A comprehensive explanation of 5-7 series high performance aluminium alloys for civil use

Aluminum alloys are light, have high specific strength and stiffness, are corrosion resistant, easy to shape, non-toxic, have good electrical and thermal conductivity, and can be subjected to various surface treatments. 6111, 6010, 6016, 6017, 6082, 2038 and CP609, etc.; 7021, 7029 and other alloys for car bumpers; 2011, 6262, 6043 and other alloys for mechanical cutting; 6005A, 7005 and Al a Zn a Mg medium-strength weldable alloys for rail cars; CP703, 7120, 6013 and other alloys for transportation; 6005A, 7005 and Al a Zn a Mg medium-strength weldable alloys for wires. Alloys such as CP703, 7120, 6013, etc. for transport; 1370, 1A60, 1R50 for conductors and 6101, 6201, A4/L, A4G/L, etc. of the AI-Mg-Si system; Al-si-Mg-Bi for heat exchangers (wrapped in alloys such as 3003 potting plates as brazing material); 4006 for stamping and enamelling ware and advanced PS Board base and high-performance easy to pull the body plate and fill the cover plate and other new alloys.

(1) High-grade civil construction aluminum alloy with the development of new materials aluminum alloy doors and windows, curtain walls and other civil construction materials in the fierce competition with plastics, composite materials, etc., to be invincible, the only way out is to constantly eliminate the middle and low-grade products, research and development of new high-grade products. In recent years, around 6063 alloy developed a series of new alloys for different purposes, such as 6463, 6463A, etc., and to 6061, 6351, 6082, 6013, 5005, 5052, 6005, 7005 and other medium-strength alloy development, the state also from a single T5 to T6 and other directions. At the same time the development of new varieties of heat insulation break bridge profiles and aluminum a plastic, aluminum a wood, aluminum a plastic a wood and other new materials, its application scope also from doors and windows, fences and other decorative parts to the roof, analysis frame, column, springboard, bridge, template and other load-bearing and structural parts of the direction of development, greatly strengthening the position of aluminum in the field of construction.
