The 1000 series aluminum entry sheet has four common aluminum alloys：1000 aluminum entry sheet, 1050 aluminum entry sheet, 1060 aluminum entry sheet, and 1070 aluminum entry sheet, which contain more than 90% aluminum. Since it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in conventional industries. Most of the current market circulation is 1050 and 1060 series. The 1000 series aluminum plate is based on the last two digits to determine the minimum aluminum content of this series. For example, the last two digits of the 1050 series are 50. According to the international brand naming principle, the aluminum content must reach more than 99.5% to be qualified products. For the same reason, the aluminum content of the 1060 series aluminum plate must reach more than 99.6%.
