TUNGSTEN-COPPER ALLOY HAVING UNIFORM STRUCTURE, AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a tungsten-copper alloy having a uniform structure by using a powdery mixture of tungsten powder and tungsten-copper composite powder instead of a powdery mixture of tungsten powder and copper powder. SOLUTION: A stage where tungsten powder and tungsten-copper composite powder are mixed to form a powdery mixture; a stage where the powdery mixture is compacted to form a compact; a stage where the compact is sintered to form a skeleton; and a stage where copper is contacted with the skeleton and is infiltrated therein are performed, so that the tungsten-copper alloy having a uniform structure is produced.
