Coloring ways for colored aluminum sheet metal - Aawpltgl - 08-12-2020
<div>
A <strong>colored aluminum sheet metal</strong> is developed in order to improve the abrasion resistance and enhance the decorative effect of the sheet surface. Oxidization and coloring on the surface not only makes an aluminium plate more corrosion resistant and endurable, but also helps to save costs efficiently. </div>

Before being colored, an aluminum sheet should first be oxidized. The full name for the process is anodic oxidation, which is process of generating an oxide film on aluminum alloy sheets (functioning as the anode) under the corresponding electrolyte and specific process conditions due to the applied current under the corresponding electrolyte and specific process conditions. The functions of anodizing process are to strengthen hardness and rust resistance of the sheets surface. Following the anodizing process, the coloring process can be carried out in three ways.<br>
</div>
<div>
</div>
<div>
1. Chemical coloring: An aluminum plate that has undergone the oxidation treatment is immersed in an organic or inorganic dye solution, and the dye penetrates into the pores of the oxide film to undergo chemical or physical action to be colored. Chemical coloring is simple in operation, low in cost, and rich in color, but has poor light and corrosion resistance, mostly used for interior decoration.</div>
<div>
</div>
<div>
2. Electrolytic coloring: The oxidized aluminum plate undergoes a secondary electrolysis in a single metal salt or multiple metal salt aqueous solution. Under the action of an electric field, aluminum cations penetrate into the pores of the oxide film and are deposited on the bottom of the pores, thereby the oxide film produces bronze, brown, gray, and red, cyan, and blue hues.</div>
<div>
</div>
<div>
3. Natural coloring: This is a method for coloring aluminum sheets during anodizing. There are alloy color method and solution color method. The former is to control the composition of aluminum alloys to obtain different color tones, and the latter, also called electrolytic coloring method, controls the color of electrolyte components and electrolytic conditions. In actual production, natural coloring generally uses organic acids as the electrolyte, and a small amount of sulfuric acid is added to adjust the pH.</div>

In these ways, a plain aluminum sheet turns into a <strong>decorative aluminium sheet</strong> of desired color. Haomei supplies colored aluminum sheet metals of 1xxx, 3xxx and 5xxx series. Welcome to contact us!</div>

Pre-painted Finishes offer extreme durability in outdoor exposure as well as indoors because of our high-quality paint system. Pre-painted aluminum sheet finishes are uniquely designed in that they offer a hard, abrasive resistant coating, yet allow the flexibility for extensive forming and fabricating. Our painted sheets are manufactured of 3105 H-14 Aluminum. 3105 Aluminum is an essentially 98% pure aluminum alloy with minor additions for strength. It is not hardenable by heat treatment. Corrosion resistance, formability and welding characteristics are excellent. It is commonly used for sheet metal work in in the manufacture of race cars, residential siding and mobile homes. Weldability of this alloy is excellent by all commercial techniques. Arc welding is preferred for the best results.
