鋁卷在我們的生活中被廣泛使用，各方面的性能可見的好，但是面對市面上數量繁多的鋁卷，質量方面是不一樣的，有好有壞，那么如何通過外觀厚度來辨別鋁卷質量呢？
　　Aluminum coil is widely used in our life, the performance of all aspects of the visible good, but in the face of a large number of aluminum coil on the market, the quality is not the same, there are good and bad, so how to identify the quality of aluminum coil through the appearance of thickness?
　　鋁卷的質量可以通過外觀，平面度和厚度公差來區分。優質鋁卷表面無油，無色差和劃痕，這可以通過購買鋁卷的外觀來區分，因此建議沒有購買鋁卷經驗的用戶可以通過很簡單的表面來區分鋁卷的質量。
　　Aluminium coil quality can be distinguished by appearance, flatness and thickness tolerances. High quality aluminum coil surface oil free, no color difference and scratch, which can be distinguished by buying the appearance of aluminum coil, so it is recommended that users who do not buy aluminum coil experience can distinguish the quality of aluminum coil by very simple surface.
　　鋁卷生產廠家提醒大家，選擇高質量的鋁卷或展平鋁卷，散布在地面上，可以看到鋁卷是否有起伏的波浪。高質量的鋁卷已得到糾正，沒有明顯的波紋。厚度需要使用的千分尺進行測量。完成上述步驟后，您可以選擇優質鋁卷。
　　Aluminum coil manufacturers remind you to choose high-quality aluminum coil or flat aluminum coil, scattered on the ground, you can see whether the aluminum coil has ups and downs. High quality aluminium coil has been corrected without noticeable ripple. The thickness should be measured with a professional micrometer. After completing the above steps, you can choose high quality aluminum coil.

　　此外，陽極氧化后的鋁卷表面存在許多空隙，如果未密封或密封不好，則鋁型材的耐腐蝕性會降低。鋁的表面易于自然產生致密而牢固的保護膜，可以很好地保基材不受腐蝕。通過人工陽極氧化和著色，可以獲得具有良好鑄造性能的鑄造鋁合金或具有良好加工塑性的變形鋁合金。
　　In addition, there are many voids on the surface of the anodized aluminum coil, and if it is not sealed or poorly sealed, the corrosion resistance of the aluminum profile will be reduced. The surface of aluminum is easy to naturally produce a dense and strong protective film, which can well protect the base material from corrosion. By artificial anodic oxidation and coloring, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can be obtained.
