Composition of Grade 5 Titanium Bar
A Grade 5 titanium round bar consists of approximately 90% titanium, 6% aluminum, and 4% vanadium. The alloy is strengthened by a combination of alpha and beta phases, making it extremely durable. The addition of aluminum and vanadium enhances its strength and corrosion resistance.
Typical Chemical Composition (%)
| Grade | C (max) | N (max) | Fe (max) | Al (range) | O (max) | H (max) | Ti | V (range) |
|---|---|---|---|---|---|---|---|---|
| Gr 5 | 0.10 | 0.05 | 0.40 | 5.5-6.75 | 0.20 | 0.015 | Balance | 3.5-4.5 |
Physical Properties of Grade 5 Titanium Bar
The physical properties of ASTM B348 Gr5 titanium bars include density, melting point, and thermal conductivity.
Density: Approximately 4.43 g/cm³ (only about half the density of steel).
Melting Point: Approximately 1632°C (2970°F), which is higher than that of stainless steel.
Thermal Conductivity: Relatively low, at about 6.7 W/(m·K).
Mechanical Properties of Grade 5 Titanium Bar
The mechanical properties of Grade 5 titanium bars are impressive.
Tensile Strength: Up to 950 MPa (138,000 psi)
