These investigations included microstructural characterization and experimental determination of hardness, microhardness and electrical conductivity. Microstructure of the investigated alloys has been done by light optical microscopy. In the frame of investigations of some mechanical properties, hardness and microhardness were determined by Vickers standard method. Electrical conductivity was determined too. Experimental investigations of CuAlAg alloys with 70 at%Cu eng
