The purpose of current paper is production of Copper-Aluminum bimetal by using centrifugal casting and evaluation of Copper-Aluminum interface and also optimization for creating metallurgical interface with appropriate and minimum discontinues between metals interface. In this research the solidification time of primary layer is calculated on base of chornief relation and second melt after different timescales that changed the interface temperature, was casted. The background structure, elements diffusion and hardness depending on the temperature of casted copper in a mold and Aluminum casting with different primary Copper bases in 100°C, 200°C, 300°C, 500°C is evaluated. The results are shown that by decreasing temperature, brittle intermetallic structures losse and hardness decrease. Two things are important for creation of complete metallurgical bonding between two metals, first the Copper temperature before Aluminum decanting and second is the lack of impurities and metal oxides in bonding.
