The effects of heat-treatment on microstructure and properties of multi-element micro-alloying aluminum-bronze alloy and strengthening mechanics were studied. The better process for solution-aging tratment was confirmed. The results show that the tensile strength, hardness and impact ductility is up to 608 Mpa, 40.8 HRC and 4.8 J/cm~(-2) after 960℃×2 h solution (cooling in water)+520℃× 3 h aging (cooling in air).
