Automotive aluminum quality requirements: 1.1 Appearance quality 1.1.1 plate edge should be cut flush, burr, crack edge, does not allow stratification. Within the scope of the strip on both sides of 30mm or 30mm around the plate within the range allowed a variety of non-critical defects. 1.1.2 The plate should be a good surface quality and processing should be flat, smooth, does not allow cracks, corrosion, wear vent, crimping, creasing, straightening roll printing, peeling, annealing oil spots and rub scratches, oil, sticky injury, prints, loose dendritic pattern, metallic and non-metallic objects push other defects. Allow a slight light bar does not affect the use of color and other defects. 1.1.3 requires deep drawing sheet metal without the "flow pattern" and "orange peel" phenomenon after deep drawing. 1.1.4 plate, strip surfaces rub, scratch deeper than 0.02mm. Rub scratches per square meter within no more than two, each area of ??the abrasion does not exceed 100mm × 100mm. Scratch within the scope of each 500mm × 500mm no more than two, each no longer than 100mm. Mechanical properties of aluminum car Specifications: 1.1 mechanical properties at room temperature tensile properties sheet specimens shall conform to GB / T 16865's. Test methods according to the provisions of GB / T 228 will be. 4.4 Tensile strain hardening exponent (n value) stretch panels hardening exponent (n value) of the sample and test methods shall be in accordance with the strain GB / T 5028 requirements. 4.5 plastic strain ratio (r values) sheet of plastic strain ratio (r value) of the sample and test methods shall be in accordance with the provisions of GB / T 5027's. How to identify quality alloy aluminum sheet? 1, is to see if there are significant aluminum alloy twist, the surface is smooth, there are no cracks or boldness aluminum production process, scratches aluminum, aluminum burrs establishment where the filter, if any, it is best not found purchase. 2, is to carefully check whether the aluminum alloy surface color in different shades of color, there is color that shows the quality, but off. Of course, the same model can also put together profiles were compared, of course, if the color is best not to buy too obvious. To check whether the thickness of the aluminum alloy cross-section and marked with the same model.
