What is 3A21 aluminum plate

3A21 aluminum plate is an Al-Mn series aluminum alloy, which belongs to the weldable LF21 aluminum alloy and is known for its excellent anti-rust properties. The material is not very strong, only slightly higher than industrial pure aluminum, and cannot be strengthened by heat treatment, so cold working is usually used to improve mechanical properties. 3A21 aluminum plate has high plasticity in the annealed state and is suitable for applications requiring high plasticity and good weldability, such as aerospace, equipment manufacturing, automobile industry, and transportation.

What is the welding performance of 3A21 aluminum plate?

3A21 aluminum plate has good welding performance and can be connected by a variety of welding methods, including argon arc welding (TIG welding), MIG welding, etc. Its welding characteristics are mainly reflected in the following aspects:

  • Good weldability: The chemical composition and organizational structure of 3A21 aluminum alloy make it very weldable and suitable for multiple welding processes.
  • Strength after welding: After welding, the strength of aluminum alloy changes little, which is suitable for application scenarios requiring mechanical properties.
  • Welding heat affected zone: During the welding process, the performance of the welding heat affected zone is well maintained, reducing the problems caused by heat effects.
  • Pre-welding treatment: In order to obtain better welding quality, it is recommended to clean the surface of the aluminum plate before welding to remove oxides and grease.

In general, 3A21 aluminum plate is an aluminum alloy suitable for engineering and manufacturing industries, with excellent welding performance, which can meet the needs of various industrial applications.

How to judge the quality of 3A21 aluminum plate?

There are several ways to judge the quality of 3A21 aluminum plate:

Appearance inspection:

Check whether the surface of the aluminum plate is flat and smooth, and whether there are obvious scratches, dents, bubbles and other defects.

Dimension measurement:

Use tools such as calipers and electronic scales to measure the thickness, length and width of the aluminum plate to ensure that it meets the standard specifications.

Chemical composition detection:

Detect the chemical composition of aluminum through spectral analysis or chemical sampling to ensure that it meets the composition requirements of 3A21 alloy.

Mechanical property testing:

Conduct tensile tests, hardness tests, etc. to verify whether its mechanical properties such as tensile strength, yield strength and elongation meet the specifications.

Welding performance test:

If the aluminum plate is used for welding applications, a welding test can be performed to check the strength and appearance of the weld to ensure that its welding performance is excellent.

Supplier qualifications:

Choose a reputable supplier and check its quality management system certification (such as ISO 9001) and other relevant certifications.

The above methods can be used to more comprehensively evaluate the quality of 3A21 aluminum plate.

Huawei aluminum alloy plate packaging and delivery

  • 1. Paper or film the aluminum plate to ensure that the surface of the aluminum plate is intact and without scratches;
  • 2. Plastic or kraft paper wrapping is used to prevent moisture and rain, ensuring that the aluminum plate is clean and free of dirt during transportation (each package has a moisture-proof desiccant to ensure the quality of our products in the rainy East and South China);
  • 3. Add wooden pallets and reinforce them with steel belts to avoid collisions during transportation and ensure that the geometric shape of the aluminum plate remains unchanged;
  • 4. Export products are all packaged in wooden boxes and brackets with fumigation marks;
  • 5. Package according to other packaging requirements of customers.
  • 6. Container transport:
    • 20ft GP:5898mm (Length)x2352mm (Width)x2393mm (Height), loading 18~25 tons.
