PURPOSE: To obtain a titled alloy wire which is easy to work and has an excellent characteristic by ejecting a Cu-Cr alloy contg. a specific amt. of Cr through a fine hole or slit from a molten state into a liquid fluid and forming a slender long-sized casting ingot.

CONSTITUTION: A raw material 1 for a Cu-Cr alloy contg. 0.2W1.5% Cr is charged into a crucible 2 and is melted by a heater 4 in a nonoxidative atmosphere. The molten alloy is steadily ejected from the nozzle 5 in the bottom of the crucible 2 and is injected into liquid fluid 7 forming laminar flow on the inside of a rotary drum 6, by which the molten material is quickly solidified and a slender long-sized casting ingot 8 is obtd. The cooling rate is controlled in the stage of casting to eliminate segregation of Cr and to provide substantially the effect of soln. heat treatment thereto. The wire rod is subjected to annealing for the purpose of precipitation and tempering after cold drawing. The process for production is thus extremely simplified and the Cu-Cr alloy having the extremely excellent and uniform characteristic is obtd.
