| Summary: | Various studies are being conducted on alloying materials for mechanical engineering with various unique elements. In particular, studies have been conducted to improve its properties by including elements such as lithium, zirconium, ytterbium, and erbium in the composition of the aluminum alloy. The article examines the change in the wear resistance ability of alloys in aluminum-silicon and aluminum-copper systems with germanium oxide based on their mechanical properties. The samples were poured into a resistance furnace. In this case, a germanium oxide compound was added to the charge of one to three percent. Wear resistance was determined using a diamond stone meter. At the same time, the samples were measured on the device with the strength of wear resistance at certain intervals. Based on the results obtained, a graph of the dependence of the wear resistance of the samples on the GeO mass was developed. The conclusions of the authors based on the results obtained are given in the final part of the article. The study was tested in the laboratory of the Department of Foundry Technologies of Tashkent State Technical University.
