Titanium Seamless Tubing Grade 9
Grade 9 seamless titanium tubing - Ti-3Al-2.5V near-alpha alloy: yield >=483 MPa (annealed), density 4.48 g/cm3, excellent weldability - for aerospace hydraulic, marine and chemical service.
Description
What Grade 9 Is
Grade 9 titanium - Ti-3Al-2.5V - is a near-alpha titanium alloy (corrected from the original text's 'alpha-beta' classification) with about 3% aluminum and 2.5% vanadium. The small alloying addition roughly doubles the annealed strength of commercially pure titanium while preserving excellent weldability and formability - the reason Grade 9 is standard for aerospace hydraulic and ducting tube.
Chemical Composition (wt %)
| Ti | Al | V | Fe | C | N | H | Others each |
|---|---|---|---|---|---|---|---|
| 92.6-95.5 | 2.5-3.5 | 2.0-3.0 | <=0.25 | <=0.08 | <=0.030 | <=0.015 | <=0.10 |
Mechanical Properties (Annealed, Per ASTM B861)
| Property | Value |
|---|---|
| Tensile strength | >=620 MPa (annealed; 862 MPa corresponds to high-strength/cold-worked conditions - always state the condition) |
| Yield strength | >=483 MPa |
| Elongation at break | >=10% |
| Modulus of elasticity | 105-120 GPa |
| Shear modulus | 43-45 GPa |
| Poisson's ratio | 0.30 |
Professional titanium material supplier - GNEE
Physical Properties
Density: 4.48 g/cm3.
Melting range: approximately 1670-1700°C (alloy-system values, approx).
Key Features
Strength and toughness under elevated temperature and pressure - aerospace and aeroengine applications.
Corrosion resistance in seawater and salt water - marine engineering and chemical equipment.
Excellent weldability - conventional, arc and laser welding; highly plastic and machinable in manufacture.
Low density for lightweight design.
Applications
Aerospace hydraulic tubing and ducting (the classic Grade 9 role).
Aircraft structural components and fasteners.
Marine engineering components and chemical equipment piping.
Automotive and sports equipment where light weight and moderate-high strength are needed.
Selection Note
Grade 9 is the best weldability-to-strength compromise between the CP grades and Grade 5. For very high strength, move to Grade 5 (Ti-6Al-4V) or Grade 23 (ELI). Always confirm the delivery condition (annealed vs cold-worked) when comparing mechanical data.
