好的铝材应该从哪些方面鉴别？

1、看外观和断面。假如外观和断面光亮,就注解铝材的合金成分高,比较纯。假如是断面发黑，或者说外观色泽不光亮百度搜索排名，就注解这种铝材是用回收料做的。
1. Look at the surface and the cross section. If the surface and section are bright, it indicates that aluminum alloy has high composition and purity. If the section is black, or the surface is not bright, it indicates that the aluminum material is made from recycled materials.
2、看强度。用两种铝材，好料和次料碰撞，好的料不会有太大的磕迹，坏的料就会沉下去一个沟槽。
2. Look at the strength. With two kinds of aluminum materials, good material and secondary materials, the good material will not have too much knock, and the bad material will sink into a groove.

3、看报价。材质不一样，外观处理不一样活动策划公司，铝材的壁厚不一样，报价就不一样北京人事考试中心，差很远。假如报价低的，多半是次料回收，壁厚太薄，同样1米，人家重4KG的，它才两公斤多,人家壁厚是5MM的,它才1.2MM。

3. Look at the quotation. The material is different, the surface treatment is not the same, the wall thickness of aluminum is different, the quotation is not the same, far from it. If the price is low, most of the material is recycled, the wall thickness is too thin, the same 1 meters, and the 4KG is only two kilograms. The wall thickness is 5MM, and it is only 1.2MM.
