铝合金型材/ Sus aluminum alloy profile

铝合金型材在航空、航天、汽车、机械制造、船舶，建筑，装修及化学工业中已大量应用。随着近年来科学技术以及工业经济的飞速发展，对铝合金焊接结构件的需求日益增多，使铝合金的焊接性研究也随之深入。铝合金的广泛应用促进了铝合金焊接技术的发展，同时焊接技术的发展又拓展了铝合金的应用领域，因此铝合金的行业运用更加广泛。

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.

纯铝的密度小（ρ=2.7g/cm3），大约是铁的 1/3，熔点低（660℃），铝是面心立方结构，故具有很高的塑性（δ:32~40%，ψ:70~90%），易于加工，可制成各种型材、板材，抗腐蚀性能好；但是纯铝的强度很低，退火状态 σb 值约为8kgf/mm2，故不宜作结构材料。通过长期的生产实践和科学实验，人们逐渐以加入合金元素及运用热处理等方法来强化铝，这就得到了一系列的铝合金。添加一定元素形成的合金在保持纯铝质轻等优点的同时还能具有较高的强度，σb 值分别可达 24～60kgf/mm2。这样使得其“比强度”（强度与比重的比值 σb/ρ）胜过很多合金钢，成为理想的结构材料，广泛用于机械制造、运输机械、动力机械及航空工业等方面，飞机的机身、蒙皮、压气机等常以铝合金制造，以减轻自重。采用铝合金代替钢板材料的焊接，结构重量可减轻50%以上。

按合金成分可分为1024、2011、6063、6061、6082、7075等合金牌号铝型材，其中6系的最为常见.不同的牌号区别在于各种金属成分的配比是不一样的，除了常用的门窗铝型材如60系列、70系列、80系列、90系列、幕墙系列等建筑铝型材之外，工业铝型材没有明确的型号区分，大多数生产厂都是按照客户的实际图纸加工的.

2. 散热器铝型材。

3.一般工业铝型材：主要用于工业生产制造用的，如自动化机械设备、封罩的骨架以及各公司根据自己的机械设备要求定制开模，比如流水线输送带、提升机、点胶机、检测设备、货架等等，电子机械行业和无尘室用得居多。

4、轨道车辆结构铝合金型材：主要用于轨道车辆车体制造。

5、装裱铝型材，制作成铝合金画框，装裱各种展览、装饰画。

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.

By alloy composition

It can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other alloy grades of aluminum profiles, of which 6 series are the most common. The difference between different grades is that the proportion of various metal components is different. Except for the commonly used door and window aluminum profiles such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other building aluminum profiles, there is no clear model distinction for industrial aluminum profiles, and most of them are produced Factories are in accordance with the actual drawings of customers processing

According to surface treatment

1. Anodized aluminum

2. Electrophoretic coating of aluminum

3. Powder sprayed aluminum

4. Wood grain transfer printing aluminum

5. Fluorocarbon sprayed aluminum

6. Polished aluminum (divided into mechanical polishing and chemical polishing, of which chemical polishing is the most expensive and expensive)

By purpose

1. Building aluminum profiles (divided into doors and windows and curtain walls)

2. Radiator aluminum profile.
