Aluminium is second only to silver and copper, and is widely used in electrical equipment and high voltage cables.Aluminum is one of the best reflectors of heat and light (including ultraviolet light), so it is used as an insulating material and reflectors in the reflecting telescope.The mirror in the world's largest telescope is painted aluminum.Aluminum can make aerospace equipment to reduce the harmful effects of ultraviolet radiation on the human body. The inner layer of a spacesuit is made of eight-layer synthetic fabric coated with metal aluminum.Aluminum also has good sound absorption performance, some broadcasting rooms, large building ceilings use aluminum to absorb sound.
Aluminum strength and mechanical properties in low temperature environment is still very good, so the aluminum will not only be frozen food transportation, storage devices and cold area of building materials, but also can be used for rocket storage tank of liquid hydrogen and liquid oxygen and other parts.Aluminum is a superconductor at temperatures below 2.
Aluminum has a good performance in architecture, and aluminum has good corrosion resistance.The parliament building in Moscow's kremlin is built of aluminum and glass.Aluminium alloys are now used in Bridges, buildings, hangars and underwater buildings.
Aluminum is used in large quantities by means of transportation.Aluminum also has a wide range of USES in the defense industry.A ship made of aluminum is not only fast, it is not eroded by the sea, it is not magnetic, it can prevent the magnetic mines from being attacked.
