The Use and Application Prospects of Aluminum

The Use and Application Prospects of Aluminum
brief introduction
Due to its abundant reserves and excellent performance, aluminum is widely used in industry and daily life. Below, we will briefly introduce the application of aluminum based on its performance.
A. Low density
The density of aluminum in aluminum alloy power cables is 2.7g/cm ³ (one-third of the density of iron and copper), with good ductility and conductivity equivalent to two-thirds of copper wire, but with a quality of only one-third, it is cheaper and widely used in the manufacturing of high-voltage wires, cables, and wireless industries. Pure aluminum has a relatively low density, but the density and hardness of aluminum alloys have greatly improved. Currently, aluminum alloys have been widely used in manufacturing industries such as airplanes, automobiles, trains, and ships. In addition, space rockets, shuttles, and artificial satellites also use a large amount of aluminum and its alloys.
B. Thermal conductor
Aluminum is a good conductor of heat (with a thermal conductivity three times greater than iron), and can be used in industry to manufacture various heat exchangers, heat dissipation materials, and cookware.
C. Extensibility
Aluminum has good ductility (second only to gold and silver) and can be made into aluminum foil thinner than 0.01 mm at temperatures ranging from 100 ℃ to 150 ℃. These aluminum foils are widely used for packaging cigarettes, candies, etc. They can also be made into aluminum wires and strips, and can be rolled into various aluminum products.
D. Corrosion resistance
In the air, aluminum forms a dense oxide protective film on its surface, making it corrosion-resistant. Therefore, it is often used in the manufacturing of medical devices, chemical reactors, refrigeration devices, petroleum refining devices, petroleum and natural gas pipelines, etc.
E. Catalyst
Aluminizing agents are commonly used for melting refractory metals and welding steel rails. Aluminum is also used as a deoxidizer in the steelmaking process. Aluminum powder, graphite, titanium dioxide (or other high melting point metal oxides) are uniformly mixed in a certain ratio and coated on the metal. After high-temperature calcination, they are made into high-temperature resistant metal ceramics, which have important applications in rocket and missile technology.
F. Burning
Aluminum can emit a large amount of heat and dazzling light when burned in oxygen, and is commonly used in the production of explosive mixtures, such as ammonium aluminum explosives (composed of aluminum powder, ammonium nitrate, charcoal powder, smoke black, and other combustible organic compounds), combustion mixtures (such as bombs and shells made with aluminothermic agents that can be used to attack difficult to ignite targets or tanks, cannons, etc.), and lighting mixtures (such as those containing 28% aluminum powder, 68% barium nitrate, and 4% shellac).
G. Decorative
Aluminum powder has a silver white luster (usually the color of metals in powder form is mostly black), and is commonly used as a coating, commonly known as silver powder or silver paint, to protect iron products from corrosion and be beautiful.
H. Low temperature resistance
Low temperature resistance, aluminum actually increases its strength without brittleness at low temperatures, making it an ideal material for low-temperature devices such as refrigerated warehouses, freezers, Antarctic snow vehicles, and hydrogen oxide production equipment.
I. Reflectivity
Aluminum plates also have good light reflection performance, reflecting ultraviolet rays stronger than silver. The purer the aluminum, the better its reflection ability. Therefore, it is commonly used to manufacture high-quality mirrors, such as solar stove mirrors.
J. Additives
Some food additives also contain metal aluminum, such as alum, leavening agent, leavening agent, etc. They are also used in some deep-fried dough sticks, Mantou, Fried Dough Twists, vermicelli, and some puffed food (potato chips, etc.).
K. Sound absorption effect
Aluminum has sound absorption performance and good sound effects, so ceilings in broadcasting rooms and modern large buildings also use aluminum. Many doors and windows in households use aluminum alloy frames for this reason.
The current aluminum industry is facing overcapacity and insufficient utilization, and the prospects for the domestic aluminum industry are difficult to predict in the short term. However, due to its abundant reserves in the Earth's crust and its advantages over other metallic elements, aluminum will still have extremely broad application prospects in the future. Automobile manufacturers are currently exploring the use of aluminum alloys to replace steel in large areas, thereby making cars lighter in weight. With technological progress, aluminum alloy products will continue to grow rapidly not only in traditional application fields such as aerospace, transportation, electronics and power, and construction, but also in new fields.
