Abstract The viscosity of Cu melt is obtained to be in the ranges from 2.418 to 3.039 mPa.s under vacuum atmosphere (2Pa), from 2.907 to 3.425 mPa.s under nitrogen gas atmosphere and from 3.352 to 4.015 mPa.s under argon gas atmosphere. The activation energy is estimated to be 0.224, 0.162 and 0.150eV for the vacuum atmosphere (2Pa), nitrogen gas atmosphere and argon gas atmosphere, respectively. The results reflect the essential structural change in the Cu melt by using different atmospheres.
