Abstract:
A cold drawing process for forming titanium blanks into titanium pieces in which the titanium blank is pre-treated with a wet lubricant prior to drawing. The wet lubricant lubricates the interfaces of the titanium blank and the punch to substantially reduce galling and hardening of the surface of the titanium blank from the drawing process, thereby eliminating the need to anneal the formed titanium pieces prior to additional drawing, stamping, punching or other forming processes.
