Copper nickel alloys are widely used in differential industries due to their special mechanical and chemical properties, today copper and its alloys remain on of the major groups of commercial metals ranking, third behind only steel and aluminium in production and consumption. The present work was attempt to study and investigate the effect of cold working and heat treatment on the mechanical properties of copper nickel alloys reaching to estimate the effect of these work conditions on the copper nickel alloys performance. . The results indicated that cold working increase the mechanical properties, while it’s been controlled if the cold working applied tighter with the heat treatment. The experimental result show the effect of cold working and heat treatment and on the tensile strength and Brinel hardness of the three grade of copper nickel alloys (90%Cu: 10%Ni), (80%Cu: 20%Ni), and (70%Cu: 30%Ni).

Keywords: Copper nickel alloys, cold working, heat treatment, etc.
