| General Information | |
| Titanium Alloy Grade 4 is “unalloyed” titanium offering improved strength, moderate ductility. The material is readily weldable. This material is very corrosion resistant in highly oxidizing and mildly reducing environments. The material is castable and is often utilized in cast valves and fittings. The alloy is available as castings, wire, plate, sheet, strip, forgings, bar, and billet. Used mostly in aerospace applications. | |
