anodizing

Aluminum Anodizing Overview

Aluminum anodizing is a process that forms an oxide layer on the surface of aluminum parts, thereby improving their corrosion resistance, hardness, and wear resistance. This process utilizes electrochemical principles, where aluminum parts are used as the anode in an electrolyte solution containing appropriate electrolytes, and an external electric current is applied to oxidize them.

This oxide layer is typically composed of aluminum oxide (Al2O3) and possesses excellent corrosion resistance, hardness, and insulation properties.

About Aluminum Anodizing FAQs

Anodized aluminum can last for decades under normal conditions. Its durability is attributed to the protective oxide layer formed during the anodizing process, providing resistance to corrosion, abrasion, and fading. Proper maintenance and care can further extend its lifespan.

The duration of anodizing treatment depends on the size, shape, and quantity of the aluminum products being processed, as well as the desired thickness and color of the oxide layer. Generally, the processing time ranges from several minutes to several hours. We strive to minimize the processing time to meet the needs of our customers.

The cost of anodizing treatment depends on factors such as the size, quantity, processing complexity, and required color of the parts. We offer competitive pricing and strive to ensure that customers receive cost-effective services. Contact us for a quotation.

In essence, anodizing enhances the natural oxide layer on aluminum, providing additional protection against corrosion, wear, and other environmental factors. It also allows for the introduction of various colors through dyeing processes, improving the aesthetic appeal of the aluminum while maintaining its structural integrity.

We offer a variety of color options, including natural aluminum, black, gold, silver, and more. These colors can be achieved by controlling the formation of the oxide layer and the dyeing process.
