The Wide Applications of Aluminum Alloy Sheets
Aluminum alloy features low density, good mechanical properties, good processing properties, electrical conductivity, heat transfer and corrosion resistance,etc. Therefore, it is widely used in the marine industry, chemical industry, aerospace, metal packaging, transportation, etc. Let’s have a look together.
Aerospace
2xxx and7xxx aluminum alloy such as 2024 aluminium sheet are the main alloys used in aerospace industry. Its strength is similar to that of mild steel, but it is much lighter. And most of them have strong corrosion resistance and convenient processing. 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 aircrafts according to the content of its alloying elements. Super-duralumin is duralumin containing zinc. Its hardness and strength are higher than duralumin. Different varieties of super-duralumin is used to manufacture various structural parts and high-load parts.
Marine Industry
Aluminum and aluminum alloys are used more and more widely in the shipbuilding industry, ranging from small motorboats to cruise ships, from offshore hovercraft to submarine, from fishing boat to marine mining vessels. Marine grade aluminium is used to make shells, support structures, supporting facilities, pipelines, etc.
Aluminum alloy used in the marine industry can reduce the overall weight of the ship, increase the speed of the ship, and resist the corrosion of the ship by seawater. The aluminum alloys used in the marine industry are mainly aluminum-copper alloys, aluminum-magnesium alloys and aluminum-silicon alloys.
Aluminum-magnesium alloys are mainly used for hull shells, water pump pipes, pump shells and frame brackets, etc. The typical ones are 5052, 5083, 5456 and 5086 plate.
Chemical Industry
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 does not produce sparks, which can produce containers that contain easily volatile substances. Aluminum is non-toxic, which will not cause food deterioration and does not corrode goods. Therefore, aluminum alloys are widely used in the production of food and chemical equipment.
Metal Packaging Industry
Aluminum bottle cap material is widely used for beer, beverage and other food cans. Aluminum foil container is of light weight and good heat transfer, which are often used for fast food packaging. They have the functions of taste preservation and non-toxicity.
