Viscosities of molten Al(1-x)Mgx (0≤x≤0.10) alloys have been measured in the temperature range of 973 K―1173 K by a torsional oscillation cup method. The viscosity dependence on temperature for Al(1-x)Mgx (0≤x≤0.10) melts obeys Arrhenius equation. The viscosity increases with increasing mag-nesium concentration in the investigated system. There is an important relationship between viscosity and its glass-forming ability for metallic melt.
