Application of aluminum in industry
At present, aluminum and its alloys are used in many fields of industry and technology. First of all, aluminum and its alloys use the aviation and automotive industries. Aluminum is widely used in other branches of industry: in mechanical engineering, electrical engineering and instrument making, industrial and civil construction, chemical industry, and production of consumer goods.
In the aircraft industry, aluminum has become the main metal due to the fact that its use has solved the problem of reducing the mass of vehicles and dramatically increase the efficiency of their use. Aluminum and its alloys produce aircraft, engines, blocks, cylinder heads, crankcases, gear boxes, pumps and other parts.
In the electrical industry, aluminum and its alloys are used to manufacture cables, bus bars, capacitors, AC rectifiers. In the instrument making industry it is used in the production of film and photo equipment, radiotelephone equipment, various instrumentation.
Aluminum was widely used in the manufacture of equipment for the production and storage of strong nitric acid, hydrogen peroxide, organic substances and food products due to its high corrosion resistance and non-toxicity.
Aluminum foil has become a very common packaging material, because it is much stronger and cheaper than tin. Also, aluminum has become widely used for making containers for preserving and snoring agricultural products. But storage is not limited to small jars, aluminum is used for the construction of granaries and other fast-erecting structures in demand in agriculture.
Also, aluminum is widely used in the military industry in the construction of aircraft, tanks, artillery systems, rockets, incendiary substances, and for many other purposes in military equipment.
Aluminum of high purity is widely used in such new fields of technology as nuclear power, semiconductor electronics, radiolocation.
Aluminum is widely used as an anti-corrosion coating, it perfectly protects metal surfaces from the action of various chemicals and atmospheric corrosion.
Widely used is another useful property of aluminum - its high reflectivity. Therefore, various reflecting surfaces of heating and illuminating reflectors and mirrors are made of it.
Aluminum is used in the metallurgical industry as a reducing agent in the production of a number of metals, such as chromium, calcium, manganese. It is also used for deoxidizing steel and welding steel parts.
Do not do without aluminum and its alloys alloys in industrial and civil construction. It is used for the manufacture of building frames, trusses, window frames, stairs, etc. In Canada, for example, aluminum consumption for these purposes is about 30% of total consumption, in the USA it is more than 20%.
Proceeding from all the above-mentioned ways of using aluminum, we can say that aluminum has firmly taken the first place among other non-ferrous metals in terms of production scale and value in the holding
