Description

Изобретение относится к области цветной металлургии и касается составов литейных сплавов на основе цинка, которые могут быть использованы в машиностроении, приборостроении.The invention relates to the field of non-ferrous metallurgy and relates to compositions of cast alloys based on zinc, which can be used in mechanical engineering, instrument making.

Известен сплав на основе цинка, содержащий, мас.%: алюминий 13,0-21,0; медь 1,7-3,7; железо 0,05-0,5; магний 0,01-0,07; кремний 0,8-2,4; бор 0,01-0,03; цинк - остальное [1].A known alloy based on zinc, containing, wt.%: Aluminum 13,0-21,0; copper 1.7-3.7; iron 0.05-0.5; magnesium 0.01-0.07; silicon 0.8-2.4; boron 0.01-0.03; zinc - the rest [1].

Задача изобретения состоит в снижении линейной усадки сплава.The objective of the invention is to reduce the linear shrinkage of the alloy.

Технический результат достигается тем, что сплав на основе цинка, содержащий алюминий, кремний, бор, дополнительно включает кадмий, причем компоненты находятся при следующем соотношении, мас.%: алюминий 8,0-10,0; кремний 0,4-0,6; бор 0,01-0,03; кадмий 1,0-3,0; цинк - остальное.The technical result is achieved in that the zinc-based alloy containing aluminum, silicon, boron, additionally includes cadmium, and the components are in the following ratio, wt.%: Aluminum 8.0-10.0; silicon 0.4-0.6; boron 0.01-0.03; cadmium 1.0-3.0; zinc is the rest.

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

Кремний снижает температуру плавления сплава, его линейную усадку. Бор и кадмий повышают жидкотекучесть сплава. Алюминий повышает прочность и вязкость сплава. Линейная усадка сплава составит не более 0,75%.Silicon reduces the melting point of the alloy, its linear shrinkage. Boron and cadmium increase the fluidity of the alloy. Aluminum increases the strength and toughness of the alloy. The linear shrinkage of the alloy will be no more than 0.75%.
