Regular anodized (white)

It is applicable in various fields. Unlike painting, it does not have the effect of hiding scratches or dirt. In fact, it may make scratches and dirt more noticeable.
Anodizing success depends on the quality of the aluminum. If the original aluminum lacks shine or has noticeable stains, anodizing will not bring out the shine or remove the stains.


Examples of use

* Coating thickness (μm)

Hardness (HV)

Vehicle parts, window frames, sashes.

5~30

350

* Coating thickness may vary depending on size, shape, and material.

Colored anodized

This material is employed in various industries for aesthetic applications, including computer components and motorcycle parts. Unevenness in the material is not noticeable with silver, but it may become noticeable when colored. The impression of the color may also vary slightly depending on the material.


■ Black
■ Please contact us for red, blue, and gold colors.
