The reason why aluminum circles are widely used
We all know that aluminum is very light in mass and it is much more resistant to corrosion than other metals, which are two of the most prominent characteristics of aluminum circles. Because of its small density and light weight, it is widely used in aviation, automobile, ship and other transportation manufacturing industries. In addition, spacecraft, satellites and other high-technology industries also use a large number of aluminum circles, aluminum metal and aluminum alloy.
Second, it has very good electrical conductivity. Its conductivity is weaker than that of copper, but because of its large reserves and small density, it is only one third of that of copper, so it takes only half the mass of copper to deliver the same amount of electricity. In addition, aluminum oxide film has not only the ability of corrosion resistance but also a certain degree of insulation, so aluminum circle metal in the electrical manufacturing industry, wire and cable and radio industry have a very common use.
Aluminum circles and aluminum alloys are often used in industry as forgings, which can cast various shapes and types of forgings, and can be connected by a variety of methods, including fusion welding, resistance welding and other electric welding methods can also be used for bonding and riveting and bolting mechanical methods. Thermite is also commonly used to smelt refractory metals and weld steel rails. It can also be used as deoxidizer in steelmaking process.
These are some of the characteristics of aluminum, and these characteristics are the reason why aluminum circle can be widely used.
Sigma aluminum could supply aluminum circle, others like aluminum sheet, aluminum foil, aluminum plate etc. Welcome you inquiry!
