Abstract

Способ изготовления готового изделия или изделия-полуфабриката из серебряного сплава, включающий в себя стадии обеспечения серебряного сплава, содержащего серебро в количестве по меньшей мере 77 мас.%, медь и некоторое количество германия, которое предпочтительно составляет по меньшей мере 0,5 мас.% и является эффективным для снижения потускнения и/или пятнообразования в пламени, изготовления или обработки готового изделия или изделия-полуфабриката из этого сплава путем нагревания, по меньшей мере, до температуры отжига, постепенного охлаждения этого изделия и повторного нагревания этого изделия для осуществления его дисперсионного твердения. Исключение закалки снижает риск повреждения изделия.A method of manufacturing a finished or semi-finished product from a silver alloy, including the steps of providing a silver alloy containing at least 77 wt.% silver, copper and an amount of germanium, which is preferably at least 0.5 wt.% and is effective in reducing tarnish and/or flame staining, making or processing a finished or semi-finished product from the alloy by heating to at least annealing temperature, gradually cooling the product, and reheating the product to age harden it. . Eliminating hardening reduces the risk of damage to the product.
