Effects of the solid solution and aging treatment on microstructure, hardness and electrical conductivity of the Cu alloy containing 1.1 wt% Cr were investigated. The Cu-Cr alloy contains Mn as an alloying element. The horizontal continuous casting process was applied to obtain the unidirectionally solidified billets. The solid solution treatment of the alloy was carried out at 990 oC and the aging treatment was performed in the range 420-520 oC. The electrical conductivity generally increased as the aging temperature increased from 420 oC to 520 oC.
