Anodizing of aluminum profiles can be used in daily life. Due to the characteristics of this process, a hard protective layer is formed on the aluminum surface, which can be used to produce daily necessities such as kitchen supplies. However, the anodizing effect of cast aluminum is not very good, and the surface is uneven and only black and gray. Aluminum profiles are stronger. The following is a brief introduction to the aluminum sheet oxidation solution.
How To Deal With Oxidation Of Aluminum Sheets
In the past ten years, aluminum oxidation and coloring technology has made rapid progress in my country. Many factories have adopted new process technologies and accumulated sufficient experience in actual manufacturing. The anodizing process of aluminum and aluminum alloys has been perfected and developed, and the appropriate process can be selected according to specific manufacturing needs. Before choosing the oxidation process, we need to understand the raw materials of aluminum or aluminum alloy profiles. Because the difference in raw material quality and composition will directly affect the quality of aluminum products after anodization.
For example, if the aluminum surface has defects such as bubbles, scratches, peeling, and roughness, most defects will still occur after anodization. The alloy composition also affects the surface appearance after anodization.
For example, aluminum alloy profiles containing 1 to 2% manganese turn brown to dark blue after oxidation, and the surface color after oxidation changes from brown to dark blue to dark brown.
Aluminum alloy profiles containing 0.6 to 1.5% silicon turn dark gray after oxidation, while those containing 3 to 6% silicon turn white gray.
It shows milky color when containing iron, orange to dark gray when containing magnesium, and light yellow when containing nickel.
Generally speaking, only aluminum containing more than 5% magnesium and titanium can obtain a colorless, transparent, bright and clean appearance after oxidation.
After selecting aluminum and aluminum alloy materials from aluminum sheet manufacturers, of course you must consider choosing the appropriate anodizing process. At present, hydrochloric acid oxidation, oxalic acid oxidation and chromic acid oxidation are widely used in us.
8021 aluminum foil has the characteristics of cleanliness and hygiene, and can be made into an integrated packaging material with many other packaging materials. In addition, the surface printing effect of 8021 aluminum foil is better than other materials. Therefore, 8021 aluminum foil alloy can also be used in the field of food packaging.
7075 aluminum sheet is the strongest heat-treatable alloy, introduced by Alcoa in 1943, and can be heat-treated to achieve strength levels comparable to many steel alloys.
Compared with other alloy foils of series 1, such as 1060 and 1070 aluminum foils, the content of (Fe+Si) in 1100 aluminum foil is higher than both, and the content of Fe is the key factor to improve the strength and toughness
6061 aluminum sheet is an al-si-mg alloy that has been strengthened by precipitation hardening. 6061 aluminum has a high strength-to-weight ratio, above-average corrosion resistance, good machinability, and is well suited for welding.
If you are looking for top-quality prepainted aluminum coils with various alloy models and specifications, Huawei Aluminum is your ultimate choice.
Aircraft grade aluminum sheet is a type of aluminum alloy that is specifically designed for use in aerospace applications. These sheets are made from high-strength aluminum alloys that are lightweight yet strong enough to withstand the stresses and strains of flight.
