1XXX Pure Aluminum Description 1XXX Series Representative 1050 1060 1070 1XXX series aluminum plate is also called pure aluminum plate. In all series, 1XXX series belongs to the series with the most aluminum content. The purity can reach above 99.00%. Because 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 the conventional industry. Most of the current circulation on the market is the 1050 and 1060 series. According to the last two Arabic numerals, the 1XXX series aluminum plate determines the minimum aluminum content of this series. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand nomenclature, the aluminum content must reach 99.5% to be qualified products.
