To create an alloy of copper-tungsten classic method of fusing metals is impossible because of the huge retail in their technological parameters. The melting point of tungsten is equal to 3380 °C, while copper boils at t° 2567 °C. the Alloy has high temperature resistance, abrasion resistance, resistance to high loads and excellent conductivity.
The invention relates to powder metallurgy. Mix the powder of tungsten with rosin 0.5 to 1.5;% or ammonium citrate 0,05−0,15%. The mixture is compressed, the resulting porous preform is brought into contact with copper. Carry out the heat treatment with a gradual rise of temperature first in a vacuum to remove the ligaments and melting the copper, and then in argon to 1360−1410°C. the Technical result is to increase the wettability, uniformity of impregnation. The disadvantage of these methods is the need for additional application of pressure during sintering, which increases the process of obtaining products.
Manufacture of electrical contacts, shielded from radiation.
