本文件除纳入新的SAE技术标准委员会版式外未作任何更改。本SAE标准涵盖了适用于各种商业工艺铸造的最常用镁合金。显示了化学成分极限和最低机械性能。多年来，镁合金已被许多编号系统识别，如表1所示。目前，SAE建议使用UNS编号系统来识别这些材料。本标准不包括其他同样重要的特性，如表面光洁度和尺寸公差。

This document has not changed other than to put it into the new SAE Technical Standards 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.
