The Monte Carlo(MC) and Embedded-Atoms Method(EAM) potential are employed to investigate the structures and binding energies of copper clusters. Three results are obtained: first, the copper clusters are formed by gradually increasing atoms to icosahedral surface when the temperature is 300K and the number of atoms is from 2 to 70; second, the higher the symmetries are, the more stable the structures of copper clusters are; third, copper clusters tend to be stereo construction but not planer construction when the number of atoms is less. The structure of Cu147 is three-fly-icosahedron when the system of 147 atoms reached equilibrium at 300K. And at 700K, all 500 atoms form clusters in gas phase.
