Eight series numbers of aluminum and aluminum alloys
The first number of the code indicates the aluminum alloy series, the second number indicates the modification of the original aluminum alloy, and the last two numbers indicate the purity of the aluminum alloy in the same group.
1100: Good formability and high corrosion resistance are required for processing, but high-strength parts are not required. For example, storage containers, thin plate processing parts, deep-drawn concave vessels, heat exchangers, printing plates, nameplates, reflective appliances, etc.
2011: Free-cutting alloy, good machinability and high strength, but poor corrosion resistance, suitable for volume shafts, optical components, screw heads, screws and machined products that require good cutting performance.
3003: It has the properties of 1xxx series alloys and has higher strength than 1xxxx series alloys, such as kitchen utensils, food and chemical product processing and storage devices, tanks and tanks for transporting liquid products, and various pressure vessels and pipes for thin plate processing.
4A01: High silicon content, heat-resistant, wear-resistant, belonging to construction materials, mechanical parts, forging materials, and welding materials.
5052: The most representative alloy with medium strength (5083 is the highest), with good corrosion resistance, weldability and formability, especially high fatigue strength and good seawater resistance. It is used to manufacture aircraft fuel tanks, oil pipes, and transportation vehicles. Ship's sheet metal parts, instruments, street lamp brackets and rivets, hardware products, etc.
6061: Heat-treated corrosion-resistant alloy. T6 treatment can have a very high endurance value, but the welding interface strength is low, so it is suitable for screws, ships, vehicles, and land structures.
6N01: Medium-strength alloy for extrusion, which can be used as large-scale thin-meat profiles with complex shapes, with good corrosion resistance and welding properties. It is suitable for vehicles, land structures and ships.
6063: A representative extrusion alloy, with lower strength than 6061, good extrudability, can be used as profiles with complex cross-section shapes, good corrosion resistance and surface treatment, suitable for building highway guardrails, vehicles, furniture, and home appliances Products, decorations.
7072: Low electrode potential, mainly used for anti-corrosion covering skins, but also suitable for heat sinks of heat exchangers, aluminum foils for air conditioners and ultra-thin strips.
7075: One of the alloys with the highest strength among aluminum alloys, but the corrosion resistance is not good. The covering skin with 7072 can improve its corrosion resistance, but the cost is increased. Suitable for aircraft, ski poles, thick plates and forged products.
