Microstructure and mechanical properties of the manganese-aluminium bronze (SUPERSTON alloy) used in ship propeller's production can be changed by the heat treatment, including hardening and tempering. In the paper is performed an influence of hardening and tempering temperature on the microstructure, microhardness and corrosion characteristics of the SUPERSTON alloy. The microstructure of the SUPERSTON alloy as a casting and after heat treatment is characterized by measure-ment of the HV0.05 and LM, SEM as well as AFM observations. On the base of potentiostatic corrosion test results is con-cluded that the best corrosion characteristics of the SUPERSTON alloy are obtained after hardening from 900°C and tempering 550°C, in comparison to heat untreated {as casting) copper alloy.
