Description

Изобретение относится к области цветной металлургии и касается составов сплавов на основе меди, которые могут быть использованы для изготовления монет, бижутерии.The invention relates to the field of non-ferrous metallurgy and relates to compositions of alloys based on copper, which can be used for the manufacture of coins, jewelry.

Известен сплав на основе меди, содержащий, мас.%: алюминий 6,0-8,0; медь - остальное [1].Known copper-based alloy containing, wt.%: Aluminum 6.0-8.0; copper - the rest [1].

Задачей изобретения является повышение прочности сплава.The objective of the invention is to increase the strength of the alloy.

Технический результат достигается тем, что сплав на основе меди, содержащий алюминий, дополнительно содержит галлий, марганец и серебро при следующем соотношении компонентов, мас. : алюминий 6,0-8,0; галлий 1,0-1,5; марганец 1,0-1,5; серебро 6,0-8,0; медь - остальное.The technical result is achieved in that the copper-based alloy containing aluminum additionally contains gallium, manganese and silver in the following ratio of components, wt. : aluminum 6.0-8.0; gallium 1.0-1.5; manganese 1.0-1.5; silver 6.0-8.0; copper is the rest.

В таблице приведены составы сплава на основе меди.The table shows the composition of the alloy based on copper.

Алюминий снижает плотность сплава. Марганец и серебро повышают механические свойства сплава. Галлий препятствует окислению сплава на основе меди. Выплавка сплава может быть проведена в тигельных и шахтных индукционных печах, футерованных шамотом.Aluminum reduces the density of the alloy. Manganese and silver enhance the mechanical properties of the alloy. Gallium inhibits the oxidation of copper-based alloys. Smelting of the alloy can be carried out in crucible and shaft induction furnaces lined with chamotte.
