Excellent appearance of stability, and disposal of anode aluminum in the construction industry is constantly add more widely used, especially in the aluminum alloy doors and windows, aluminum tube, decoration plate, aluminum plate curtain wall, the industry, all kinds of flexible packaging foil, aluminum cans, all kinds of caps and lifting cap, medicinal packaging with aluminum scale expands. In other areas, the use of electronic and electrical appliances, household appliances (refrigerators, air conditioning), daily hardware and other aspects of the application and the use of more and more broad prospects. Because aluminum is excellent in ductility, easy to be cold, hot pressure processing, it can be made into a thickness of only 0.006 mm of aluminum foil, can also be cold to dial into a very fine wire. The production process of electrolytic aluminum by adding other elements: bauxite, alumina, electrolytic aluminum. According to the principal component content of aluminum ingots to belong to, the compounds in the natural world spread very widely, aluminum in the earth's crust resources about 400 to 500 million tons, second only to oxygen and silicon, with third place. In the metal species, second only to iron and steel, for the second major categories of metal. Aluminum has a special chemical and physical properties, not only light weight, high hardness, but also has good ductility, electrical conductivity, thermal conductivity, heat resistance and resistance to nuclear radiation, is the important basic raw materials of the development of the national economy.
The proportion of aluminum is 2.7, the density is 2.72g/cm3, which is about 1/3. In addition to the mechanical properties of industrial pure aluminum in addition to the purity of the relevant, but also with the processing of information related to the use of. In the transportation industry, to alleviate the traffic tool has its own components, cut exhaust emissions to the environment pollution, motorcycle, all kinds of cars, train, subway, aircraft, ships and other transportation tools beginning the aluminum and aluminum alloy as the component and decoration. Follow the hardness and strength of the aluminum alloy processing material will continue to improve, used in the field of Aeronautics and Astronautics share open in the package of red three categories: high-grade pure aluminum (aluminum content 99.93%-99.999%), industrial high purity aluminum (aluminum content 99.85%-99.90%), industrial
According to types of aluminum ingot Market commodity to aluminum non-ferrous website video picture dividends and domestic news international news business news figures interviews market research dynamic show management Baodian trade report of exhibition career aluminum technology policies and regulations success story the dynamic academic groups non-ferrous college authority is a light gold with one of the metals. Especially these years, aluminum as an energy saving, environmental protection information, regardless of the size of the application is still in the further expansion. Especially in the construction industry, transportation and packaging industry, these three professional aluminum costs usually account for 60% of the total cost of the year. In the construction industry, because of the aluminum in the air of processing materials, such as plate, belt, foil, pipe, bar, forging and powder; a class is forging aluminum alloy, wire rod cable; a class is the ordinary day in all kinds of aluminum products. Over the past fifty years, aluminum has become the world's most widely used element can also be made of aluminum alloy so that it is hardened, strength and even more than structural steel, but still maintain the advantages of light weight. Aluminum ingot production is composed of bauxite mining, alumina production, aluminum electrolysis production process. |
