Abstract : A binary Al-Zn and five ternary Al-Zn-Cu alloys were produced using stir casting process by varying the Cu contents from 0-5 wt. % and keeping Al content as constant value of 60 wt. %. It was found that the micro-hardness and the ultimate tensile strength of the alloys increases significantly with increasing Cu content up to 2 wt. % which is due to solid solution hardening of Cu content in Al-Zn alloy. Further increase of Cu content results in the formation of hard and brittle θ phase which weakens the inter-dendrite region and marginally increases the hardness and ultimate tensile strength of the alloy. The percentage elongation of the alloy system decreases continuously with addition of Cu content. © Research India Publications.
