Abstract: Replacement of the bronze grades with beryllium type CuCo2Be and CuBe2CoNi as per SR ISO: 1993 with alloys type CuNi3SiMn and CuNi4AlSi, elaborated was for the first time in the country at I.N.C.D.F. Iasi; The alloys achieved are compatible with CuCo2Be and CuBe2CoNi as it concerns the  mechanical- electrical characteristics and the behaviour in service; The bronzes of replacement are more profitable, they are not noxious during the elaboration or machining; CuNi3SiMn tested for the manufacture of the contact electrodes and CuNi4AiSi for elastic membranes, obtaining results comparable with those of the classic materials; At CuNi4AlSi the thermal-mechanical treatment has been applied – the increase of the hardness with at least 15–20 HV units and the reduction of the ageing time.
