What is Aluminium
2024-09-11
Aluminium is a silver-white metal, is a light metal, its compounds in nature is widely distributed, the crust of the aluminium resources of about 40 to 50 billion tons, second only to oxygen and silicon, with the third. In the metal varieties, second only to steel, for the second largest category of metals.
Aluminium has special chemical and physical properties, not only light weight, firm texture, and has good ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance, aluminium ductility for custom aluminium profiles provide many possibilities.
The excellent characteristics of aluminium and its alloys are good appearance, light weight, machinability, good physical and mechanical properties, corrosion resistance, due to the lightness of aluminium, so it is commonly used in the manufacture of automobiles, trains, subways, ships, planes, rockets, spaceships, and other land, sea, and air transport to reduce deadweight to increase the load capacity of aluminium is also widely used in the military industry . It can also be used to make the more common LED aluminium profiles and Electronic cooling Aluminum Profile, and of course there are other lamps such as plant lights that often require aluminium heat sinks.
Aluminium has a specific gravity of 2.7 and a density of 2.72g/cm3, which is about 1/3 that of common metals. the mechanical properties of pure industrial aluminium are related to the processing state of the material in addition to its purity. Because aluminium is very good plasticity, ductility, easy to a variety of cold, hot pressure processing, aluminium processing of a common processing method is aluminium profiles extrusion.By adding other elements it is also possible to alloy aluminium so that it hardens and can even exceed the strength of structural steel, but still retains the advantage of being lightweight.
