Effect of Mn and Cu Content on Microstructure and Properties of Zn-Al Alloys

Effect on mechanical property and microstructure of Zn-Al alloys added different content Mn and Cu were studied. The results showed that the mechanical property of Zn-Al alloy was no effect notably under adding a samll content Mn and Cu. With the increasing of Mn and Cu content in the alloys,the hardness of the alloys had increased greatly,and the impact toughness of the alloys did not almost change.
