Abstract

The dynamic viscosities of Cu-Sn alloys with different compositions were measured at the same superheat temperature using an oscillating-cup viscometer. It has been found that the viscosities of Cu-Sn melts increase with decreasing temperature and fit well with Arrhenius equation. At the same superheat temperature, it is found that the viscosity is higher around the phase of β (Cu₅Sn), and the highest at Cu-25 wt%Sn. When the tin concentration is in the range of 20-40 wt%, the average rate of increasing viscosity with the decreasing temperature is faster, and the maximum appears at Cu-25 wt%Sn.
