Abstract: In order to develop copper-aluminum composite materials, a new equipment of continuous core filling cast for the bimetal composite materials of copper cladding aluminum was designed and produced, The characteristics of the new equipment were that, the crystallizer was composed of water jacket copper sleeve in which graphite sleeve was set; two melting furnaces with different diameters were vertically distributed, and the low furnace of melting copper was linked the crystallizer; and continuous casting and core filling were proceeded at the meantime. The bimetal composite of copper cladding aluminum was made successfully with the diameter of aluminum of Ф24 mm and the thickness of copper of 8 mm.
