The results of surface tension measurements on liquid metals and alloys, performed in microgravity, are presented. Using electromagnetic levitation and the oscillating drop technique, the surface tension of gold, gold-copper, and zirconium-nickel was measured. We find excellent agreement with available results obtained on earth by the same technique, but only if the latter are corrected to account for gravity effects. This not only shows the necessity for the correction of surface tension data derived from earthbound oscillating drop experiments but also proves its correctness.
