Features and application of 3000 series aluminum-manganese alloy
- Nov 20, 2018 -

The 3000 series aluminum plate is a series of aluminum plates with a wide range of applications in China. The main alloying element of the 3 series aluminum plate is manganese, so it is also called aluminum manganese alloy. At present, the commonly used 3 series aluminum plate brands in China are: 3003, 3004, 3005, 3A21 and so on.

3 series aluminum plate features

The biggest feature of the 1 and 3 series aluminum plates is their good rust and corrosion resistance. Due to the addition of manganese, the 3 series aluminum plate has higher corrosion resistance than the 1 series aluminum plate, and has good corrosion resistance to the atmosphere, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt aqueous solution, etc. The corrosion resistance in dilute acid is also very good, so it can be applied to many special environments.

2. The hardness of the 3 series aluminum plate is about 10%-20% higher than that of the pure aluminum plate. It can be cold worked to improve the strength, and has good formability, weldability and corrosion resistance under normal temperature conditions, and the welding performance is excellent.

Disadvantages of 3000 series aluminum plates

In the cold deformation state, the 3 series aluminum plate has a tendency to peel off and corrode, and the larger the deformation, the more severe the peeling. Since the color is not uniform after anodization, the anodizing treatment is generally not performed.

3 series aluminum plate use

3003 aluminum plate

3003 aluminum plate is the most widely used in 3 series aluminum plate. It is widely used in kitchen utensils, food and chemical products processing and storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes processed with thin plates, general utensils and heat sinks. , makeup board, photocopying machine drum, marine materials.

3004 aluminum plate

The strength of 3004 aluminum plate is higher than 3003 aluminum plate, mainly used in chemical product production and storage devices, thin plate processing parts, building materials, building baffles, cable pipes, sewers, various lighting parts, beverage cans, wave boards, building materials, color aluminum plates, Electric light head.

3005 aluminum plate

The strength of the 3005 aluminum plate is higher than that of 3003 and 3004, and is generally used for building materials and color coated aluminum plates.
