Excitation functions of the  nat Ni(α,x) 60,61 Cu and  64 Ni(α,p) 67 Cu reactions were measured using the stacked-foil activation technique. The experimental data achieved were compared with literature data as well as with nuclear model calculations performed using the code TALYS-1.8. Integral yields from the respective thresholds to 44 MeV were deduced from the measured excitation curves. The &gt;99% pure  61 Cu can be produced using the energy window of E α =20→7 MeV, the yield amounting to 116 MBq/μAh. After a 2 h cooling time, the short-lived  60 Cu (T 1/2 =23 min) impurity will be reduced to &lt;0.1%. Due to low isotopic abundance of  64 Ni, the enriched  64 Ni target would be needed for the production of  67 Cu via the (α,p) reaction. The cost would, however, be very high. In a few cases, particularly above 24 MeV, we have given new data points. In general, our measurements have strengthened the database.
