer may not provide adequate protection in some environments. In this case, it may be necessary to do an extra treatment on the surface of the aluminum. This is where anodized coating comes into play. Anodizing is a coating method that oxidizes the surface of aluminum electrolytically, forming a thicker, harder and more durable layer. Anodized coating prolongs the life of aluminum products, makes them more aesthetically attractive and is an environmentally friendly process.

Anodized coating is a coating method used to protect the surfaces of aluminum and aluminum alloys and to increase their durability. This method is accomplished by electrolytic coating of the naturally occurring oxide layer of aluminum. Anodized coating has many benefits.

Protects the surface against scratches, wear and corrosion.
Makes the surface suitable for dyeing and printing processes.
Environmentally friendly and non-toxic process.
It insulates aluminum very well.

Anodizing is done by immersing aluminum in an electrolyte such as sulfuric acid or oxalic acid and applying an electric current. It is ensured that the aluminum changes as the anode. For this reason, anodizing is also known as anodizing.

Which metals are anodized coating applied to?

Aluminum is ideal for anodizing due to its structure. It is by far the most common due to its high strength, low weight and availability. Other metals such as magnesium, titanium and stainless steel can also be anodized.

How Long Should the Anodizing Thickness Be?

Anodizing thickness is determined according to national standards and atmospheric conditions. In general, a layer thickness of at least 5 microns is required for indoor applications and at least 15 microns for outdoor applications.

What are the Usage Areas of Anodized Coating?

Anodized coating is preferred in many industries where aluminum products are used. For example:

  • Defense Industry

  • Household products

  • Commercial and residential building products

  • Lighting fixtures

  • Cooling elements

  • Food preparation equipment

  • Sports equipment

  • Motor vehicle components

  • Jewelry and works of art
