Description

Изобретение относится к области металлургии, а именно к составам сплавов, которые могут быть использованы в ювелирном деле.The invention relates to the field of metallurgy, and in particular to alloy compositions that can be used in jewelry.

Известен сплав, содержащий, мас. %: золото 33,0-90,0; цинк 0,01-25,0; медь и примеси - остальное [1].Known alloy containing, by weight. %: gold 33.0-90.0; zinc 0.01-25.0; copper and impurities - the rest [1].

Задачей изобретения является упрощение технологии получения ювелирного сплава, расширение ассортимента.The objective of the invention is to simplify the technology for producing jewelry alloy, expanding the range.

Технический результат достигается тем, что ювелирный сплав, содержащий золото, цинк, дополнительно содержит железо и галлий, причем компоненты находятся при следующем соотношении, мас. %: золото 33,0-91,6; цинк 8,5-19,5; железо 0,5-1,5; галлий 1,0-4,0.The technical result is achieved in that the jewelry alloy containing gold, zinc, additionally contains iron and gallium, and the components are in the following ratio, wt. %: gold 33.0-91.6; zinc 8.5-19.5; iron 0.5-1.5; gallium 1.0-4.0.

В таблице 1 приведены составы ювелирного сплава.Table 1 shows the composition of the jewelry alloy.

В составе сплава компоненты проявляют себя следующим образом. Галлий увеличивает пластичность сплава, препятствует окислению, цинк повышает прочность, железо незначительно повышает твердость.In the composition of the alloy, the components manifest themselves as follows. Gallium increases the ductility of the alloy, prevents oxidation, zinc increases strength, iron slightly increases hardness.

Сплав выплавляют в электропечах. В разогретый тигель вводят компоненты, расплавляют их и перемешивают. Разливку сплава производят в стальную изложницу.The alloy is smelted in electric furnaces. The components are introduced into the preheated crucible, melted and mixed. The alloy is cast in a steel mold.
