Abstract: The proposed study analyzes the problem of copper-nickel alloy inadequate use in the production of art-industrial products. The dynamics of the origin, composition change and alloy treatment method historical development is observed. The study examined the technological, ecological and aesthetic characteristics of copper-nickel alloy-German silver. The analysis of the alloy physical-mechanical properties in the annealed and deformed state is performed, the heat treatment modes are recommended-recrystallization and complete annealing which shall be applied depending on an alloy deformation degree to eliminate an unwanted hardening-cold hardening. The comparative analysis of physical-mechanical properties and the price of nickel silver and silver alloys is performed, its economic viability is revealed. The prospects of nickel silver use are determined in the production of art-industrial goods and design taking into account current technologies and various types of coatings such as silver coating, radioing, the use of cold enamels. The restriction of nickel silver use for jewelry is specified related with the presence of nickel in an alloy, the recommendations concerning performance problem elimination are provided. The classification of art-industrial products of German silver is developed, uniting two groups of products-jewelry and disposable objects.
