Automotive aluminum quality requirements: 1.1 Appearance quality 1.1.1 plate edge should cut Jinan Qi 6082 aluminum shelf, no glitches, 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 per square meter within no more than two scratches Jinan 6082 stock aluminum manufacturers, abrasions at every area of ??not more than 100mm × 100mm. Scratch within the scope of each 500mm × 500mm no more than two, each no longer than 100mm. Classification and use aluminum tubes by shape can be divided into: the tube, pipe, tube markings, Pipes; by kneading method is divided into: seamless tubes, usually kneading tube; divided by Accuracy: Normally tubes, fine tubes, which is usually fine aluminum demand after kneading for reprocessing, such as cold-drawn precision pumping, rolling; divided by thickness: usually aluminum, thin-walled tubes. Aluminum corrosion resistant and lightweight 6082 aluminum spot Manufacturers characteristics, are widely used in various industries, such as: cars, ships, aerospace, aviation, electronics, agriculture, electronics, household and other tubes in our lives now everywhere.
