    The research aimed at assessing the influence of alloying elements, such as Al, Si, Ni, Pb and Bi on the chosen alloys of Cu-Zn. Microstructures were examined with the useof optical and scanning microscopy with X-ray microanalysis. The properties of the received alloys were determined with regard to changes in the mechanical parameters, namely $R_{m}$, $A_{5}$, HB, also, machinability changes were assessed as well as proclivity to hot fracturing of Cu-Zn alloys with additives of lead and bismuth. The results indicate the possibility of obtaining very high mechanical properties: $R_{m}$ up to 700 MPa, hardness within the range of 130-180 HB and $A_{5}$ from 3 to 30%. Also, in the case of the researched alloys, the machining and hot fracturing results look promising.
