The Characteristics and Application of 3-series Aluminum Coils

The 3 series aluminum coil, also known as rust proof aluminum plate, is mainly composed of manganese as the alloying element. The representative varieties are 3003 and 3004 aluminum plates, which have higher strength than industrial pure aluminum plates, good formability, weldability, and corrosion resistance. Due to the inability to strengthen heat treatment, cold processing is often used in the process to improve mechanical properties. Among them, the strength of 3004 is better than that of 3003, and the main states are o, H12, H14, H16, H18, H19, H32, H34, H36, H38, etc. So, let’s learn about the characteristics and applications of the 3 series aluminum coil together!

Features:

The most commonly used 3-series aluminum coils are 3003 brands of magnesium aluminum alloy. The 3003 aluminum plate is easy to process, has good rust prevention, and can be coated with colored paint on the surface of the original aluminum. Its service life is better than that of steel. 3003 is cheaper and has better weldability compared to 5052. Some truck fuel tank material factories use 3003H24 aluminum plates instead of 5052 to make pressure free partitions inside the fuel tank, which reduces costs and does not affect usage. The strength of 3004 alloy is higher than that of 3003, with better formability, high strength, and easy processing. After forming oxidation, a dense oxide film can be formed, which is not only corrosion-resistant but also has good insulation properties, reducing the total weight of the finished product and ensuring good heat dissipation performance.

使い方：

3 series aluminum coils are suitable for industrial pure aluminum plate applications and other areas with higher hardness requirements. They are commonly used in various fields such as kitchenware, food and chemical storage and transportation, heat sinks, household appliances (such as air conditioners, refrigerators, washing machines, etc.), and are a common series of magnesium aluminum alloy plates. Among them, 3004 and 3104 aluminum strips are currently the mainstream materials for producing tank bodies.

The 3 series aluminum coil, also known as aluminum manganese alloy, has a manganese content of 1-1.5% and is a widely used anti rust magnesium aluminum alloy series. The strength of the 3 series magnesium aluminum alloy is higher than that of pure magnesium aluminum alloy, and it cannot be strengthened by heat treatment. However, after cold processing (rolling by cold rolling mill) and annealing process, it has good plasticity, excellent corrosion resistance and welding performance, and can be used in many industries. For example, the real estate decoration industry, electronic manufacturing industry, automobile manufacturing industry, etc.

The main varieties commonly used for 3-series aluminum coils include 3003 aluminum plate, 3004 aluminum plate, 3104 aluminum plate, 3005 aluminum plate, 3105 aluminum plate, etc. Among them, 3003 brands of magnesium aluminum alloy are used in large quantities. The 3003 aluminum plate is easy to process, has good rust prevention, and the surface of the original aluminum is coated with colored paint. It can be used to make various decorative curtain wall panels and aluminum ceiling panels for indoor use.
