what is 3xxx series aluminum sheets?
3xxx series aluminum sheets can be called anti-rust aluminum sheets. It is mainly composed of manganese. The content is between 1.0-1.5. The production process of our 3 series aluminum sheet is more sophisticated.
3 series aluminum plate is a series with better anti-rust function, which is often used in humid environments such as air conditioners, refrigerators, and car bottoms. Its price is higher than the 1xxx series, which is a commonly used alloy series.
3000 series aluminum plate mainly represents 3003 3A21.
3003 is used for machining parts that require good formability, high corrosion resistance, good weldability or both, and require higher strength than 1xxx series alloys, such as kitchen utensils, food and chemical processing and Storage devices, tanks, tanks for conveying liquid products, various pressure vessels and pipes for sheet metal processing, etc.
3A21 aircraft fuel tanks, oil pipes, rivet lines, etc. Building materials, food and other industrial equipment, etc.

3 series aluminum plate Features:
aluminum alloy with manganese as the main alloy element, can not be strengthened by heat treatment, good corrosion resistance, good welding performance, and good plasticity. Disadvantages: The strength is low, but the strength can be strengthened by cold work hardening, and coarse grains are easily produced during annealing.
Applications: Air conditioners, refrigerators, car bottoms and other shells that require rust prevention, seamless oil pipes (3003 alloy) used on airplanes, and cans (3004 alloy).
Common grades of 3 series aluminum sheets and their applications
3 series aluminum alloy is also called an aluminum-manganese alloy. The manganese content is 1-1.5%. It is a widely used anti-rust aluminum alloy series. The strength of the 3 series aluminum alloy is higher than that of pure aluminum alloy, but it cannot be strengthened by heat treatment. But it has good plasticity after cold working (lower cold rolling) and annealing. Due to its good corrosion resistance and welding performance, it can be used in many industries such as the building decoration industry, electronic manufacturing industry, automobile manufacturing, and so on.
The main grades of 3 series aluminum alloys are 3003 aluminum plate, 3004 aluminum plate, 3104 aluminum plate, 3005 aluminum plate, and 3105 aluminum plate. Among them, 3003 aluminum alloy is the most widely used. 303 aluminum plate is easy to process and has good rust resistance. It can be used for rolling paint on the surface of raw aluminum to make various decorative curtain walls and aluminum ceiling gussets for indoor use. The roof color aluminum tile made by the brick press is light and durable, and its service life is longer than that of steel.
303 is cheaper than 5052 and welds well. Some manufacturers of truck fuel tank materials also use a 3003H24 aluminum plate to replace the pressure-bearing partition in the 5052 fuel tank, which reduces costs without affecting the use. 3004 alloy has higher strength and better formability than 3003 alloys. It can be used as the tank body of all aluminum cans, and can also be used as a device for chemical production and liquid storage. Alloy 304 and Alloy 3004 are very similar in composition, have high strength, and are easy to machine. In the TV manufacturing industry, 3104-O state boards are often used to make TV LCD backplanes, punch convex hulls, add electronic components, and form dense oxides after oxidation. The film is not only resistant to corrosion and oxidation but also has good insulation, which reduces the total weight of the finished product and ensures good heat dissipation performance. Alloy 305 is mostly used for high-end color-coated aluminum coils. It can be used in the building materials industry, roof partitions, prefab houses, etc. It can also be used to make air conditioners, refrigerators, and other radiators, internal parts, etc. Alloy 305 is mainly used to manufacture stamping parts such as bottle caps and bottle caps.
