Aluminum is a light, paramagnetic silver metal with high thermal and electrical conductivity and excellent corrosion resistance.
Aluminum is easy to machine, cast and mold, is the most common metal and is used in many areas of industry.
Aerospace and transport industry
Due to its lightness, high resistance toCorrosion and excellent ductility, this metal is used as the main structural material in the aviation and aerospace industries. The most heavily loaded parts of aircraft are made of duralumin: reinforcing set, sheathing, etc. It was used in the designs of the space satellites "Luna", "Venus", "Mars", visited the Moon and returned to earth. In addition, it was used as the main material for hulls of high-speed hydrofoil vessels "Raketa" and "Meteor". As a structural material, aluminum has a significant drawback - a low strength, so now it is gradually beginning to displace the composite materials.
In land transport, aluminum also receivedWide application. In the automotive industry for the first time it was used as decorative details in 1914. Now from this metal more than 100 various automobile details are made, and their quantity grows every year. This is evidenced by data obtained as a result of statistical studies, according to which, in 1948 3.2 kg was used to make one car, now large world companies use in some models from 100 to 150 kg. The rail transport is not far behind the cars.
Construction, casting and electrical engineering
Increasingly, "winged" metal is used inConstruction. In the new modern buildings, many elements made of aluminum alloys can now be found. Light and durable ceilings and beams, railings, fences, columns, ventilation elements and glazing made of aluminum are used in the construction of many public buildings and sports facilities.
In foundry production, an alloy of aluminum andSilicon gives small shrinkage and segregation makes it possible to obtain details of a very complex configuration. Blocks and engine housings, various types of impellers, pistons, cylinder heads and many other elements are made of this alloy by casting.
In electrical engineering, aluminum is used in linesPower transmission, in power cables and as a sheath of conductive elements. It is made of conductive tires, cable lugs and sleeves, cable channels, radiators, distributors, power substations and power lines.
Foil, used for packaging variousIndustrial and food products, from chocolate sweets and aluminum cans, to cosmetics and medicines is made of pure aluminum. More than 1 million tons of aluminum are consumed annually for the production of foils of various thicknesses and purposes. In the recent past, there was also very popular dishes and cutlery from food aluminum, which even now can be found in some catering establishments.
In addition, aluminum is used in the chemical, oil and gas industries as pipelines, tanks and assembly elements.
