Aluminum Tube Target  155OD*125ID*888L Vacuum Coating Target

Aluminum is a light silver metal. It's malleable. Commodities are usually made in column, rod, sheet, foil, powder, ribbon and filamentous form. In humid air, an oxide film can be formed to prevent metal corrosion. The aluminum powder, which has been treated with acid, burns violently in the air with heat and emits a blinding white flame. Aluminum and its alloy are widely used and one of the most economical materials. The world aluminum output from 1956 began to exceed copper output has been the first non-ferrous metal. The current production and consumption of aluminum (calculated by tons) is second only to steel, making it the second largest metal used by human beings. And aluminum is very rich in resources, according to preliminary calculations, aluminum mineral deposits account for more than 8% of the crustal material.
Aluminum's light weight and corrosion resistance are two outstanding characteristics of its performance.
1, aluminum density is very small, can be made into a variety of aluminum alloy, such as hard aluminum, super hard aluminum, rust aluminum, cast aluminum, etc.. These aluminum alloys are widely used in aircraft, automobiles, trains, ships and other manufacturing industries. In addition, space rocket, space shuttle, artificial satellite also use a large number of aluminum and its aluminum alloy. For example, a supersonic plane is made up of about 70 percent aluminum and its aluminum alloy. Aluminum is also used extensively in ship construction. A large passenger ship often uses several thousand tons of aluminum.
2. Aluminum is second only to silver, copper and gold in electrical conductivity. Although it has only two thirds the conductivity of copper, it has only one third the density of copper, so it has only half the mass of copper to transport the same amount of electricity. The oxide film on the surface of aluminum not only has the ability of corrosion resistance, but also has a certain insulation, so aluminum is widely used in electrical manufacturing industry, wire and cable industry and radio industry.
3, aluminum is a good conductor of heat, its thermal conductivity is 3 times greater than iron, industrial aluminum can make all kinds of heat exchangers, heat dissipation materials and cooking utensils.
4, aluminum has good ductility can be made into aluminum wire, aluminum strip, and can roll a variety of aluminum products.
5. The surface of aluminum has a dense oxide protective film, which is not easy to be corroded. It is often used to manufacture chemical reactors, medical devices, refrigeration devices, petroleum refining devices, oil and gas pipelines, etc.
