TA7 (ELI) GR6 Titanium Alloy

Overview of TA7 Titanium Alloy

  • TA7 Type: Medium strength α-type titanium alloy
  • Heat Treatment: Cannot be strengthened by heat treatment, usually used in the annealed state
  • Fracture Toughness: Good at both room temperature and high temperatures
  • Weldability: Excellent fusion welding performance, suitable for tungsten electrode and metal electrode fusion welding processes under inert gas protection
  • Applications:
    • Manufacturing of casing shells, wall panels, and other parts
    • Long-term working temperature up to 500°C
    • Short-term working temperature up to 800°C
    • TA7ELI alloy with low interstitial impurity elements is suitable for low-temperature applications
  • Semi-Finished Products:
    • Sheets, rods, billets, rings
    • Can also be used for casting production
