How to distinguish the quality of 4×8 aluminum sheet metal?
1, It is necessary to see whether the aluminum sheet metal has obvious deformation, check the appearance of the aluminum sheet, there should be no bumps or protrusions. Whether the surface is smooth and flat, whether there are cracks or discs, scratches, burrs, if found, it is best not to buy.

2, Carefully check whether the surface color of the 4×8 aluminum sheet has different color shades, the color difference indicates that the quality is not high. Of course, contours of the same type can also be combined for comparison. Of course, if the color difference is too obvious, it is best not to buy. Check whether the section thickness of the alloy aluminum plate is the same as the model.

3, You can use a smooth hard object to scratch the surface of the aluminum sheet metal, leaving white scratches. Gently wipe the aluminum sheet alloy and observe it by hand. If it cannot be wiped off, the material may have quality problems, but if it can be wiped off easily, it indicates that the oxide film thickness on the contour surface is acceptable.
