Professional 4x8 aluminum sheet metal supplier Huawei provides high quality aluminum sheet cover 1000 series to 8000 series alloys. Aluminum plate products are rectangular plates rolled from aluminum ingots, which are divided into pure aluminum plates, alloy aluminum plates, thin aluminum plates, medium-thick aluminum plates and aluminum checkered plates. 4×8 aluminum plate is a common aluminum plate size, and the grades of aluminum plate 408 are 1050, 1060, 1070, 1100, 3003, 3004, 3104, 3105, 5052, 5083, 5086, 5454, 5754, 6061, 6063, 7075 and 8011. How to distinguish the quality of 4x8 aluminum sheet metal? 1. Check whether the aluminum plate metal has obvious deformation, and check the appearance of the 1 8 aluminum sheet. There should be no protrusions 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 4x8 aluminum sheet has different shades of color. The color difference indicates that the quality is not high. Of course, contour lines 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 it. Check whether the section thickness of the alloy aluminum plate is the same as the model. 3. You can scratch the metal surface of the aluminum sheet with a smooth hard object, leaving white scratches. Lightly wipe the aluminum plate alloy and observe by hand. If it cannot be wiped off, the material may have quality problems, but if it can be wiped off easily, the oxide film thickness on the contoured surface is acceptable.
