镁铸造合金

[中文适用范围]： 除了将其放入新的 SAE 技术标准委员会格式之外，本文件没有任何变化。该 SAE 标准涵盖了适合通过各种商业工艺铸造的最常用镁合金。显示了化学成分限制和最低机械性能。多年来@镁合金已通过许多编号系统@进行标识，如表1所示。目前@SAE建议使用UNS编号系统来标识这些材料。本标准未涵盖其他同等重要的特性，例如表面光洁度和尺寸公差。 [外文原描述]： This document has not changed other than to put it into the new SAE Technical StandardDetails Board FormatThis SAE Standard covers the most commonly used magnesium alloys suitable for casting by the various commercial processes. The chemical composition limits and minimum mechanical properties are shown. Over the years, magnesium alloys have been identified by many numbering systems, as shown in Table 1 . Presently, SAE is recommending the use of the use of the UNS numbering system to identify those materials. Other equally important characteristics such as surface finish and dimensional tolerances are not covered in this standard.Cross Reference: ASTMB275,ASTMB296,ASTMB557
