Speaking of aluminum sheets, many users are familiar with 1050 aluminum sheet plate and 1060 Aluminum plate, but for the difference between them, there is not much understanding. Let's talk to you about the difference between 1050 aluminum plate and 1060 aluminum plate?
1050 aluminum sheet
In fact, these two kinds of aluminum plates are a series of aluminum plates, but the aluminum content is different. The aluminum content of 1050 aluminum plate is 99.50%, and that of 1060 Aluminum plate is 99.60%. Just look at the last two. Relatively speaking, the higher the aluminum content is, the softer the material is, but there is little difference between the two. It can not be strengthened by heat treatment. 1060 is suitable for stretching and other products.
1060 aluminum sheet
Aluminum and its alloys will be oxidized in air. The oxide film formed naturally on the aluminum surface is amorphous, which will make the aluminum surface lose its original luster. Although this layer of natural oxide film will slightly passivate the aluminum surface, it is very thin, about 4-5nm, with large porosity and poor mechanical properties, It can not effectively prevent the further corrosion of aluminum by various media in the atmosphere. After anodizing, a dense film (from tens of microns to hundreds of microns) can be obtained on the surface of aluminum and its alloys. After sealing treatment, the amorphous oxide film is transformed into crystalline oxide film, and the pores are sealed. Therefore, the luster of the metal surface can remain unchanged for a long time, the corrosion resistance and mechanical strength are improved, and the decorative appearance can be obtained after dyeing. Aluminum and its alloy products have many characteristics after anodizing, so aluminum anodizing process is widely used in surface treatment of aluminum products. The industrial applications can be divided into the following categories:
(1) Prevent corrosion of products
Due to the proper sealing treatment, the film obtained by anodic oxidation has good stability in the atmosphere. No matter from sulfuric acid solution, oxalic acid solution or chromic acid solution in the normal process, the corrosion resistance of the oxide film is very good, such as daily aluminum pot, pot, washing machine liner, etc. Chromic acid oxidation method is especially suitable for aluminum welding and riveting parts.
(2) Protection decoration
On the oxide film with high transparency, the oxide film can absorb a variety of organic dyes or inorganic pigments, and a variety of bright colors and patterns can be obtained on the oxide film. In addition, the emergence of many new processes in recent years, such as one-time oxidation and multiple coloring, fireworks pattern, wood grain pattern, oxidation offset transfer printing, porcelain oxidation, etc., make the appearance of aluminum more beautiful and pleasing, This layer of color film is not only a decorative layer, but also an anti-corrosion layer, such as lighters, gold pens and handicrafts.
