Title: Brittle wire manufacturing method and apparatus

Abstract: A method for making wire of brittle alloys including coating rods of the brittle alloy with refractory fluoride and organic polymer, loading the coated rods into a container, filling the container with metallic powder, sealing the container, heating the filled and sealed container, extruding the filled container into a diminished diameter and elongated length bar filled with reduced diameter wires, removing the container from the wires, and separating the wires. Alternatively continuously passing brittle alloy wire through a clamshell furnace, a liquid gas quench, roll reduction process, cleaning and polishing process, and final storage process.
