description: This work is devoted to the study of the causes of a decrease in the electrical conductivity of products made of CuCr1Zr (AERIS 1330) and CuNiSiCr (AERIS 1340) copper alloys, as well as the development of measures to increase electrical conductivity. The research set the following goals: 1. Conduct a statistical analysis of the chemical composition and the charge materials of products with satisfactory and unsatisfactory electrical conductivity; 2. Study microstructure by optical metallography. To determine the structural components affecting the electrical conductivity of alloys; 3. Analyse possible processes that have resulted in structural changes that do not provide the required electrical conductivity. The work was carried out using the accounting records of the melted charge and bronze ingots of the CuCr1Zr (AERIS 1330) and CuNiSiCr (AERIS 1340) brands in the period from November 2023 to February 2024, provided by LLC Â«Astrinsplav SKÂ». The analysis of literature data, including from foreign sources, on bronzes of the brands CuCr1Zr (AERIS 1330) and CuNiSiCr (AERIS 1340) was carried out. A statistical analysis of the chemical composition and charge materials of products with satisfactory and unsatisfactory electrical conductivity was performed, as a result of which a large number of numerical calculations of scattering characteristics were performed and control maps of the individual values of the content of all major alloying elements in copper alloys of the grades CuCr1Zr (AERIS 1330) and CuNiSiCr (AERIS 1340) were constructed. Metallographic analysis of the microstructure of the samples provided by the company was also performed. The result of a statistical analysis of the chemical composition showed that production is extremely unstable. As a result of the analysis of microstructures, a pattern was revealed between the electrical conductivity indicators and the resulting structures. Effective technological recommendations for increasing electrical conductivity have been developed. The results of the research can be applied to improve the production technology used at the company.
