ایلومینیم is a silvery-white metal that is lightweight and has good ductility, electrical conductivity, thermal conductivity, گرمی کے خلاف مزاحمت, and radiation resistance. A dense oxide film will form on the surface of aluminum in the air, so that aluminum has good corrosion resistance. The aluminum products that we usually see have been oxidized.
Because of its rich content and good performance, aluminum is often made into rods, flakes, foils, powders, ribbons and filaments, and is widely used in important industrial fields such as aviation, تعمیراتی, automobiles, and electric power.
Aluminum has the highest recyclability and highest regeneration efficiency of any structural metal used in industry. Due to the high corrosion resistance of aluminum, except for some aluminum chemical containers and devices, aluminum products are basically not corroded during their use, and almost all of them can be recycled. And the actual production energy consumption of recycled aluminum does not exceed 5% of the energy consumption of electrolytic aluminum. لہذا, recycling and recycling waste aluminum is an energy-saving project with huge benefits. According to data released by the U.S. Geological Survey in 2013, the amount of recycled aluminum in the United States in 2012 was 3.4 million tons, of which 53% came from waste scraps generated during the production process, اور 47% came from aluminum-containing waste products; recycled aluminum products accounted for the total aluminum consumption market. 35% of the amount.
Industrial pure aluminum is generally defined as aluminum with a purity of 99.0% کرنے 99.9%, and in China it is defined as aluminum with a purity of 98.8% کرنے 99.7%. China’s plastic deformation processing industry pure aluminum grades are 1080, 1080A, 1070, 1070A (L1), 1370, 1060 (L2), 1050, 1050A (L3), 1A50 (LB2), 1350, 1145, 1035 (L4), 1A30 ( L4-1), 1100(L5-1), 1200(L-5), 1235, وغیرہ.
صنعتی خالص ایلومینیم میں ایلومینیم کی عمومی خصوصیات ہیں۔, کم کثافت, اچھی برقی اور تھرمل چالکتا, اچھی سنکنرن مزاحمت, اچھی پلاسٹک پروسیسنگ کی کارکردگی, پلیٹوں میں عملدرآمد کیا جا سکتا ہے, سٹرپس, ورق اور extruded مصنوعات, وغیرہ, and can be used for gas welding, argon arc welding, spot welding. Industrial pure aluminum cannot be strengthened by heat treatment, but its strength can be improved by cold deformation. The only form of heat treatment is annealing. The recrystallization starting temperature is related to the impurity content and deformation degree, generally around 200°C
Aluminum can be cast by any of the casting methods. Aluminum has good plasticity and can be rolled into thin plates and foils; drawn into pipes and filaments; extruded into various civil profiles; it can be turned, milled, bored, planed, وغیرہ. at the maximum speed that most machine tools can achieve.
The surface of aluminum and its alloys is easy to form a dense and firm AL2O3 protective film. This protective film will only be destroyed under the intense action of halogen ions or alkali ions. لہذا, aluminum has good resistance to atmospheric (including industrial atmosphere and marine atmosphere) corrosion and water corrosion. It can resist the corrosion of most acids and organic substances, and the use of corrosion inhibitor can resist the corrosion of weak alkali; the use of protective measures can improve the corrosion resistance of aluminum alloy.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold. At room temperature, the equivalent volume conductivity of electrical aluminum can reach 62% IACS, and if calculated according to the conductivity per unit mass, its conductivity is twice that of copper.
The reflectivity of the polished surface of aluminum to white light is more than 80%, and the higher the purity, the higher the reflectivity. عین اسی وقت پر, aluminum has good reflective properties for infrared rays, ultraviolet rays, electromagnetic waves, heat radiation, وغیرہ.
Industrial pure ایلومینیم has a wide range of uses, and can be used as electrical aluminum, such as bus bars, wires, cables, and electronic parts; as heat exchangers, coolers, and chemical equipment; packaging supplies for food and medicine such as tobacco, tea, and sugar, and beer barrels, وغیرہ. Deep drawing products; used in buildings as roof panels, چھتوں, partition walls, sound-absorbing and heat-insulating materials, as well as household appliances, کھانا پکانے کے برتن, وغیرہ.
