Aluminum alloy metal surface in a variety of heat treatment, mechanical processing, transportation and storage process, will inevitably be oxidized, resulting in a layer of uneven thickness of the oxide layer. At the same time, it is also susceptible to various oil pollution and adsorption of some other impurities. Because of this, the maintenance and management of aluminum alloy metal has become a worry for many people.
After the metal surface is contaminated by oil and adsorbates, a thin oxide layer will be formed on the surface, which can be used.Cleaning agent for aluminumCleaning, or with ultra-wave machine cleaning treatment. For severely oxidized metal surfaces and metals with thicker oxide layers, mechanical treatment should be carried out first, and then chemical treatment.
Generally, the treated or cleaned metal surface is highly reactive and easily contaminated by dust, moisture, etc. For this reason, the aluminum alloy surface should be glued as quickly as possible.

The storage period of aluminum alloy metal after different treatments is as follows:
(1) Wet sandblasted aluminum alloy, 3 days;
(2) Chromic acid-sulfuric acid treated aluminum alloy, 6h;
(3) Anodized aluminum alloy, 30 days;
(4) sulfuric acid treated stainless steel, 20 days;
(5) Sandblasted steel, 4h;
(6) Wet sandblasted brass, 8h.
