Firstly, Cu-Al alloy was doped with selected elements of Fe, Mn and Ni, and Cu-Al-Fe-Mn-Ni alloy, after being synthesized by adopting hot-pressing sintering process respectively at different temperatures, was subjected to solution-aging treatment. The microstructure of the alloy was characterized by means of metallographic microscope, scanning electron microscope, X-ray diffractometer among others, and the density, hardness and electrical conductivity of the alloy were tested. It is found that at a low temperature (750 ℃), the synthesized alloy has lower density, around 7.946 g/cm³, and poor mechanical properties, with Vickers hardness of 253.9HV. Both density and hardness of the alloy increase with the rise of temperature. At 950 ℃, the density increases to 8.058 g/cm³ and the Vickers hardness rises to 281.5HV. But the hot-pressing sintering temperature hasn' t significant impact on the electrical conductivity of the alloy. The solution-aging treatment can improve the density of the alloy. Meanwhile, solution treatment leads to slight reduce in the hardness and electrical conductivity of the alloy, while aging treatment brings the reverse effect.
