Silver Anodized Aluminium Door Frame Metal Building Materials High Strength

6063 Silver Anodized Aluminium Door Frame Aluminium Profile Extrusion Metal Building Materials

Aluminum Window Door Profiles Features:

1. Light weight and high strength

Aluminum alloy materials are mostly hollow thin-walled composite sections, which are easy to use and reduce weight. The sections have high bending strength, and the doors and windows made of them are durable and have little deformation.

2. Good sealing performance

The aluminum alloy itself is easy to extrude, the cross section size of the profile is accurate, and the processing is accurate Sealing materials with good waterproof, elasticity and durability can be selected, such as rubber beads and silicone sealant. In terms of profiles, various sealing strip fixing grooves have been completed in the same extrusion process with the same section, creating favorable conditions for the installation of sealing materials.

3. Beautiful appearance

The aluminum alloy surface can be colored after anodic telephone treatment, and can be selected at will. It is bright and bright after oxidation. The window sash frame is large and can be inlaid with large area of glass, which makes the indoor light sufficient and bright, enhances the contrast between the virtual and real facades between indoor and outdoor, and makes the room more layered.

4. Strong corrosion resistance

Aluminum alloy oxide layer generally does not fade, fall off, is not easy to alter, is easy to maintain, and does not need maintenance

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%.
