Why the building structure to use aluminum alloy

Aluminum alloy is the most economical and reasonable in the construction structure.
 
Construction industry is one of the three major markets of aluminum industry, the world's total output of about 20% for the construction industry, some of the industrial aluminum industry, the construction industry, the use of aluminum has accounted for more than 30% of its total output. In recent years, the product of building aluminum industry is constantly updated, and the application of new construction products, such as color aluminum, aluminum composite, composite doors and windows, aluminum alloy, etc., is increasing year by year. China has in industrial aluminum aluminum industry and civil architecture application aluminum alloy production of roofing, walls, doors and windows, and gradually extended to inside and outside decoration, construction formwork, have achieved good results.
 
Features and uses of aluminum and aluminum alloy, the maximum of the first weight is about 1/3, while the ratio of strength (intensity ratio and the ratio of the ratio) can be reached or exceeded the structural steel. Secondly, aluminum and aluminum alloy are easy to be processed into various shapes, which can be adapted to all kinds of connecting process, so as to provide favorable conditions for the construction of the most economical and reasonable cross section. Therefore, the use of aluminum alloy can greatly reduce the weight of the building, save the material industrial aluminum material, but also reduce the transport of components, installation workload, accelerate the construction progress. This has a more obvious effect on the economic effect of the mountainous and remote areas of the earthquake zone and traffic inconvenience. Aluminum and aluminum alloy, good corrosion resistance, high reflectivity of light and heat, good absorption performance, through chemical and electrochemical methods to obtain a variety of different colors. Therefore, the industrial aluminum industry is widely used in the industrial and civil building roofing, walls, doors and windows, frames, inside and outside the decorative board, ceiling, ceiling, railings, interior furniture, store containers, and the construction of templates, etc..
 
The size of the aluminum is -1.67 V, the chemical properties are very active, and the oxygen in the air to form a layer of dense oxide film, so in the ordinary air and clean water, aluminum has good resistance to erosion. But with steel or other metal materials in contact with industrial aluminum material will produce electrical erosion, in the wet environment and concrete, cement mortar, lime and other alkaline materials will produce erosion, and wood, clay, etc.. Therefore, it is necessary to carry out the appropriate anti-corrosion treatment.
 
The function of pure aluminum is low, and its use is limited. But by adding a small amount of one or several alloy elements, such as magnesium, silicon, manganese, copper, zinc, iron, chromium, titanium, etc., can be obtained with different functions of the aluminum alloy. Aluminum alloy and heat treatment, and further strengthened and hardened, the tensile strength of the great progress.
 
Construction products made from aluminum alloy industry. Usually first processed into forging products, casting products, as well as foil, plate, strip, pipe, rod, profile, etc., and then through the cold bending, sawing, drilling, assembly, painting and other processes and made.
