				 In the paper, results of a study on the effects of deformation conditions (temperature, strain and strain rate) on flow curves, maximum flow stress and corresponding deformation of Cu-Ti alloys with various Ti contents, subjected to hot deformation, are presented. Evaluation of formability of alloys was performed with the use of a Gleeble HDS-V40 thermal-mechanical simulator during uniaxial hot compression at 700 to 900°C, strain rate of 0.1 to 10.0 s -1  and strain of 0 to 1.2 (70%). It was found that within the analysed ranges of temperature, strain rate and strain, Cu-Ti alloys underwent uniform deformation without cracking. The largest deformation resistances were observed for the alloys with the highest Ti contents; their decrease was possible with the temperature raise and the strain rate reduction.
