Description

Изобретение относится к области металлургии и касается составов сплавов на основе меди, которые могут быть использованы для изготовления монет.The invention relates to the field of metallurgy and relates to compositions of copper-based alloys that can be used to make coins.

Известен сплав на основе меди (латунь), содержащий, мас.%: никель 5,0-26,0; цинк 12,0-49,0; кремний 0,3-0,4; сера 0,01-0,25; серебро 0,01-0,25; бор 0,01-0,25; медь 45,0-72,0 [1].Known alloy based on copper (brass), containing, wt.%: Nickel 5.0-26.0; zinc 12.0-49.0; silicon 0.3-0.4; sulfur 0.01-0.25; silver 0.01-0.25; boron 0.01-0.25; copper 45.0-72.0 [1].

Задачей изобретения является упрощение технологии получения сплава на основе меди.The objective of the invention is to simplify the technology for producing an alloy based on copper.

Технический результат достигается тем, что сплав на основе меди, содержащий никель и серебро, дополнительно включает галлий, причем компоненты находятся при следующем соотношении, мас.%: никель 10,0-15,0; серебро 10,0-15,0; галлий 3,0-5,0; медь 65,0-77,0.The technical result is achieved in that the copper-based alloy containing nickel and silver further includes gallium, the components being in the following ratio, wt.%: Nickel 10.0-15.0; silver 10.0-15.0; gallium 3.0-5.0; copper 65.0-77.0.

В таблице приведены составы сплава.The table shows the alloy compositions.

В составе сплава компоненты проявляют себя следующим образом. Серебро и никель повышает прочность сплава. Галлий обеспечивает пластичность.In the composition of the alloy, the components manifest themselves as follows. Silver and nickel increase the strength of the alloy. Gallium provides plasticity.

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.
