Abstract
The invention discloses a Cu-Al-Ti-Fe-Ni system copper alloy which consists of the following ingredients by weight percentage: 6-10% of Al, 2-7% of Ti, 2-5% of Ni, and 2-3% of Fe, with the balance being Cu. A preparation method of the copper alloy comprises the following steps of a. weighing raw materials, b. carrying out compacting and c. performing vacuum melting, wherein in the Step a, the raw materials are weighed according to the weight percentage, and mixed; in the step b, the mixed raw materials are placed in a model cavity and compacted; and in the step c, the compacted raw materials are placed in a vacuum arc melting furnace with the vacuum degree of 5*10<-3> to be melted. The copper alloy is characterized in that a copper-based solid solution and a Cu-Al-Ti-Fe-Ni mixed phase exists in a microstructure of the copper alloy. The copper alloy can be significantly strengthened due to precipitation of the Cu-Al-Ti-Fe-Ni mixed phase, and the compressive strength of the copper alloy reaches 1300-1500MPa. Thus, a new material is provided to the power industry, the shipbuilding industry, the refrigerating industry, etc.; and considerable economic benefits are brought.
