The first digit of the brand indicates the aluminum alloy series, the second digit indicates the modified condition of the original aluminum alloy, and the first two digits indicate the purity of the aluminum alloy in the same group.
1100: For processing needs have good formability and high corrosion resistance, but do not require high strength parts. Such as storage containers, sheet processing workpiece, deep drawing concave vessels, heat exchangers, printing plates, nameplates, reflective appliances, etc.
2011: Fast cutting alloy, good machinability and high strength, but poor corrosion resistance, suitable for volume shaft, optical components, screw heads, screws and mechanical products requiring good machinability.
3003: It has the function of 1xxx series alloy and has higher strength than 1xxxx series alloy, such as kitchenware, food and chemical products disposal and storage installation, liquid product transport trough, tank, as well as a variety of pressure vessels and pipelines for sheet metal processing.
4A01: High silicon content, heat resistance, wear resistance, construction materials, mechanical parts, forging materials, welding materials.
5052: The most representative alloy of medium horizontal strength (5083 is the highest), good corrosion resistance, solubility and formability, especially high fatigue strength, good seawater resistance, used in the manufacture of aircraft fuel tanks, oil pipes, as well as traffic vehicles, ships of sheet metal parts, instruments, street lamp brackets and rivets, hardware products.
