AB  - Purpose– This paper seeks to investigate the effect of roller burnishing on the surface roughness and hardness of Zn−5% Al alloyed by copper at varied percentages.Design/methodology/approach– Copper was added to molten Zn−5%Al cast alloy at different percentages, then the roller burnishing process with different parameters was carried out on the five Zamac5−Cu alloys, however the effect on the surface roughness and hardness was investigated.Findings– It was found that there is an enhancement on the hardness and the maximum is 18 per cent in Zamac5−10% Cu alloy. The best surfaces result was 0.05 μm that obtained at 0.04 mm rev −1 burnishing feed rate in Zamac5−10% Cu alloy.Originality/value– The addition of copper is recommended to be added to Zamac5 up to percentage of maximum solubility of copper in Zamac5 alloy.
