The invention provides a copper alloy rotor slot wedge with excellent high temperature performances and a good extrusion moulding property, and a production method thereof. The copper alloy rotor slot wedge is characterized by being composed of the following elements in percentage by weight: 1.6 to 2.5 wt% of Ni, 0.05 to 0.15 wt% of C, 0.5 to 0.8 wt% of Si, 0.15 to 0.25 wt% of Zr, and the total content of Ni, C, Si, Zr and Cu is not less than 99.5 wt%. The provided slot wedge has excellent high temperature performances especially the high temperature elongation rate. The plasticity of the slot wedge is excellent at a high temperature around 850 DEG C. The rotor slot wedge can be produced through an extrusion or drawing technology so as to replace the original forging technology.
