Some metal materials are added to the alloy aluminum plate during processing. By adding these metal materials, the aluminum plate can have a certain strength and improve its performance. The strength, quality and hardness will be improved. Therefore, it is widely used in some fields of industrial production.
As it is used more and more, there are many kinds of aluminum plates on the market at the time of purchase, which dazzle consumers. Many kinds of aluminum plates also mean that the quality of aluminum plates may vary. Therefore, special attention should be paid to the selection. So what should we pay attention to in its selection? Now let's take a look.
1、 Oxidation degree
In the selection of aluminum alloy plate, you can lightly scratch the surface of the profile to see if you can wipe off its oxide film. If you can, it means that the post-treatment of the aluminum plate is not good, so it is not recommended to buy it.
The color of the same aluminum plate is the same. If there is obvious color difference, there may be some quality problems, which may be caused by problems in the production process. Do not buy.
Check the surface of aluminum plate for bulge or depression. If aluminum is produced from regular manufacturers, then its surface is flat and bright. It is not recommended to select this kind of aluminum plate if there are bumps and depressions on the surface.
The aluminum profile can be bent properly. If it can be bent effortlessly, it shows that the strength is not up to the standard. In the use experience, you can start to test whether it meets the specification.
The commonly used models of aluminum profiles are 70 and 90 series, and their thickness should be 1.2mm-2.0mm. You can judge the thickness of aluminum plate according to your specific use.
If there are obvious defects on the surface of the selected aluminum alloy profile, such as open bubble, ash, crack, burr, peeling and so on, it can be explained that this kind of aluminum profile belongs to the secondary processing of recycled aluminum or waste aluminum and is not suitable for purchase. This kind of products generally also have certain quality problems.
The above are the aspects that can be considered in the selection of alloy aluminum plate. Most of these aspects need to be observed by myself, so when purchasing, you can go to the physical store to check and make sure there is no error before you can purchase. It has a wide variety of products, which can be selected by comparison.
