profile accessories are one of the important components of the aluminum profile
frame structure. When assembling various aluminum profile products, you must also use the matching aluminum profile accessories. The matching has a great impact on the quality of aluminum profile products. When we choose aluminum fittings, we must put forward higher requirements for its quality. Then, what are the industrial aluminum fittings? What are the quality requirements for aluminum fittings? 1. Profile corner fittings: Profile corner fittings are cut into angle pieces with the same size as the profile according to the model of the aluminum profile. They are used to connect various angles between the profile and the profile, which can play a supporting role. According to the different angles, they can be divided. It is a profile corner piece (right-angle connection), a 45 degree profile corner piece, and a 135 degree profile corner piece. The material of the profile corner pieces is the same as the 6063 extruded profile. The specific alloy formula is shown in the following table: Magnesium Mg Copper Cu Zinc Zn Silicon Si Manganese Mn Chromium Cr Titanium Ti Iron Fe Other elements Al 0.2-0.6≤0.1≤0.10.2- 0.6≤0.1≤0.1≤0.1≤0.35≤0.15 allowance; size: length and width can be cut according to demand, and the length can reach 6m. The specific size is related to the model and size of the profile. The commonly used profile angle pieces are 7070, 7878, 8080, angle: 90°, 45°, 135°. 2. Cast aluminum corner fittings: Cast aluminum corner fittings are made of cast aluminum alloy, and there are many types of them. The chemical composition of commonly used cast aluminum corner fittings is shown in the following table: Carbon C Silicon Si Zinc Zn Phosphorus P Sulfur S Manganese Mn Chromium Cr Copper Cu Mo Ni V V Al ≤0.23≤0.50≤0.1≤0.035≤0.0350.9-1.5≤0.025≤0.025≤0.08≤0.30≤0.050.15-0.60, where chromium + nickel + copper +The content of molybdenum does not exceed 0.70. 3. Size: According to the model of the profile, the commonly used cast aluminum angle pieces are 2020, 2080, 3030, 3060, 6060, 4040, 4080, 8080, 4545. 4. Angle: 90. There are many common accessories for industrial aluminum profiles. The specifications and materials of each kind of accessories are different, and the connection methods are also various. Aluminum profile accessories manufacturers can choose suitable accessories according to the size. Build various frame structures and apply them in all walks of life. The above are the requirements for the quality of industrial aluminum fittings, hoping to help users better choose aluminum fittings products.
