What are the applications of aluminum alloy?

Aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, non-toxic, easy recovery, excellent conductivity, heat transfer and corrosion resistance. It is widely used in marine industry, chemical industry, aerospace, metal packaging, transportation and other fields.
Aerospace
Aluminum alloy is the main material used in the manufacture of aircraft. Compared with the mild steel used in the manufacture of automobiles, aluminum alloy is expensive, has a low density, and has a relative density of 2.8. Compared with the 7.8 of mild steel, it is about 1/3 lighter. Although the strength is similar, for aircraft, the material is light. The most important, and the corrosion resistance is strong, and the processing is convenient, so aluminum alloy is the most ideal material for manufacturing aircraft.
Hard aluminum according to its different alloy element content can be made of rivets, aircraft propellers and aircraft high-strength parts; super hard aluminum is hard aluminum containing zinc, its hardness and strength are higher than hard aluminum, different varieties of super hard aluminum used in the manufacture of various structural parts, high-load parts, is one of the important materials in the aviation industry.
Marine industry
Aluminum and aluminum alloys are more and more widely used in the shipbuilding industry, ranging from small motorboats to 10,000-ton oil tankers, from sea hovercraft to submarine, from civilian to military, from fishing vessels to marine mining vessels, all use aluminum alloys with excellent comprehensive performance to produce ship shells, bracket structures, supporting facilities, pipelines, etc.
Aluminum alloy used in the marine industry, can make the overall quality of the ship weight reduction, the use of ship speed, and can resist the corrosion of the sea to the ship.
Aluminum alloys used in the marine industry are mainly aluminum-copper alloys, aluminum-magnesium alloys and aluminum-silicon alloys. Aluminum-copper alloy is widely used in ships in China and Russia, but its poor resistance to seawater corrosion hinders its development in the shipbuilding industry. Aluminum magnesium alloy is mainly used for hull shell, water pump conduit, pump shell and frame bracket, etc. The brands are 5083, 5086, 5456, 5466, etc. The aluminum-silicon alloy has moderate structural strength, good fluidity, and strong filling ability. It is easy to produce parts with high density and complex structure, such as high-pressure valves, cylinder blocks, pumps, gearbox housings, turbine blades, etc.
