All anodized surfaces, except for those processed with chemical bleaching or mechanical pretreatment, have a缎面哑光 appearance.

(1) Natural

This is a transparent anodized film, showcasing the underlying metal's silvery luster. It is achieved by omitting the coloring stage in the process sequence and proceeding directly to anodization.

Anodizing processing

(2) Electric Color

A variety of colors from light bronze to black are produced. This is achieved by depositing cobalt or tin at the bottom of the holes in the anode membrane. The colors are created through optical effects, such as cobalt absorbing the blue elements of light that fall on the surface, resulting in the reflection of bronze. Since the coloring is obtained through optical effects dependent on the atomic particle size, there is no fading at all.

(3) Disturbance

This provides the most practical steel blue gray spectral range. It is the result of optical interference caused by nickel at the bottom of the expanded holes in the anode film. Similarly, due to the optical effect resulting from the particle size of the color, it is completely fade-proof.

(4) Combination

The combination of bronze shadows with lightfast organic dyes can achieve various shades of blue, red, turquoise, green, and orange. The coloring is fade-resistant, not completely fade-proof.
