文章介绍了Al-Mg合金板加工时的三个特点,并提出了最佳工艺和指出在加工时的三个技术问题及找出了解决的办法。Al-Mg系合金板材在软态下具有强度高、韧性好、焊接性佳、质轻的特点,因此在导弹、火箭、船舶、一般民用制品上日益得到广泛的应用。这种铝合金的含Mg量一般在1.5～9.5%之间。目前我国通常应用的 Al-Mg 合金牌号及其化学成份如表1所示。由于含 Mg 的关系,给加工和使用时常带来一些技术问题。
The article introduces the three characteristics of Al-Mg alloy plate processing, and puts forward the best technology and points out the three technical problems in processing and find out the solution. Al-Mg alloy sheet has the characteristics of high strength, good toughness, good weldability and light weight in soft state. Therefore, it has been widely used in missiles, rockets, ships and general civil products. The Mg content of this aluminum alloy is generally between 1.5 to 9.5%. At present, China’s commonly used Al-Mg alloy grades and their chemical composition shown in Table 1. Due to the Mg-containing relationship, some technical problems are often brought to the processing and use.
