According to the processing method, Alloy Aluminum sheet can be divided into two categories: deformed aluminum alloys and cast aluminum alloys.

Deformed aluminum alloys are further divided into non-heat treatable reinforced aluminum alloys and heat treatable reinforced aluminum alloys.
Cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys and aluminum-rare earth alloys according to their chemical composition.
There are nine series of deformed aluminum alloys:
1.1000 series
The 1000 series is the series with the most aluminum of all the series. The purity can reach more than 99.0%. Its classics are 1050 aluminum plate and 1060 aluminum plate.
It is characterized by low price, good electrical conductivity and high corrosion resistance. It can be used in the manufacture of electrical appliances, chemical equipment, signs, etc.
2. 2000 Series
The 2000 series is known for its high hardness. The representative is 2024, 2A16, 2A02. The 2000 series belongs to aviation aluminum.
3. 3000 series
The 3000 series belongs to the aluminum-manganese alloy, which is a series with anti-rust function. Its representatives are 3003 aluminum plate and 3A21. It can be used to make water storage tanks, cookware and pipes, etc.
4.4000 series
The 4000 series is a series with higher silicon content. Typically the silicon content is between 4.5% and 6.0%. It has good heat resistance and abrasion resistance. It can be used as building material, machine parts and welding material.
5.5000 series
The 5000 series belongs to the commonly used 4x8 aluminum sheet series. The main element is magnesium, and the magnesium content is between 3-5%. The main features are low density, high tensile strength, high elongation and good fatigue strength, but cannot be heat treated. It is used to make fuel tanks, oil pipes, ship parts, etc.
6.6000 series
The 6000 series contains mainly magnesium and silicon. It is a cold-treated forged product with high corrosion and oxidation resistance. Its representative is 6061 aluminum plate.
It can be used in various industrial structural parts that require high strength, weldability and corrosion resistance, such as trucks, buildings and ships.
