Embodiment Construction

[0034] Such as figure 1 As shown, the present invention discloses a sintering-resistant and cavitation-resistant copper alloy applicable to the manufacture of mechanical parts. Specifically, a sintering-resistant and cavitation-resistant copper alloy, the composition and mass percentage of which are——

[0035] Cu: 64.0% to 72.0%;

[0036] Al: 1.0% to 3.0%;

[0037] Ni: 2.5% to 4.0%;

[0038] Si: 0.5% to 2.0%;

[0039] Mn: 0.5%~2.0%;

[0040] Fe: 0.2% ~ 1.0%;

[0041] The balance is Zn.

[0042] Here, it should be noted that, due to unavoidable reasons in the processing process, certain impurities must be contained in the final product, and the impurities will be referred to by others hereinafter. The composition and mass percentage of impurities in the final product are 0.2% to 0.5%.

[0043] A set of measurement data is listed below to further prove the mechanical properties of the anti-sintering and cavitation-resistant copper alloy of the present invention:
