<p>The development of technologies for the production of long-length deformed semi-finished jewelry products made from new precious metal alloys that meet European safety requirements is an urgent task given high competition and varying domestic and international market conditions. In this study, 585 (14 K) white gold and 925 (sterling) silver alloys were used. The author-developed software tools were used to design the reduction schedules for these alloys during shape rolling and drawing of long-sized semi-finished products. In addition, the DEFORM 3D software package was used to model the deformation treatment processes. By employing respective planning and regression analysis methods, formulas were obtained for calculating the strength properties of deformed semi-finished products obtained from the studied alloys, which were used to design and model their treatment processes. Experimental studies of the processes of shape rolling of rods and drawing wire made from the studied alloys were carried out in the laboratory. The obtained results confirmed the adequacy of the computer models. The developed technologies are recommended for implementation in production, as they can reduce the labor intensity of the production and improve the quality of finished products, as well as increase the yield and reduce the defect ratio when manufacturing jewelry products.</p>
