ZM6 magnesium alloy has been widely used in aerospace industries in recent yea
rs for excellent castability, mechanical property, corrosion resis
tance and suitability in high temperature conditions compared with the ZM5 and
 ZM1 magnesium alloy. the influences of alloying elements were studied on the ZM6 magnesium alloy properties and mechanical properties. The results show that Zn、 Nd、 Zr have an good strengthening effect for ZM6 magnesium alloy. The best streng thening effect element is Zn. The Zn addition is Zn 0.4%～0.7%， Zr 0.6%～0.7%， Nd 0.4%～0.8%时， The mechanical property value is highest. High purity material and reasonable melting process are important to obtain excellent properties alloys.
