What is aluminum sheet?
Aluminum sheet refers to a rectangular frame sheet made by rolling aluminum ingots. It can be pure aluminum sheet or aluminum alloy sheet. According to different application requirements, aluminum sheet can also be divided into different types such as thin aluminum sheet, medium thick aluminum sheet and pattern aluminum sheet. . Aluminum sheets have the characteristics of good light weight, corrosion resistance and thermal conductivity, so they are widely used in construction, automobile, aviation and other fields. The cross-section of the aluminum sheet is rectangular and the thickness is uniform, and when the thickness is greater than 0.2mm, it is usually delivered in a flat shape. Additionally, aluminum panels are often trimmed by shearing or sawing before delivery.
Classification of aluminum sheets:
1. According to the alloy composition, it is divided into: high-purity aluminum sheet (aluminum content is more than 99.9%), aluminum sheet (aluminum content is more than 99%), aluminum sheet alloy, aluminum sheet.
2. According to thickness, it is divided into: thin sheet (thickness between 0.2mm-6.0mm), medium-thick sheet (between 6.0mm-200mm).
Aluminum sheet forming methods: casting method, plastic molding method and deep processing method.
Aluminum sheets can be divided into two categories according to the characteristics of alloy heat treatment: non-heat-treatable strengthened aluminum alloys and heat-treatable strengthened aluminum alloys.
2-1. Aluminum alloys that cannot be strengthened by heat treatment: pure aluminum, aluminum-manganese alloy (Series 3), aluminum-magnesium alloy (Series 5), aluminum-silicon alloy (Series 4), etc.
2-2. Heat-treatable strengthened aluminum alloys: aluminum-magnesium-silicon alloy (6 series), aluminum-copper alloy (2 series), aluminum-zinc-magnesium alloy (7 series), etc.
3. According to the processing technology: cold rolling and hot rolling.
Functions of aluminum sheets: processability, plasticity, forgetability, and recoverability.
Aluminum sheet uses:
1. Construction field. Aluminum panels are used to make building curtain walls, ceilings, interior and exterior wall decorations, etc. They have good fire protection and anti-corrosion properties and are suitable for exterior and interior decoration of high-rise buildings, commercial buildings, airport terminals, squares, stadiums and other buildings.
2. Transportation field. Aluminum sheets are used to make car bodies, roofs, windshield frames and other components. Because of their light weight and high strength, they help improve the fuel efficiency and safety of cars.
3. Electronic field. Aluminum sheets are used to make casings, heat sinks, circuit boards, etc. of electronic products. Due to their conductivity and corrosion resistance, aluminum circuit boards are widely used in electronic products.
4. Packaging field. Aluminum sheets are used to make food packaging, cosmetic packaging, etc., and have good moisture-proof, anti-oxidation, and fresh-keeping properties.
5. Aerospace field. Aluminum sheets are used to manufacture exterior panels, fuel tanks, boosters, etc. for aircraft, satellites, and other equipment. Because of their high strength, light weight, and corrosion resistance, aluminum materials have been widely used in the aerospace field.
6. Other fields. Aluminum sheets can also be used for mechanical parts processing, mold manufacturing, chemical pipeline wrapping, etc.
Advantages of aluminum sheets:
1. Low density
2. Good electrical and thermal conductivity
3. Uniform coating and various colors
4. Easy to process
5. Strong corrosion resistance
