What does the oxide film logo of industrial aluminum profiles mean?

The surface treatment of industrial aluminum profiles is to chemically or physically cover the surface of industrial aluminum profiles with a protective film, and different treatment methods and different thicknesses of protective films have different letter marks. Such as Al/Et · A ( S ) 10 · S Let’s first explain that Al is the chemical element symbol of aluminum; Et stands for electrochemical treatment; A (S) stands for sulfuric acid anodization; 10 stands for oxide film thickness of 10 μ; the last S stands for sealing treatment. In this way, it is very easy to understand. This is the film thickness of 10μ on the surface of aluminum alloy anodization. If it is followed by the letter CI, it means that it needs to be colored, followed by a color code, for example, BK is black.

We usually use the average film thickness as the film thickness standard for the production of industrial aluminum profiles or photovoltaic aluminum profiles.

AA10 means the average film thickness ≥ 10μ and the local film thickness ≥ 8μ

AA15 means average film thickness ≥15μ and local film thickness ≥12μ

AA20 means average film thickness ≥ 20μ and local film thickness ≥ 16μ

AA25 means the average film thickness ≥ 25μ and the local film thickness ≥ 20μ

The grade of electrophoretic film thickness of industrial aluminum profiles is replaced by three letters A\B\S

A represents the local oxide film thickness ≥ 9μ paint film thickness ≥ 12μ composite film thickness ≥ 21μ

B represents local oxide film thickness ≥ 9μ paint film thickness ≥ 7μ composite film thickness ≥ 16μ

S represents the partial thickness of oxide film ≥6μ, paint film thickness ≥15μ, composite film thickness ≥21μ

There is no such film thickness classification for fluorocarbon sprayed aluminum profiles. The thickness of powder coating aluminum profile layer shall not be less than 40μ.
