ã€China Aluminum Industry Network】Aluminum alloy is lightweight, high specific strength, corrosion resistance, easy to form, non-toxic, good electrical and thermal conductivity, and can be used for various surface treatments. Therefore, aluminum alloy materials are used in transportation, new energy and civil use. Building, electronics and power engineering, packaging, printing, and home appliances have been widely used. Countries have successively developed a series of high-performance civil aluminum alloys, such as automotive body panels alloys 6009, 6111, 6010, 6016, 60l7, 6082. , 2038 and CP609, etc.; Alloys such as 7021, 7029 for automobile bumpers; Alloys such as 2011, 6262, 6043 for machine cutting; 6005A, 7005 and Al-Zn-Mg medium weldable alloys for rail cars; Alloys such as CP703, 7120 and 6013; Alloys 1370, 1A60 and 1R50 for conductors and Alloys 6101, 6201, A4/L and A4G/L for AI-Mg-Si alloys; Al-si-Mg for heat exchangers A Bi alloy (wrap it on a 3003 cover plate and other alloys as a brazing material); 4006 alloys for stamping and enamelware, as well as advanced PS plate bases and new high-performance easy-to-fuse body panels and cover plates.
(l) The research and development of high-grade civil building aluminum combined new materials In the fierce competition with plastics and composite materials, such as aluminum alloy doors and windows, curtain walls, etc., in order to be invincible, the way out is to continuously eliminate medium and low grades. Products, research and development of new high-end products. In recent years, a series of new alloys have been developed around 6063 alloys, such as 6463, 6463A, etc., and the development of medium strength alloys such as 6061, 6351, 6082, 60l3, 5005, 5052, 6005, 7005, etc. T5 develops in the direction of T6. At the same time, we developed new types of insulation and broken bridge profiles and new materials such as aluminum and plastic, aluminum and wood, and aluminum, plastic and wood. The scope of application also includes doors, windows, fences and other decorative parts to roofs, shelves, columns, and springboards. The development of bearing and structural components such as bridges and formwork has greatly strengthened the position of aluminum in the construction field.
(2) Development of high-performance ultra-thin plate aluminum alloy new materials Modern high-end decorative and coated plates, advanced mirror panels, skin panels and advanced PS plate bases, ultra-thin tank plates and advanced aluminum foil wool, etc., for aluminum alloys The requirements for composition, purity, structure and performance, and surface quality and precision are very high. Therefore, various countries are developing new alloys and states such as 801l, l050A, 1350A, 3103, 3105, 5052A, 5N01, 5657, 5182, 3204, 3404 and other alloys and H2n, H3n and other states, research new preparation methods and processes to meet market demand.
(3) R&D of high-performance electronic aluminum alloys The use of aluminum foil is very versatile. In order to produce new materials for aluminum foils of various properties, functions, and uses, various countries have developed new alloys for aluminum foils, especially high performance. Electronic and capacitor aluminum foil with new aluminum alloy, such as industrial pure 1074A, 1060, 1050A aluminum alloy and high purity aluminum 1A09, 1A93, 1A85 and other aluminum alloys.
(4) Development of large aluminum alloy special profiles for transportation The variety of large aluminum alloy special profiles for transportation is increasing, and the requirements for performance and quality are getting higher and higher. Therefore, it is necessary to develop new alloys with different performance requirements. Currently, new alloys that have been successfully developed include 6005, 6005A, 6N01, 7N01, and 7005.
