Aluminum alloy according to its production mode is different, divided into cast aluminum alloy and deformation aluminum alloy two categories. Deformed aluminum alloy is generally used in construction, which can be rolled into plates, foils and strips, and extruded into bars, tubes or profiles of various complex shapes. Deformed aluminum alloy is divided into anti-rust aluminum alloy, hard aluminum alloy, super hard aluminum alloy and special aluminum alloy according to its performance and use. Industrial pure aluminum (L1 ~ L1), antirust aluminum alloy (LF2, LF21, etc.) and forged aluminum (LD2) are generally used in construction.
Characteristics and applications of aluminum and aluminum alloy is the most important characteristic, first of all, its bulk density is about 1/3 of steel, and the specific strength (strength limit and specific gravity ratio) can reach or exceed the structural steel. Secondly, aluminum and aluminum alloy are easy to be processed into various shapes and can adapt to various connection processes, thus providing favorable conditions for the construction structure to adopt the most economical and reasonable section form. Therefore, the use of aluminum alloy can not only greatly reduce the weight of the building, save materials, but also reduce the transport of components, installation work, speed up the construction schedule. The economic effect is more remarkable for earthquake areas and mountainous areas and remote areas with inconvenient traffic. Aluminum and aluminum alloy beautiful color, good corrosion resistance, high reflectivity to light and heat, good sound absorption performance, through chemical and electrochemical methods can be obtained a variety of different colors. Therefore, aluminum is widely used in industrial and civil building roof, walls, doors and Windows, skeleton, interior and exterior decorative panels, ceilings, suspended ceilings, handrails, indoor furniture, store containers and construction templates.
The construction industry is one of the three main markets of aluminum, about 20% of the total output of aluminum in the world is used for the construction industry, the construction industry of some industrial developed countries, the amount of aluminum has accounted for more than 30% of its total output. Building aluminum products are constantly updated, and the application of colorful aluminum plates, composite aluminum plates, composite door and window frames, aluminum template and other novel architectural products is also increasing year by year. China is already in industrial and civil construction.
