Anodized Aluminum Colors: Coloring Aluminum Products
With the wide application of aluminum alloy parts, CNC machining of aluminum alloy is becoming more and more popular. But aluminum alloy is easy to cause a chemical reaction with oxygen, so generally needs to do metal surface treatment, and anodized aluminum parts are the most common kind of metal surface treatment.
Why Do Aluminum Alloy CNC Products Often Do Oxidation Surface Treatment?
<![if !supportLists]>1. <![endif]>The aluminum alloy itself is a kind of raw material with strong corrosion resistance, but when it encounters oxygen, it generates oxidation on the surface of the aluminum alloy, and gradually eliminates its corrosion resistance and bran resistance for a longer period of time. In addition, aluminum alloys are very sensitive to acids. When it encounters acidity, it destroys the surface layers of aluminum. Then we need to oxidize again and add another layer to the surface layer to improve the surface corrosion resistance of the anti-corrosion protective film.

Oxidation film after boiling water, high-temperature water steam or nickel salt closed processing, can further improve its corrosion resistance and wear resistance.
