Analysis of common problems of 5052 aluminum sheet

Last Updated: 2023-07-21

The most useful application of 5052 aluminum sheet is appearance parts or electronic accessories. The common problems of 5052 aluminum sheet are as follows:

1. There are defects on the surface of the aluminum sheet

The surface problems of 5052 aluminum sheet, except for the case related to the blank, most of the reasons are derived from the various machines in the prodsuction process.

2. After oxidation, there are defects such as color difference, black silk, sand hole, etc.

There are many reasons for black wires, such as the rolling mill oil dripped on the auxiliary machine due to poor management, and the indentation caused by excessive pressure or excessive tension on the sheet surface. If thin material is rolled again, these dark marks will become It becomes thinner and thinner, forming dark lines or black lines, and sometimes it is not clear whether it is oil or traces, and there is no color difference on the surface at all, but the performance is very obvious after oxidation. For customers , Seeing the appearance of inconsistency, it must be rejected. The appearance of black silk after oxidation is the most life-threatening thing. Once this happens, there is almost no room for survival, and the losses and consequences brought about are irreparable. Secondly, chromatic aberration. Generally, the chromatic aberration cannot appear in prodsucts that are made of exterior parts. Any customer is unwilling to accept prodsucts like the “two skin face”. To eliminate these problems, it is still necessary to rely on the source machine to control.

Causes of sand holes: Sand holes are generally internal structural problems, which are caused by factors such as impurities or water vapor that are not cleaned out during the ingot casting, or other elements are not evenly stirred. Therefore, it is required to control and detect the source link of the ingot Great.

3. Performance requirements: tensile strength, hardness, elongation, bending requirements, etc.

As for performance problems, bending deformation is the most common. This link cannot be generalized due to the different uses of customers’ prodsucts. However, in general, there are standards for annealing process, how much temperature, how long, and how thick it is to retreat.

5052 aluminum sheet is widely used and has many prodsuct categories, but as long as you pay attention to the management and control of each link, control the common problems at the source, and the process is stable, the prodsucts made will definitely be favored by the market!
