Application of aluminum alloy;
1, aerospace
Aluminum alloy is the main material for making airplanes. Compared with the low-carbon steel used in automobile manufacturing, aluminum alloy is expensive and has low density, with a relative density of 2.8, which is about one third lighter than the low-carbon steel of 7.8. Although the strength is almost the same, for aircraft, the light material is the most important, the corrosion resistance is strong and the processing is convenient, so aluminum alloy is the most ideal material for manufacturing aircraft.
2. Seawater industry
Aluminum and aluminum alloys are widely used in shipbuilding, from motorboats to 10,000-ton oil tankers, from offshore hovercraft to submarines, from civilian to military, from fishing boats to offshore mining ships. Aluminum alloys with excellent comprehensive properties are used to produce ship shells, supporting structures, supporting facilities and pipelines.
3. Application in chemical industry
Aluminum has good thermal conductivity. Aluminum and aluminum alloys are widely used in the production of heat exchange equipment in chemical equipment, storage tanks resistant to concentrated nitric acid corrosion, adsorption filters, fractionators, pipelines and many linings.
4. Application in metal packaging industry
Aluminum alloy can be used for metal packaging, and has the following excellent characteristics: good mechanical properties, light weight, high compressive strength, durability, and convenient storage and transportation of goods; Good barrier performance, can block the damage of sunlight, oxygen and humid environment to articles, and can prolong the shelf life of articles.
5. Application in other industries
Aluminum alloy has high specific strength, light weight, good fluidity, strong mold filling ability, good corrosion resistance and low melting point, and is widely used in tractors, locomotive parts, electronic products, medical devices, architectural decoration and other industries. Aluminum alloy has excellent ductility and is widely used in daily necessities industry and food industry.
