Following the first report in which we told about the surface tension of pure metals, this paper informs the experimental results on the surface tension of copper-, iron-, nickel- and cobalt-base alloys containing molybdenum, tungsten, silicon and chromium, as follows: (1) A change of surface tension in a binary alloy system occurs in coincidence with the liquidus line of the melting point diagram. (2) Just upon the melting point,the dissociation of the intermetallic compound seems to be imperfect. (3) The surface tension of alloys containing impure chromium perceptibly decreases with the chromium concentration. This may depend on sulphur and oxygen slightly contained in the samples.
