1、就是要看6061鋁板是否有明顯的變形，表面是否平整光滑，有無裂紋或粗大、劃痕、毛刺的地方，如果發現有更好不要購買。
　　1. It is to see whether 6061 aluminum plate has obvious deformation, whether the surface is flat and smooth, whether there is crack or rough, scratch or burr. If it is found, it is better not to buy.
　　2、是仔細檢查鋁合金表面是否有不同色度的顏色，色差意味著質量不合格。當然，你也可以把同類型的型材放在一起比較，當然，如果色差太明顯，更好不要選擇。檢查合金鋁板的截面厚度是否與標注的型號一致。
　　2. Carefully check whether the surface of aluminum alloy has different color. Color difference means the quality is unqualified. Of course, you can also compare the same type of profiles together, of course, if the color difference is too obvious, it is better not to choose. Check whether the section thickness of the alloy aluminum plate is consistent with the marked model.
　　3中,您可以使用光滑的硬東西劃傷的表面合金鋁板,將一個白色,6061鋁板用手輕輕擦拭,觀察,如果你不能抹去,表明材料的質量可能有問題,但是相反,如果你很容易擦掉,表明剖面表面氧化膜的厚度是合格的。

　　In 3, you can use the surface alloy aluminum plate scratched by smooth hard things, wipe a white and 6061 aluminum plate gently by hand, observe, if you can't wipe it off, it indicates that there may be a problem with the quality of the material, but on the contrary, if you easily wipe it off, it indicates that the thickness of the oxygen film on the surface of the profile is qualified.
　　對于市場上質量較差的機械框架合金鋁板，消費者可以用一種簡單的方法來識別合金鋁板，讓您在使用時更好。
　　For the mechanical frame aluminum alloy plate with poor quality in the market, consumers can use a simple method to identify the aluminum alloy plate, so that you can use it better.
