Commercially pure Titanium and alpha alloys of titanium are non-heat treatable and are generally very weldable . They have:
• Low to medium strength
• Good notch toughness
• Reasonably good ductility
• Excellent mechanical properties at cryogenic temperatures
Pure titanium and alpha alloys possess the highest corrosion resistance.
More highly alloyed near-alpha alloys offer optimum high temperature creep strength and oxidation resistance.
