The viscosity of Al$_{1-x}$Ni$_{x}$ ($x$ = 0.025; 0.05 and 0.075) molten alloys has been studied by means of oscillating crucible method. The temperature dependence of dynamical viscosity coefficient is obtained and activation energy is estimated from them. The analysis of concentration dependence of viscosity coefficient reveals its deviation from linear dependence. Significant increase of viscosity coefficient for liquid aluminum upon the addition of Ni-atoms is caused by cluster formation and increase of their size.
