The results show that, when the electromagnetic field was applicated, the flowability and filling capacity of cupronickel alloy are increased, the surface cracks are eliminated, and the thin-walled cupronickel tube billets with smooth surface can be obtained due to the increase of flowability and filling capacity of cupronickel alloy. The solidification structure of the tube billets is evidently refined, the shape of Ni-rich phase changes from needle-like to bulk and the casting stress declines from 7.2 to 0.32 MPa. With the structure improving, the tensile strength and elongation increase by 5% and 36%, respectively, than those of ordinary continuously cast tube billets.
