Analysis of Common Problems of 5052 Aluminum Plate

The biggest use of 5052 aluminum plate is appearance parts or electronic accessories. The common problems of 5052 aluminum plate are as follows:

1、 The surface of the aluminum plate is defective

Most of the surface problems of 5052 aluminum plate are derived from the production process of each machine train, except that the case is related to the blank.

2、 After oxidation, there are color difference, black wire, sand hole and other defects

There are many reasons for black wires, such as the rolling oil dripping on the auxiliary train due to poor management, and the indentation on the plate surface caused by excessive pressure or tension. If rolling to thin material, these dark marks will become thinner and thinner, forming dark lines or black lines. Sometimes it is impossible to distinguish whether it is oil or mark, or even there is no color difference on the surface, but it will be very obvious to customers after oxidation, If you see the appearance inconsistency, you must refuse it. Black silk after oxidation is the most life-threatening. Once this happens, there is little room for survival, and the losses and consequences can not be made up. Secondly, color difference. Generally, the color difference of products for appearance parts cannot appear. No customer is willing to accept products similar to the "two skin face". To eliminate these problems, we still need to control them by the source machine train. Causes of sand holes: sand holes are generally caused by internal structure problems. During ingot casting, impurities or water vapor are not eliminated completely, or other elements are not stirred evenly. Therefore, it is required to control and detect the source link of ingot casting.

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

As for the performance problem, the most important thing is bending deformation. This link cannot be generalized because of the different uses of customers' products, but generally in the annealing link, there are standards for how much temperature, how long and how thick to return.

5052 aluminum plate has a wide range of uses and product classifications, but as long as we pay attention to the control of all links, control the common problems at the source, and the process is stable, the products produced will certainly be favored by the market!
