The thickness, strength, and thickness of the oxide film should be in accordance with national standards based on the thickness and quality of the striped aluminum plate. The thickness of the aluminum plate is ≥1.2mm, the tensile strength is ≥157 N / mm2, and the yield strength is ≥108 N / mm2 , The thickness of the oxide film is ≥10 microns. If it does not meet the standard, it is a poor quality marking aluminum plate.
Look at the processing, the streaked aluminum plate produced by a regular large factory, the materials are exquisite, the surface is bright and clean, the streaks are clear and neat, the aluminum plate is flat, and the surface is free of oil stains, scratches, and other shortcomings; while the streaked aluminum plate produced by a small factory uses waste aluminum. Made of material, the surface is dull and dull, the markings are not clear and uneven, the surface of the board is uneven, the performance is not up to standard, and the quality is poor.
Depending on the price, the striped aluminum plate is divided into two types: pure aluminum and alloy, and its price is naturally different. The processing fee for a striped aluminum plate produced by a regular manufacturer is several thousand yuan per ton. The price of the alloy is higher than that of pure aluminum. The price of the aluminum plate of a regular manufacturer is about 20% -30% higher than that of the inferior aluminum plate. When purchasing, the company must not compare the price and buy the unqualified products.
