What is aluminum alloy profiles

Aluminum alloy profiles are the most widely used class of non-ferrous metal structural materials in the aerospace, aerospace, automotive, machinery manufacturing, shipbuilding, construction and decoration. And the chemical industry has been a large number of applications. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts is increasing, and the welding research of aluminum alloy is also deepened. The extensive application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy, so aluminum alloy welding technology is becoming one of the hot spots

Pure aluminum has a low density (ρ = 2.7g / cm3), about 1/3 of iron, low melting point (660 ℃), aluminum is a face-centered cubic structure, so it has a high plasticity (δ: 32 ~ 40% Ψ: 70 ~ 90%), easy to process, can be made of various profiles, sheet, corrosion resistance is good; but the strength of pure aluminum is very low, annealing state σb value of about 8kgf / mm2, it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually to join the alloy elements and the use of heat treatment and other methods to strengthen the aluminum, which got a series of aluminum. The addition of certain elements to form the alloy in maintaining the advantages of pure aluminum and other advantages can also have a high strength, σb values up to 24 ~ 60kgf / mm2. This makes its "specific strength" (the ratio of strength to specific gravity σb / ρ) is better than that of many alloy steels, making it ideal for structural materials, widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry. , Skin, compressor and other often made of aluminum to reduce their weight. Aluminum alloy instead of steel plate welding, structural weight can be reduced by more than 50%.
