5052 aluminum plate is one of the representative products of 5 series products. 5052 aluminum plate is widely used in electronic product parts, precision machining, and various aspects of ships. Here are some common problems in the market about 5052 aluminum plates?
1. the surface of the aluminum plate has flaws
The surface problem of the
5052 aluminum plate, except for the case related to the blank, is mostly due to the fact that each machine is derived from the production process.
2. Defects such as color difference, black wire and sand hole after oxidation
There are many reasons for the black wire, such as the rolling mill oil that is not properly managed by the auxiliary machine, and the indentation caused by excessive pressure or excessive tension on the surface of the board. If it is rolled to thin material, these dark marks will change. It is getting thinner and thinner, forming dark lines or black lines, and sometimes it is not clear whether it is oil or marks, or even there is no color difference on the surface, but it is very obvious after oxidation. Seeing the inconsistent appearance is definitely a rejection. The appearance of black silk after oxidation is the most fatal. Once this happens, there is almost no room for survival, and the losses and consequences are irreparable. Secondly, the color difference, generally the appearance of the product, the color difference can not appear, any customer is reluctant to accept the similar "two skin face" said products, to eliminate these problems, or rely on the source of the machine to control.
The reason for the occurrence of sand holes: sand holes are generally internal structural problems. Because the impurities or water vapor are not removed when casting billets, or other elements are not stirred evenly, it is required to control the source of the ingot. it is good.
3, performance requirements: tensile strength, hardness, elongation, bending requirements, etc.
As for the performance problem, the most is the bending deformation. This part cannot be generalized because of the different use of the customer's products. However, there is a standard in how much temperature, how long, and how thick it is in the annealing process.
5052 aluminum plate is widely used, and the product classification is also more, but as long as we pay attention to the control of each link, the common problems to the source control, the process is stable, the products made will definitely be favored by the market!
