Abstract: At the liquid state, on the diagrams (above the line of liquidus), an identical field of liquid solution is usually presented not depending on the type of the diagram of state of solid metal. However, these last years a series of works appeared which directly shows the well defined relation ship of the control of the liquid and the variation of these properties (viscosity, surface tension, conductibility electric and different) with the nature and the type of the diagram of state, these characteristics finds an image and emerges from the lines, dividing the common pole of the liquid state on various fields, which is characterized a dependent given energy with the particles of the components thus binding the various properties of liquid alloy. The properties of alloys containing copper in the liquid state are studied in several researches. However, currently, the volume of information is not sufficient for all the characteristics of these alloys. The number of the data on the density, viscosity, surface tension and other physicochemical properties of liquid copper alloys did not find for the moment of use practical. In this present work, we studied the most important physicochemical properties of principal liquid alloys containing copper (Cu-Pb, Cu-Si, Cu-Al).
