Abstract—Phase diagrams copper–element–oxygen and potential–pH diagrams are plotted for alloys of the Cu–Al, Cu–Si, and Cu–Sn systems at 25C. Thermodynamic peculiarities of the corrosion and electrochemical behavior of phase components of aluminum, silicon, and tin bronzes are analyzed. The surface activity of alloying elements is assessed.
