Alumite processing

Alumite processing

Enhancing corrosion resistance and wear resistance! Surface treatment of aluminum using anodizing.

Anodizing (anodizing process) refers to "surface treatment by the anodic oxidation method of aluminum." A porous and transparent oxide film is generated electrolytically on the surface of aluminum, creating a layer from the outer surface into the interior, which enhances the hardness of the aluminum coating as well as its corrosion resistance and wear resistance. Additionally, by adsorbing inorganic and organic dyes onto the surface of the generated film, it is possible to express an infinite range of colors. 【Features】 ■ Increased hardness ■ Improved corrosion and wear resistance ■ Enhanced dyeing and coloring properties *For more details, please refer to the external link or PDF materials, or feel free to contact us.

Information on the anodizing process

Information on the anodizing process

Artificially make the natural oxide film harder and more resistant to corrosion! Introducing the process of anodizing treatment.

We would like to introduce our anodizing processing procedure. The first step in the electrolytic treatment of aluminum products is a very important task known as "racking," which plays a crucial role. After this is completed, the items undergo anodizing, which is the key process in the overall procedure. Following that, in the "quality inspection" process, we check each finished product one by one to ensure there are no defects. We identify various issues such as scratches, dents, color unevenness, and anodizing burns, and carefully sort them. 【Processing Steps】 ■ Racking ■ Anodizing ■ Quality Inspection *For more details, please refer to the PDF document or feel free to contact us.

[Column] What is anodizing?

[Column] What is anodizing?

A detailed explanation of the characteristics and processing mechanisms, as well as the differences from plating!

Anodizing is a treatment that artificially thickens the oxide film that forms on the surface of aluminum, making parts and products resistant to rust and wear. Additionally, by pouring metal into the countless small holes that occur during the anodizing process, it is possible to impart magnetic properties to aluminum and increase its strength. This article will provide a detailed explanation of what anodizing is and the methods of treatment. [Contents] ■ What is anodizing? ■ Methods of anodizing ■ Aluminum alloys that are difficult to anodize ■ What is colored anodizing? ■ Differences between anodizing and plating ■ Questions regarding anodizing *For more details, please refer to the PDF document or feel free to contact us.
