The use of matter is largely determined by the nature of matter.. Because of its many good properties, aluminum has a very wide range of uses.. Aluminium and aluminium alloys are one of the most widely used and economical materials for the current application.. The output of the world has been more than the first in the nonferrous metals since 1956.. The aluminum production and consumption (by tonnage) after the steel to become human application of the second metal; and aluminum resources are very rich, according to preliminary calculations, aluminum mineral storage capacity accounted for more than 8% of crustal materials.The weight of aluminum is light and corrosion-resistant, and is the two outstanding feature of its performance..The density of aluminum is very small, only 2.7 g / cm, although it is relatively soft, but can be made into a variety of aluminum alloy, such as duralumin and super hard aluminum, rust proof aluminum, cast aluminum, etc.. These aluminum alloys are widely used in aircraft, automobiles, trains, ships and other manufacturing industries.. In addition, the space rocket, the space shuttle, the man-made satellite also uses a lot of aluminum and its aluminum alloy. For example, a supersonic aircraft about 70% aluminum and its alloy constitutes. Shipbuilding is also widely used in aluminum, a large passenger ship used often as much as thousands of tons of aluminum.The conductivity of aluminum after silver, copper, and gold, although its conductivity copper is the only 2 / 3, but the density of copper is the only 1 / 3, so transporting amounts of electricity, the quality of aluminum copper only half. Aluminum oxide film not only has the ability to resist corrosion, but also has some insulation, so aluminum in the electrical manufacturing industry, wire and cable industry and radio industry has a wide range of uses.

Aluminum is a good conductor of heat. It is 3 times greater than iron, and can be used in various heat exchangers, heat dissipation materials and cooking utensils.. Aluminum has good ductility (which is second only to gold and silver), and can be made into 0.01 mm aluminum foil at 100 for 150.. These aluminum foil widely used in packaging cigarettes, candy, etc., can also be made of aluminum, aluminum, and can rolling a variety of aluminum products. The surface of the aluminum due to dense protective oxide film and less susceptible to corrosion, is often used to manufacture chemical reactor, medical equipment, refrigeration equipment, oil refining device, oil and natural gas pipeline. Aluminium has a silvery sheen (general metal powder color is black), used to make paint, commonly known as silver, silver paint, to protect iron products corrosion, and the shape is beautiful.Aluminum in oxygen combustion can release a lot of heat and glare, commonly used in the manufacture of explosive mixture, such as ammonium aluminum explosive (by ammonium nitrate, charcoal powder, aluminum powder, soot and other combustible organic matter mixed), combustion mixture (such as using thermite bombs and shells can be used to attack is difficult to ignite the goals or tanks, artillery, and so on) and lighting mixture (such as those containing barium nitrate 68% and 28% of aluminum powder, shellac, 4%). Thermite used to smelting of refractory metal and welded steel etc.. Aluminium is used as an agent for steelmaking.. Aluminum and graphite, titanium dioxide (or other high melting point metal oxides) are uniformly mixed in a certain ratio in and then, painted on the metal, calcined at high temperature made high temperature of the metal ceramic, it on the rocket and missile technology has important applications. The reflective performance of the plate is good, the ultraviolet is stronger than the silver, and the more pure the aluminum is, the better the reflection ability is. Therefore, it is often used to manufacture high quality reflective mirror, such as solar mirror, etc.. Aluminum has the sound absorption performance, sound effect is also good, so broadcasting room, a large modern building indoor ceiling are made of aluminum. Low temperature resistant, aluminum at low temperature and its intensity but increased and no brittle. Therefore, it is ideal for low temperature device materials, such as frozen library, the freezer, the Antarctic snow vehicles, the oxidation of hydrogen production device.
