Titanium Grade 1 is   "unalloyed" titanium offering optimum ductility and
  cold formability. This grade has high impact toughness and is readily weldable.
  The material is capable of deep drawing, and used for plate, frame, and tube
  heat exchangers, and also is used as plate for explosive bonding for clad   plate.
  The titanium grade is castable and is sometimes utilized "as   cast" in dental
  applications. The alloy is available as casting, wire, welded tube, bar,   plate,
  sheet, forgings, and billet.
