Aluminum Background:

Aluminum profile refers to aluminum alloy profile. Aluminum profile products are characterized by flexible design, hardness, light structure and wear resistance, which make them suitable for a variety of different uses. For the transportation industry, the lightness of aluminum alloy greatly saves the energy consumed during acceleration and deceleration, while its high wear resistance helps to save maintenance costs. In other industrial fields, such as power equipment, mechanical equipment, aerospace, infrastructure construction, etc., its application is also being promoted continuously; At the same time, aluminum profile products are also beautiful and practical building materials, which are easy to assemble, install, paint or combine with other materials. Aluminum is harder than many other materials, and can be used for door and window frames and outdoor curtain wall materials. It can also be added to the building structure to consolidate and protect.

First of all, from the production of aluminum profiles in China, according to the statistics of China nonferrous metal processing industry association, the output of aluminum profiles in China showed an increasing trend from 2016 to 2020. In 2020, China produced a total of 20.2 million tons of aluminum profiles, an increase of 6.6% year on year.

According to the output of segmented products, the output of China's construction aluminum profiles in 2020 accounted for about 69.43%, and the output increased by 5.7% compared with that in 2019; The output of industrial aluminum profiles accounted for about 30.57%, with an increase of 8.7% compared with 2019. Among the subdivided products of industrial aluminum profiles, the output growth rate of photovoltaic profiles is 42%, making it the largest subdivided category of industrial aluminum profiles.

Oxidation Types:

1. Chemical oxidation

At a certain temperature, a thin oxide film is formed on the surface of aluminum alloy profile through chemical reaction, which is called chemical oxidation of aluminum. This method does not need to pass through current, and the process is simpler and cheaper than electrochemical oxidation. The oxide film is very thin, and the film thickness is 0.5~4 μ M or so, the film is soft and has low wear resistance, so it cannot be used alone. The film has good physical adsorption capacity and is a good primer. The protective layer obtained by chemical oxidation can greatly improve the protective ability of parts.

2. Anodic oxidation method

Anodizing of aluminum alloy profile is made by electrolysis in oxalic acid, sulfuric acid and chromic acid aqueous solution with aluminum or aluminum alloy as anode and lead, carbon or stainless steel as cathode. Electro anodic oxidation can obtain film-forming speed that is difficult to obtain by natural oxidation. In the process of oxidation film formation, two processes occur at the same time: one is the formation of Al2O3 oxide film on the surface of aluminum plate; Second, the formation process of oxide film is accompanied by the dissolution of oxide film. Only when the formation rate of the oxide film exceeds its dissolution rate can a certain thickness of the oxide film be obtained, and the thickness of the film is generally 5~15 um. The film is a double-layer structure consisting of a dense barrier layer and a porous layer with a columnar structure. Anodic oxidation films of aluminum alloy profiles can be divided into two categories: porous films formed in acid electrolyzers such as sulfuric acid and oxalic acid, forming micropores perpendicular to the surface; Barrier film is a porous and extremely thin film formed in electrolyte, such as ammonium borate, which is commonly used in electrolytic capacitors.

Anodized Aluminum Profiles:

Aluminum alloy profiles are used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction and decoration. And chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts is increasing, which makes the research on the weldability of aluminum alloy go deep. The wide application of aluminum alloy promotes the development of aluminum alloy welding technology. At the same time, the development of welding technology expands the application field of aluminum alloy. Therefore, the welding technology of aluminum alloy is becoming one of the research hotspots.

It is easy to process and can be made into various profiles and plates with good corrosion resistance; However, the strength of pure aluminum is very low and it is in annealed state σ B value is about 8kgf / mm2, so it should not be used as structural material. Through the long-term application of aluminum elements and heat treatment, people have gradually strengthened this series of aluminum alloys. The alloy formed by adding certain elements can not only keep the advantages of pure aluminum light, but also have high strength, σ B values can reach 24 ~ 60kgf / mm2 respectively. This makes it "specific strength" (the ratio of strength to specific gravity) σ B/ ρ) It is better than many alloy steels and becomes an ideal structural material. It is widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry. The fuselage, skin and compressor of aircraft are often made of aluminum alloy to reduce self weight. Using aluminum alloy instead of steel plate welding can reduce the structural weight by more than 50%.
