The invention relates to metallurgy, in particular the production of alloys of molybdenum, used for the manufacture of products having threaded connections and functioning at high temperatures, for example electrodes

FIELD: powder metallurgy.

SUBSTANCE: parts of devices protecting against radioactive emission or electric contacts are proposed to be manufactured from tungsten/copper pseudoalloy. Tungsten powder is mixed with binder containing 0.5-1.5% colophony and 0.05-0.15% ammonium formate or citrate. Resulting mixture is compacted and resulting porous blanc is brought into contact with copper. The total is thermally treated by gradually raising temperature: first in vacuum to remove binder and to melt copper and then in argon atmosphere to 1360-1410оС.

EFFECT: increased wettability and uniformity of impregnation, and eliminated explosive risk due to excluded use of hydrogen.
