Abstract: This paper investigates the effects of process annealing on the mechanical properties of strain ‎hardened copper from Kabel Metal Nigeria Limited. The results obtained showed that ‎hardness of copper during cold rolling increases with degree of deformation due to strain ‎hardening. The maximum value of hardness obtained was 117 HB at 40% reduction in area, ‎while the average hardness values obtained after annealing temperatures of 3000C, 4000C and ‎‎5000C were 79.2, 67.2 and 45.7 HB respectively. During tensile test, the cold-rolled copper ‎fractured with very little elongation. The maximum ultimate tensile stress obtained was 188.4 ‎N/mm2 at 20% reduction in area. Anneal strengthening effect which increases with increasing ‎degree of prior cold work was observed in the copper‎
