The so-called aluminum plate is actually metal aluminum, that is, pure aluminum plate, which has only one series, while alloy aluminum plate is divided into multiple series, about seven series, mainly seven series such as 2-8. Aluminum plate There is only one series of pure aluminum plate, one series, the main component is aluminum, reaching more than 99%. After the 2000 series, alloy aluminum plates are mainly used, with other metal elements added. For example, the 2000 series uses copper as the main alloying element.
The 1000 series is a pure aluminum plate. After adding some metal elements, the pure aluminum plate becomes an alloy aluminum plate. The 2000 series generally adds copper elements, and the copper content reaches 5% or even higher.
