The microstructure and properties of chromium bronze, with different chromium content and treatment method, were characterized by using scanning electron microscope, energy‐dispersive X‐ray spectroscopy, transmission electron microscopy and optical microscopy technique. For the specimens with the same treatment method, with increasing of the chromium content, the number of chromium phase increase and the dispersion strengthen effect enhances. On the other hand, the hinder effect on the electrons enhances and the electrical conductivity decreases. For the specimens with same component, the tensile strength and hardness order from low to high are: casting, aging treatment and solution aging. The electrical conductivity order from low to high are: casting, solution aging and aging treatment.
