1, Pure aluminum PLATE: pure aluminum Plate series commonly used code has 1050, 1060, 1100. In all aluminum plate series, the pure aluminum plate series belongs to the most aluminum content of a series. The purity can reach more than 99%. Because it does not contain other technical elements, the production process is relatively simple, the price is relatively cheap, is currently the most commonly used in conventional industry series. Most of the current market circulation is 1050 and 1060 series. 2, Alloy aluminum Plate: 2XXX Series Alloy Aluminum Plate: representative of 2A16 (LY16), 2a06 (LY6). 2XXX Series aluminum plate is characterized by high hardness, which is the highest content of copper, probably around $number. 2XXX Series Aluminum plate belongs to aviation aluminum, which is not often used in conventional industry. 3XXX Series Alloy Aluminum Plate: represents 3003 aluminum plate, 3004 aluminum plate, 3A21 aluminum plate. The 3XXX Series aluminum plate is composed of manganese element, content between 1.0-1. A anti-rust function is a good series. Conventional applications in air-conditioning, refrigerators, car bottoms and other humid environment, the price is higher than the 1XXX series, is a more commonly used alloy series.
