According to the processing method of aluminum alloy, it can be divided into deformed aluminum alloy and cast aluminum alloy. The number of aluminum and aluminum alloy is mainly divided into eight series. International grades (using four Arabic numerals, commonly used representations): A series of aluminum has good moldability and surface treatment properties, and is excellent in corrosion resistance in an aluminum alloy. Its strength is lower, the higher the purity, the lower its strength. The 2000 series aluminum rods are aerospace aluminum materials and are used as structural materials and are currently not commonly used in conventional industries. The 3000 series aluminum rods are mainly composed of manganese. 3000 series aluminum alloys are mainly composed of 3003, 3105 and 3A21. The content is between 1.0 and 1.5, which is a series with better anti-rust function. It is often used as a tank for liquid products, tanks, construction parts, construction tools, various lamp parts, and various pressure vessels and pipes for sheet metal processing. The formability, the solubility, and the corrosion resistance are all good. Generally, the silicon content is between 4.5 and 6.0%, and the silicon content is relatively high. The 4000 series aluminum rods represent 4A01 and 4000 series aluminum sheets are among the higher silicon content series. Good soup flow, less solidification shrinkage, belonging to building materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance, heat and wear resistance. 5000 series aluminum rods belong to the more common alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. The 5000 series aluminum alloy represents the 5052, 5005, 5083, 5A05 series. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of the aluminum-magnesium alloy is lower than that of other series under the same area, and it is widely used in the conventional industry. The 6000 series aluminum alloy represents 6061 mainly contains magnesium and silicon. Therefore, the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product suitable for applications requiring high corrosion resistance and oxidation resistance. Good workability, easy coating and good processability. It mainly contains zinc, and the 7000 series aluminum alloy stands for 7075. Also belonging to the aviation series, it is an aluminum-magnesium-zinc-copper alloy, which is a heat treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. At present, it basically relies on imports, and China's production process needs to be improved (new materials online). Cultured Stone Texture PU Sandwich Panel

<a series>
In all series, the 1000 series is the most aluminum-containing series with a purity of over 99.00%. The 1000 series aluminum plates are based on the last two Arabic numerals to determine the minimum aluminum content of the series. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand nomenclature, the aluminum content must reach 99.5% to be qualified products.
A series of aluminum materials are relatively soft, mainly used for decorative parts or interior parts.
<Second Series>
The characteristics are high hardness, but the corrosion resistance is not good, among which the original content of copper is the highest, 2000 series aluminum alloy represents 2024, 2A16, 2A02. The copper content of 2000 series aluminum plate is about 3-5%.
