合金鋁板在加工時添加了一些金屬材料，通過添加這些金屬材質就能讓鋁板具有一定的強度，提高了它的使用性能，強度、質量、硬度都會得到提升。因此在一些工業生產的領域應用比較廣泛，使用比較多。
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.
隨著它的使用越來越多，在購買時市面上的鋁板種類也比較豐富，讓消費者看的眼花繚亂，種類多也就意味著它的質量可能會參差不齊，因此在挑選時需要格外注意。那么它的挑選要注意什么呢?接下來就讓我們一起來看一下。
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
在挑選合金鋁板的時候，可以輕劃一下型材的表面，看看是否可以擦掉它的氧化膜，如果能擦掉就說明鋁板的后期處理不好，不建議購買。
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
相同的一塊鋁板色澤也是一樣的，如果有明顯的色差，就可能會存在一定的質量問題，可能是生產過程中存在的問題導致的，就不要選購。
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
檢查鋁板表面有無鼓出或者凹陷跡象。如果鋁材產自正規廠家，那么它的表面是平整而光亮的。如果表面有凸起凹陷不建議選擇這類鋁板。
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、強度
4、 Intensity
可以將鋁型材適當彎曲，如果毫不費力就可將其折彎，那就可以說明，強度不達標。在使用體驗時就可以上手試一下是否符合規范。
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
鋁型材常用的型號為70、90系列，其厚度應該在1.2mm-2.0mm?？梢愿鶕约壕唧w的使用情況來判斷選擇的鋁板厚度。
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、光澤度
6、 Glossiness
如果所選鋁合金型材表面有開口氣泡、灰渣、裂紋、毛刺、起皮等等明顯缺陷的話，可以說明這類鋁型材屬于回收鋁或廢鋁的二次加工，不宜選購。這類產品一般也會具有一定的質量問題。
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.
?以上就是在挑選合金鋁板時可以考慮的方面，這些方面大多是需要本人親自上手觀察的，所以在購買時可以去實體商店進行檢測查看，確保無誤后就可以進行購買。它的種類豐富，可以貨比三家進行挑選。
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.
