Abstract: - Series xxx7 alloys are produced from aluminum alloys by adding mainly zinc, Zn, magnesium, Mg, copper, and Cu to aluminum. They have high mechanical properties that distinguish them from other aluminum alloys. In this research, the effect of adding different percentages of nickel [1 0.5, 0.1,] %Wt., and different heat treatments, namely the 6T artificial aging treatment, and the reflux treatment, usually aging and RRA, on the tensile properties, Vickers hardness, and microstructure of aluminum alloy 7075 was studied. Habit of aging. It has been shown that the reflux and RRA treatment gives better results than the 6T artificial aging treatment, and the adding of nickel in general has led to a softer crystalline structure of the studied alloy and higher values of Vickers hardness and tensile properties of the alloy.
