Production Line of Anodizing for High Silicon High Copper Casted Aluminum Alloy

The production line is for anodizing of high silicon high copper casted aluminium. It solves the problem that the high silicon high copper casted aluminum is hard to be anodized.

By adjusting the processing technology parameters, the thickness of the high silicon high copper casted aluminum anodized film can be above 30um, and the highest can be above 50um;

By adjusting the processing parameters, the hardness (Hv) of the anodized film layer can be 400-500;

It can be anodized in a wide temperature range of 10 ～ 20 ℃;

The oxidized film is hard and has excellent wear resistance;

It has excellent salt spray etching resistance and fastness to sunlight (UV resistance);

With proper post-treatment, the wear resistance of the film layer is further improved, the friction coefficient is greatly reduced, and the service life is longer;

There are two kinds of anodizing methods: sulfuric acid method and oxalic acid method. The process has broad applicability and stable oxidation;

A high degree of automation, simple operation, and stable quality.

The standard process of high silicon casted aluminum anodizing:
