It is impossible to create alloy of copper with tungsten by classical method of metal alloying due to huge retail in their technological parameters. Melting point of tungsten is 3380 °C, while copper boils at t° 2567 °C. Alloy has high heat resistance, wear resistance, resistance to high loads and excellent electrical conductivity.
Invention relates to powder metallurgy. Tungsten powder is mixed with rosin 0.5−1.5; % or ammonium citrate 0.05−0.15%. Mixture is pressed, resulting porous preform is brought into contact with copper. Carry out heat treatment with gradual increase in temperature, first in vacuum until binder is removed and copper is melted, and then in argon to 1360−1410 °C. Technical result is to increase the wettability, uniformity of impregnation. Disadvantage of these methods is need for additional application of pressure during sintering, which increases cost of product.
