The Use Of Electroplating Copper-aluminum Alloys To Increase The Tensile Strength Of Copper Wires

The purpose of our project was to discover the effect of voltage in electroplating metals on the resulting tensile strength of the metal rod. We proved our hypothesis correct, that higher voltages did produce lower tensile strengths. We proved this by electroplating, onto thin copper wires, both pure copper and a copper-aluminum alloy. We then used the Buster® machine to stretch and break the wires and recorded the pressure at which the wires broke. The use of our alloys may be applied to many structures including motor vehicles.
