GR9 titanium alloy possesses a range of advantages, including high specific strength, excellent corrosion resistance, low density, and good toughness and weldability. After solution strengthening, the strength of this titanium alloy increases, but the increase is not significant; its strength in the annealed state is generally around 900 MPa, while after treatment, the strength can reach 1100 MPa.
GR9 titanium alloy has been successfully applied in aerospace, petrochemical, shipbuilding, automotive, and pharmaceutical industries, thanks to its unique combination of properties. For example, in the aerospace field, the lightweight and high-strength characteristics of GR9 titanium alloy make it an ideal material for manufacturing aircraft and spacecraft components; in the petrochemical field, its excellent corrosion resistance enables it to withstand the erosion of various corrosive media.
Strength-Ductility Balance:
Tensile Strength: 620 MPa (annealed state) – Lower than Grade 23 but 30% stronger than pure titanium (Grade 1-4).
Elongation: ≥15% – Superior ductility vs. Grade 5 (≥10%), enabling complex forming and high fatigue resistance.
Density: 4.48 g/cm³ – 60% lighter than steel, ideal for weight-sensitive applications.
Corrosion Resistance:
Resists pitting/crevice corrosion in seawater, chlorides, and acidic/alkaline environments (e.g., HCl, H₂SO₄).
Outperforms stainless steel in marine/chemical processing, with no galvanic corrosion risk.
