Calculation Method for Aluminum Content in Pure Aluminum Plates

　　The Pure Aluminum Plate series determines the low aluminum content based on the last two Arabic numerals, such as the 1050 series, where the last two digits are 50. According to the international brand naming principle, the aluminum content must exceed 99.5% to be considered a qualified product. Our country's aluminum alloy technical standards (gB/T3880-2006) also explicitly state that the 1050 series must have an aluminum content of 99.5%. Similarly, the aluminum content of the 1060 series aluminum plates must exceed 99.6%.
