Magnesium ZW10 T1 Cast Alloy，Mg-1.3Zn-0.6Zr,E FOUR

### **Product Datasheet: Magnesium ZW10 T1 Cast Alloy (Mg-1.3Zn-0.6Zr)** **Low-Alloy Magnesium Casting Alloy with Good Ductility and Corrosion Resistance** --- #### **1. Overview** Magnesium ZW10 T1 is a low-alloy sand casting magnesium alloy with a nominal composition of Mg-1.3Zn-0.6Zr. Supplied in the T1 temper (artificially aged after casting), this alloy offers a favorable combination of moderate strength, good ductility, and excellent corrosion resistance. The minimal alloying content makes it one of the most cost-effective zirconium-containing magnesium casting alloys, suitable for applications requiring good overall performance without the need for high strength. --- #### **2.
