Characteristically appear as dark (grey or black) rough patches, at regular or random intervals along the extruded length. If the defective sample is etched in a 10% NaOH etching solution at 60°C a heavy black smut will be observed in the area of the hot spot. Defect cause:This is 5182 Aluminum Plate VS Steel Plate - aluminum alloy priceFrom the market feedback, the processing performance and stamping effect of the 5182 alloy aluminum plate performed well, and the aluminum plate was punched without cracking. 2, 5182 aluminum plate is light in weight and can reduce the weight of the car. The density of aluminum is about 1 Hot Chinese Style Environmental Etch Aluminium Alloy Plate3 of that of steel plates. Anodizing of Aluminum - FinishingThe great majority of aluminum anodizing is done with room temperature (20 °C 68 °F) sulfuric acid (approximately 15% by weight, 10% by volume) at 10-20 volts. Depending on for how long the work is processed, and the specific aluminum alloy being anodized, this produces an anodizing thickness from about .0001" to .0008" thickness.
