1100 is industrial pure aluminum, with an aluminum content (mass fraction) of 99.00%, and cannot be strengthened by heat treatment. It has high corrosion resistance, electrical conductivity and thermal conductivity, low density, good plasticity, and can produce various aluminum materials through pressure processing, but low strength. Other process properties are basically the same as 1050A. 1100 is usually used for applications that require good forming performance, high corrosion resistance, and do not require high strength, such as food and chemical handling and storage equipment, sheet metal products, hollow hardware processed by drawing or spinning, welding combination keys, reflectors, nameplates, etc.

‌Application fields

1100 aluminum alloy has a wide range of applications, mainly including construction, electronics, automobile manufacturing, packaging and aerospace. ‌‌

In the construction field, 1100 aluminum alloy is often used to make building exterior wall panels, roof panels and ceilings due to its excellent corrosion resistance and plasticity. Its surface is smooth and flat, which can provide a beautiful appearance and has good fire resistance. In addition, 1100 aluminum alloy is also used to manufacture building appearance materials, such as aluminum plates, aluminum strips and aluminum profiles, which are widely used in the decoration and protection of roofs, walls, ceilings and facades.

In the electronics field, 1100 aluminum alloy is often used to manufacture electronic radiators, electronic packaging materials and electronic circuit boards due to its good electrical and thermal conductivity. Its thermal conductivity enables electronic equipment to dissipate heat more effectively and improve the stability and life of the equipment.

In automobile manufacturing, 1100 aluminum alloy is widely used to manufacture automobile bodies and body parts due to its lightweight characteristics. Its low density and high strength can reduce the weight of the car, improve fuel efficiency, and provide good safety performance.

In the packaging field, 1100 aluminum alloy is often used for packaging of products such as food, medicine and cosmetics due to its corrosion resistance and sealing performance. Its surface can be coated to improve corrosion resistance and anti-oxidation performance to ensure the quality and safety of packaged items.

In the aerospace field, 1100 aluminum alloy is widely used to manufacture aircraft fuselages and structural parts due to its lightweight and high-strength characteristics. Its lightweight characteristics can reduce fuel consumption, improve flight efficiency, and provide good structural stability.

In addition, 1100 aluminum alloy is also used to manufacture chemical equipment, storage tanks and pipelines, etc., and can operate stably for a long time in harsh chemical environments. It has good processing performance and can be processed through a variety of processes such as rolling, extrusion, stretching, cutting, stamping and welding.
