Abstract: Quality improvement is one of the most important requirement to strengthen a competitive position in our markets. This research aims to study the effect of Cu addition on the behavior of mechanical properties of Aluminum-Copper (Al-Cu) alloy, especially, the value of yield and tensile strength determined by tensile tests. Fatigue tests were also conducted on Al-Cu samples with various copper additions. Al-Cu samples were first cast with different percentages of copper (2, 4 and 8 wt.%) and then machined by a CNC milling to prepare samples for tensile and fatigue tests. The experimental result showed the clear influence of increasing copper percent. It was observed that the increase in Cu% increase the value of tensile strength.
