As the price of aluminum sheets continues to fall and people's awareness of the many advantages of aluminum sheets increases, more and more manufacturers are beginning to try to use aluminum sheets instead of other materials to obtain better appearance and performance. However, there are dozens of aluminum plate brands that are common in the market. The price difference is huge and the performance is different. Enterprises often take the trouble. Below, let us spread the type of aluminum plate for the enterprise.
Depending on the composition of the alloy, the aluminum sheets are currently divided into eight series in the market, namely:
Pure aluminum plate: Pure aluminum plate can be said to be the cheapest aluminum plate. Because it does not contain other alloying elements, the production process is the simplest and the application range is the widest.
Aluminum-copper alloy: The characteristics of aluminum plate are high hardness, among which the original content of copper is the highest, about 3-5%. The second-grade aluminum plate belongs to aviation aluminum and is not commonly used in conventional industries.
Aluminum-manganese alloy: The most widely used rust-proof aluminum plate, mainly used for low-load parts working in liquid or gaseous media, such as fuel tanks, gasoline or lubricating oil pipes, various liquid containers and other small deep-drawing products. Load parts, wires are used to make rivets.
Aluminum-silicon alloy: It belongs to the aluminum plate series with high silicon content. It usually has a silicon content between 4.5% and 6%. It belongs to construction materials, mechanical parts, forging materials and welding materials. Low melting point, good corrosion resistance, heat and wear resistance.
Aluminum-magnesium alloy: It belongs to the more common alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3% and 5%. It can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of the five-layer aluminum plate is lower than that of other series under the same area, and it is widely used in the conventional industry. The five-layer aluminum plate in China is one of the more mature aluminum plate series.
Aluminum-magnesium-silicon alloy: It mainly contains two elements of magnesium and silicon, so it concentrates on the advantages of the four-line and five-line. The six-layer aluminum plate is a cold-treated forged product suitable for applications requiring high corrosion resistance and oxidation resistance. Good workability, easy coating and good processability.
Aluminium-zinc-magnesium alloy: a typical high-end aluminum plate, also belonging to the aerospace series, is an aluminum-magnesium-zinc-copper alloy, which can be heat-treated and is a super-hard aluminum alloy. Seven-layer aluminum plate has good wear resistance, and currently relies on imports. China's production process needs to be improved.
Aluminum-lithium alloy: The eight-system is generally used for the production of aluminum foil. It is widely used in the food and pharmaceutical industries and has less application in the industrial field.
