鋁合金型材/ Aluminum alloy profile

鋁合金型材在航空、航天、汽車、機械制造、船舶，建筑，裝修及化學工業中已大量應用。隨著近年來科學技術以及工業經濟的飛速發展，對鋁合金焊接結構件的需求日益增多，使鋁合金的焊接性研究也隨之深入。鋁合金的廣泛應用促進了鋁合金焊接技術的發展，同時焊接技術的發展又拓展了鋁合金的應用領域，因此鋁合金的行業運用更加廣泛。

Aluminum alloy profiles have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, 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, so the research on the weldability of aluminum alloy is also in-depth. The wide application of aluminum alloy promotes the development of aluminum alloy welding technology, and the development of welding technology expands the application field of aluminum alloy, so the application of aluminum alloy industry is more extensive.

純鋁的密度?。é?2.7g/cm3），大約是鐵的 1/3，熔點低（660℃），鋁是面心立方結構，故具有很高的塑性（δ:32~40%，ψ:70~90%），易于加工，可制成各種型材、板材，抗腐蝕性能好；但是純鋁的強度很低，退火狀態 σb 值約為8kgf/mm2，故不宜作結構材料。通過長期的生產實踐和科學實驗，人們逐漸以加入合金元素及運用熱處理等方法來強化鋁，這就得到了一系列的鋁合金。 添加一定元素形成的合金在保持純鋁質輕等優點的同時還能具有較高的強度，σb 值分別可達 24～60kgf/mm2。這樣使得其“比強度”（強度與比重的比值 σb/ρ）勝過很多合金鋼，成為理想的結構材料，廣泛用于機械制造、運輸機械、動力機械及航空工業等方面，飛機的機身、蒙皮、壓氣機等常以鋁合金制造，以減輕自重。采用鋁合金代替鋼板材料的焊接，結構重量可減輕50%以上。

按合金成分可分為1024、2011、6063、6061、6082、7075等合金牌號鋁型材，其中6系的最為常見.不同的牌號區別在于各種金屬成分的配比是不一樣的，除了常用的門窗鋁型材如60系列、70系列、80系列、90系列、幕墻系列等建筑鋁型材之外，工業鋁型材沒有明確的型號區分，大多數生產廠都是按照客戶的實際圖紙加工的.

Pure aluminum has low density (ρ = 2.7g / cm3), about 1 / 3 of iron, low melting point (660 ℃), face centered cubic structure, so it has high plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), easy processing, and can be made into various profiles and plates with good corrosion resistance; however, pure aluminum has low strength, and its annealing state σ b value is about 8kgf / mm2, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually strengthen aluminum by adding alloy elements and using heat treatment methods, which leads to a series of aluminum alloys. The alloy formed by adding certain elements can maintain the advantages of pure aluminum, such as light weight, but also has high strength, σ b values can reach 24-60kgf / mm2. In this way, its "specific strength" (the ratio of strength to specific gravity σ B / ρ) 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 the self weight. The structure weight can be reduced by more than 50% by using aluminum alloy instead of steel plate.
