How to distinguish the type of anodizing after CNC machining

Therefore, if you want to fully understand anodizing, all of these cannot be omitted:

1. Is the natural anodization of the workpiece the same as the anodization of the workpiece?

For these two words, literally, there does not seem to be much difference. However, from a professional perspective, the two are still very different.

Natural color anodization is achieved through electrolysis. In terms of color, it is known to retain color before oxidation. Anodization is the coloration of the oxide film after electrolysis has achieved its purpose. Therefore, the color will change significantly. In addition, the number of steps is greater than the number of anodizing services.

2. What is the thickness of the anodized film formed at normal temperature?

Anodization is performed at normal temperature, and the thickness of the formed oxide film is usually 5 to 15 microns, and the hardness is 200-400HV. The corresponding low-temperature oxidation (called hard oxidation) is different from anodization. Because in the thickness of the film, it can reach 250 microns.

3. Are anodized aluminum and electroplated aluminum alloy the same?

Although both anodized aluminum alloys and electroplated aluminum alloys have been surface-treated on aluminum alloy materials and are similar in form, they are fundamentally different. Due to anodization, it is not easy to fall off, and the environmental protection during processing belongs to the third level. Electroplating is easy to fall off, and the environmental protection during processing is first-class. Therefore, there are still many differences.

The CNC machining workshop provides 3-axis, 4-axis and 5-axis rapid precision CNC machining services, including milling, machining according to customer requirements, and can process metal and plastic machining parts with a tolerance of +/- 0.005 mm. Secondary services include CNC and conventional grinding, drilling, and die casting.
