Anodization

What is anodization?

Anodic oxidation is the electrochemical oxidation of metals or alloys. The process in which aluminum and its alloys form an oxide film on aluminum products (anodes) under corresponding electrolytes and specific process conditions due to the action of applied current. Anodizing, unless otherwise specified, usually refers to sulfuric acid anodizing.

Which material can be anodized?

Anodizing of aluminum alloys is quite common and can be applied in daily life. Due to the characteristics of this process, a hard protective layer is formed on the surface of aluminum parts, which can be used to produce daily necessities such as kitchenware. But the anodizing effect of cast aluminum is not good, the surface is not bright, and it can only be black. The effect on aluminum alloy profiles are much better.

What are the benefits of anodizing?

1. Anti-corrosion protection: Anodizing can form a dense and strong oxide layer on the aluminum surface, providing good corrosion resistance. This makes anodizing suitable for aluminum parts and products used in harsh environments, such as automotive parts, building materials, aerospace components, etc.

2. Decorative effect: Anodizing treatment can form an oxide layer of various colors on the aluminum surface, providing a decorative effect. This makes anodizing widely used in indoor and outdoor architectural decoration, furniture, electronic product casings and other fields to increase the beauty and texture of the product.

3. Improved insulation properties: The oxide layer after anodization has high insulation properties and can be used in electronic and electrical applications, such as electronic radiators, electronic component housings, electrolytic capacitors, etc.

4. Improved hardness: Anodizing treatment can significantly improve the surface hardness of aluminum. This makes anodizing suitable for applications requiring wear-resistant properties, such as automotive parts, motorcycle parts, industrial equipment, etc.

5. Dyeing and printing: The surface of the oxide layer after anodization can interact with dyes and inks, which can realize dyeing and printing on the surface of aluminum materials. It is suitable for products that require personalized processing such as logos, trademarks, patterns, etc.
