Sažetak

One of the basic parameters that characterize a liquid phase is its viscosity. In the paper, the results of viscosity measurements for copper, copper-zinc alloys with 5 %wt. Zn and 10 %wt. Zn as well as Cu-Zn alloys with small additions of antimony, selenium and sulfur are presented. The viscosity measurements were conducted by means of a viscometer using the phenomenon of damping rotational vibrations of the crucible by filling the liquid metal. It was observed that the additions of zinc, antimony and selenium resulted in the viscosity reduction while the addition of sulfur led to its increase.
