Abstract
The research aimed at assessing the influence of alloying elements, such as aluminium, silicon, nickel as well as lead and bismuth on the chosen alloys of Cu-Zn. Microstructures were examined with the help of optical and scanning microscopy with X-ray microanalysis. The properties of the received alloys were determined with regard to changes in the chosen 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, within the alloys analysed, 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.
