Commonly used grades of aluminum

The first digit of the grade indicates the aluminum alloy series, the second digit indicates the modification of the original aluminum alloy, and the last two digits 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.aluminum coil roll price - Decoulife

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, 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: A medium-strength extrusion alloy, which can be used for large-scale thin-meat profiles with complex shapes, with good corrosion resistance and welding properties. 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 leather materials, 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.

Examples of aluminum material selection

The product requirements are relatively hard, and the surface treatment is coarse wire drawing or coarse sand surface. Choose 5000 series aluminum alloy, commonly used: 5052

For products with high requirements for surface treatment, there should be no sand holes and profile traces. Choose 6000 series aluminum alloy, commonly used: 6063/6061

The product requires a low price, and it needs to be stretched and re-examined. The 2000 series pure aluminum is selected. Commonly used: 2011

The product has high strength and high hardness, and it needs to be used for load-bearing structure. Choose 7000 series aluminum alloy, commonly used: 7075
