Ti-6AL-4V alloy is the most widely used titanium alloy of the alloy of the alpha-lus-beta class, and is also the most common of all titanium alloys. This modification incorporates extra low interstitials (ELI) and also has a ruthenium addition to enhance the corosion properties. The wrought material is used in applications where moderate strength, good strength to weight, and favorable corrosion properties are required. The alloy is available as wire, sheet, bar, plate, forgings, billet and rings.
Based on this material, the product form including:
- Sheet, Streip, and Plate (ASTM B265);
- Bar and Billet, Annealed (ASTM B348);
- Seamless and Welded Fittings (ASTM B363);
- Forgings (ASTM B381);
- Seamless Pipe (ASTM B861);
- Welded Pipe (ASTM B862);
- Wire (ASTM B863);
- Weld Wire (AWS A5.16 ERTi-29).
