What Are The Popular Uses of Aluminum Alloys
Aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, high recyclable value, excellent electrical conductivity, heat transfer and corrosion resistance. It is widely used in the marine industry, chemical industry, aerospace, metal packaging, transportation, etc.
1. Aerospace industry
Aluminum alloy is the main material used in manufacturing aircraft. Compared with mild steel used in automobile manufacturing, aluminum alloy is expensive and has a low density, with a relative density of 2.8. Compared with mild steel with a relative density of 7.8, it is about one-third lighter.
Although they have similar strength, for aircraft, lightness of material is the most important, and aluminum alloy has strong corrosion resistance and is easy to process. Therefore, aluminum alloy is the most ideal material for manufacturing aircraft.
Duralumin can be used to manufacture rivets, aircraft propellers and high-strength parts on aircraft depending on the content of its alloy elements; superduralumin is duralumin containing zinc, and its hardness and strength are higher than duralumin.
2. Marine industry
Aluminum and aluminum alloys are used more and more widely in the shipbuilding industry, like yachts, fishing boat, john boat, catamaran, tugboat,etc. They are used to produce ship shells, bracket structures, supporting facilities, pipelines, etc.
Aluminum alloys are used in the marine industry to reduce the overall weight of the ship, increase the speed of the ship, and resist seawater corrosion on the ship. The aluminum plate grades are usually Al-Mg alloys. Aluminum-magnesium alloys are mainly used in ship hull, water pump conduits, pump casings and machine base brackets, etc. The marine grade aluminum for sale grades include 5083, 5086, 5456, 5466, etc.
3. 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, fractionation towers, pipelines and many linings.
Aluminum is non-toxic, does not cause food deterioration, does not affect the appearance of goods, and does not corrode goods. Therefore, aluminum alloys are widely used in the production of related equipment in the food and chemical industry.
4. Metal packaging
Aluminum alloy can be used for metal packaging. It has the following excellent characteristics: good mechanical properties, light weight, high compressive strength, durability, easy to store and transport goods. Aluminum alloy used for packaging has a unique metallic luster, good touch, beautiful appearance, and improves product quality.
Aluminum foil containers are beautiful, lightweight and have good heat conductivity. Aluminum alloy metal hoses can be extruded and deformed, and the contents can be used by squeezing them. It is simple and convenient and is often used for packaging paste cosmetics.
5. Other industries
Aluminum alloy has high specific strength, light weight, good fluidity, strong mold filling ability, good corrosion resistance, and low melting point. It is widely used in tractors, motorcycle parts, electronic products, medical equipment, building decoration and other industries. Aluminum alloy has excellent ductility and is widely used in the daily necessities and food industries.
In the field of power transmission, wires made of aluminum alloy have low cost, light weight, good corrosion resistance, heat transfer, easy conduction and wear resistance, so they have attracted more and more attention. In the field of power transmission, aluminum alloys are used the most, and up to 90% of high-voltage conductor materials are aluminum alloys.
