The commonly used aluminum base plates for aluminum substrates mainly include 1000 series, 5000 series and 6000 series.

The classification characteristics are as follows:

1000 series

Representing 1050, 1060, 1070, the 1000 series aluminum plate is also called pure aluminum plate. Among all the series, the 1000 series contains the most aluminum, and the purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industries. The 1050 and 1060 series are mostly circulated on the market at present. The 1000 series aluminum plate is based on the last two digits to determine the minimum aluminum content of this series. For example, the last two digits of the 1050 series are 50. According to the international brand naming principle, its aluminum content must reach 99.5% or more to be a qualified product. In my country's aluminum alloy technical standard (GB/T3880-2006), it also clearly stipulates that the aluminum content of 1050 reaches 99.5%. For the same reason, the aluminum content of the 1060 series aluminum plate must reach 99.6% or more.

5000 series

Represents the 5052, 5005, 5083, and 5A05 series. The 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%, which is also called aluminum-magnesium alloy. The main features are low density, high tensile strength, and high elongation. In the same area, the weight of aluminum-magnesium alloy is lower than other series, so it is often used in aviation, such as aircraft fuel tanks. In addition, it is widely used in conventional industries. Its processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series, so it can be sampled and deep processed. In my country, the 5000 series aluminum sheet is one of the more mature aluminum sheet series.

6000 series

Representative 6061 mainly contains two elements of magnesium and silicon, so it concentrates the advantages of 4000 series and 5000 series 6061 is a cold-treated aluminum forging product, suitable for applications with high requirements for corrosion resistance and oxidation. Good workability, excellent interface characteristics, easy coating, and good processability. The general characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability, and strong corrosion resistance. Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, ship parts and hardware, electronic parts and connectors, etc.

Considering the texture, hardness, elongation, chemical properties and price of the material itself, the 5052 alloy aluminum plate in the 5000 series aluminum material is commonly used for aluminum substrates.
