Definitions

  • a hydrostatic extrusion process for producing relatively fine gauge wires less than 250a in diameter by liquid pressure extruding a metal ingot of larger diameter than that of a die opening, through said die opening of a high pressure container, the improvement wherein a liquid providing a viscosity less than lOO poise at a pressure of l0,000 atmospheric is employed as the pressure medium contained in the high pressure container.
