FIELD: noble metal alloys. SUBSTANCE: known silver alloy 800 C has, wt. -% silver 79.7-80.2, and copper 19.8-20.3. Proposed alloy has, wt.-% silver 80.0-80.5; copper 17.3-18.2, and nickel 1.8-2.2. Nickel addition and component ratio used provided increased plasticity of alloy (relative elongation) by 2.3-2.4 times, decreased flaw by casting by 23-25% and that by stamping operations by 2.1-2.3 times. EFFECT: enhanced quality of alloy. 1 tbl
