This paper deals with on the investigation of surface topography, morphology and anisotropy of copper alloys - brass and bronze, created by pulsating water jet with frequency 20.38 kHz. The material was disintegrated using more passes of a pulsating water jet using flat nozzle, at pressure 40 MPa and stand off distance z = 55 mm. The average values of Ra, Rq, Rz roughness were analyzed at changing traverse speed and number of transitions. The effect of tensile strength and material hardness as mechanical properties of material affecting the average value of the roughness has been evaluated. It is assumed that this new way of metal eroding can be used in the automotive and engineering industries in the future e.g. for surface treatment.
