The Reason for Aluminum Coil Becoming Brittle

The reasons for aluminum coils being brittle may include the following aspects:

1. Material issue: If the aluminum coil material contains a large amount of impurities or other defects, it may lead to brittle fracture of the aluminum coil.

2. Processing issues: Improper operation or handling during the processing of aluminum coils may lead to brittle fracture of the coils. For example, in processes such as cold working, hot working, welding, etc., if the temperature is uneven or the stress during the processing exceeds the material’s bearing range, it is easy to cause brittle fracture of the aluminum coil.

3. Storage environment issues for aluminum coils: If the aluminum coil is exposed to moisture, high humidity, or high temperatures during storage, it may cause surface oxidation or intergranular corrosion, leading to brittle fracture of the aluminum coil.

4. Surface treatment issues of aluminum coils: If the surface treatment is improper, such as uneven coating, poor quality, etc., it may reduce the corrosion resistance and oxidation resistance of the aluminum coil, leading to brittle fracture of the aluminum coil.

In short, the brittleness of aluminum coils may be caused by factors such as material, processing, storage environment, and surface treatment. Choosing high-quality aluminum coil suppliers is an important measure to reduce the occurrence of aluminum coil brittleness. Meanwhile, when processing and using aluminum coils, relevant standards and specifications should be followed to ensure their safe use.
