Matte White
Matte white is a surface‑finishing process in which aluminum is first treated with an acidic sandblasting etchant and then subjected to anodizing. This produces a highly uniform, densely pitted matte finish, while forming a transparent, hard oxide layer that exhibits a distinctive, finely matted silver sheen—offering both aesthetic appeal and excellent corrosion resistance.
Advantages of matte oxidation:
1. Low aluminum consumption, typically only 5–15 kg/t.
2. Effectively mitigates defects such as coarse grains and weld lines.
3. Sludge in the bath is easy to handle.
4. The matte, sanded finish has a strong metallic sheen.
5. Production operations are relatively safe.
