合金铝板在加工时添加了一些金属材料，通过添加这些金属材质就能让铝板具有一定的强度，提高了它的使用性能，强度、质量、硬度都会得到提升。因此在一些工业生产的领域应用比较广泛，使用比较多。
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.
随着它的使用越来越多，在购买时市面上的铝板种类也比较丰富，让消费者看的眼花缭乱，种类多也就意味着它的质量可能会参差不齐，因此在挑选时需要格外注意。那么它的挑选要注意什么呢?接下来就让我们一起来看一下。
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.
一、氧化度
1、 Oxidation degree
在挑选合金铝板的时候，可以轻划一下型材的表面，看看是否可以擦掉它的氧化膜，如果能擦掉就说明铝板的后期处理不好，不建议购买。
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.

二、色度
2、 Chroma
相同的一块铝板色泽也是一样的，如果有明显的色差，就可能会存在一定的质量问题，可能是生产过程中存在的问题导致的，就不要选购。
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.
三、平整度
3、 Flatness
检查铝板表面有无鼓出或者凹陷迹象。如果铝材产自正规厂家，那么它的表面是平整而光亮的。如果表面有凸起凹陷不建议选择这类铝板。
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.
四、强度
4、 Intensity
可以将铝型材适当弯曲，如果毫不费力就可将其折弯，那就可以说明，强度不达标。在使用体验时就可以上手试一下是否符合规范。
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.
五、厚度
5、 Thickness
铝型材常用的型号为70、90系列，其厚度应该在1.2mm-2.0mm。可以根据自己具体的使用情况来判断选择的铝板厚度。
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.
六、光泽度
6、 Glossiness
如果所选铝合金型材表面有开口气泡、灰渣、裂纹、毛刺、起皮等等明显缺陷的话，可以说明这类铝型材属于回收铝或废铝的二次加工，不宜选购。这类产品一般也会具有一定的质量问题。
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.
以上就是在挑选合金铝板时可以考虑的方面，这些方面大多是需要本人亲自上手观察的，所以在购买时可以去实体商店进行检测查看，确保无误后就可以进行购买。它的种类丰富，可以货比三家进行挑选。
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.
