Description
⭐ Grade 6 Titanium Rod – Technical Specification & Industrial Performance Report
The Grade 6 Titanium Rod, engineered from the Ti-5Al-2.5Sn alloy system, is a near-alpha titanium material specifically optimized for service environments requiring long-term thermal stability, high creep resistance, and predictable mechanical performance under elevated temperatures. As one of the most stable and thermally reliable titanium alloys in industrial and aerospace use, the Grade 6 Titanium Rod demonstrates exceptional oxidation resistance, excellent weldability, and strong structural integrity in applications where conventional titanium alloys cannot maintain performance consistency.
The chemistry of Ti-5Al-2.5Sn is precision-designed to stabilize the alpha phase while enhancing creep resistance through the addition of tin. This metallurgical structure gives the Grade 6 Titanium Rod considerable advantages in aerospace, energy, marine, chemical, and industrial sectors that demand predictable high-temperature behavior and long-term dimensional accuracy.
🔧 Material Composition & Metallurgical Foundations
Near-Alpha Alloy System
Ti-5Al-2.5Sn belongs to the near-alpha titanium family, characterized by excellent creep resistance, superior oxidation stability, and predictable strength retention at high temperatures. Aluminum stabilizes the alpha phase, while tin enhances thermal creep resistance without compromising weldability.
📘 Chemical Composition of Ti-5Al-2.5Sn (Grade 6)
| Element | Typical Range (wt%) |
|---|---|
| Aluminum (Al) | 5.0 |
| Tin (Sn) | 2.5 |
| Oxygen (O) | ≤ 0.15 |
| Iron (Fe) | ≤ 0.25 |
| Nitrogen (N) | ≤ 0.05 |
| Carbon (C) | ≤ 0.08 |
| Hydrogen (H) | ≤ 0.015 |
| Titanium (Ti) | Balance |
This composition yields a strong, heat-resistant alpha matrix and uniform microstructural stability during long-term exposure to 300–480°C. Components manufactured from the Grade 6 Titanium Rod show excellent resistance to microstructural drift and dimensional distortion, even under cyclical thermal stress.
⚙️ Mechanical Properties (Aligned with AMS 4930 / MIL-T-9047)
The following performance values represent typical properties for annealed bar/rod:
| Property | Value |
|---|---|
| Density | 4.42 g/cm³ |
| Tensile Strength | 620 MPa typical |
| Yield Strength (0.2% offset) | 483 MPa typical |
| Elongation | 15% typical |
| Reduction of Area | ~30% |
| Modulus of Elasticity | 110 GPa |
| Hardness | 170–210 HB (correct value) |
| Service Temperature | Long-term up to 480°C |
These parameters reflect real AMS specifications and ensure that the Grade 6 Titanium Rod delivers consistent performance in high-temperature structural applications.
🛠️ Manufacturing Features & Processing Behavior
✔ Superior Weldability
One of the defining advantages of the Grade 6 Titanium Rod over many alpha-beta alloys is its outstanding weldability. The alloy accepts GTAW/TIG welding without significant risk of cracking, grain coarsening, or HAZ embrittlement, making it suitable for complex aerospace assembly and on-site repairs.
✔ Machining Behavior
Ti-5Al-2.5Sn machines more easily than Ti-6Al-4V and other high-strength titanium alloys. Carbide tooling, flood coolant, and controlled feed rates ensure predictable chip formation and surface finish.
✔ Formability
The material supports both cold-work and hot-work processes. Hot forming at 480–600°C enhances ductility while maintaining dimensional accuracy.
✔ Thermal Stability
The alloy’s near-alpha structure ensures high resistance to creep deformation, making the Grade 6 Titanium Rod ideal for continuous high-temperature loading.
