Description
🧪 Advanced Ti-6246 Titanium Plate – Superior TC19 Ti-6Al-2Sn-4Zr-6Mo Sheet
📌 Product Overview
The Ti-6246 titanium plate (also referred to as TC19 titanium plate or Ti-6Al-2Sn-4Zr-6Mo sheet) is a high-performance, aerospace-grade alloy engineered for demanding environments. With excellent heat resistance, fatigue strength, and long-term structural reliability, it is ideal for aerospace, defense, marine, and high-temperature industrial applications.
What sets Ti-6246 titanium plate apart from other titanium alloys is its unique balance of properties, particularly its ability to maintain strength and structural integrity at elevated temperatures exceeding 500°C. Unlike Ti-6Al-4V, which softens significantly beyond 400°C, the Ti-6246 alloy remains dependable in turbine engines, high-speed rotating assemblies, and pressure-resistant enclosures.
🧪 Chemical Composition
| Element | Composition (%) |
|---|---|
| Titanium (Ti) | Balance |
| Aluminum (Al) | 5.5 – 6.5 |
| Tin (Sn) | 1.8 – 2.2 |
| Zirconium (Zr) | 3.6 – 4.4 |
| Molybdenum (Mo) | 5.5 – 6.5 |
| Oxygen (O) | ≤ 0.15 |
| Iron (Fe) | ≤ 0.25 |
| Carbon (C) | ≤ 0.05 |
| Hydrogen (H) | ≤ 0.015 |
| Nitrogen (N) | ≤ 0.03 |
This carefully balanced chemistry offers a unique microstructure that combines high tensile strength, toughness, and oxidation resistance—essential for aerospace-grade titanium sheet and plate components.
🏋️ Mechanical Properties
In both annealed and solution-treated + aged (STA) conditions, Ti-6246 titanium plates demonstrate remarkable performance:
- Tensile Strength: 1100–1300 MPa
- Yield Strength: ≥1000 MPa
- Elongation: ≥8%
- Reduction of Area: ≥25%
- Fatigue Resistance: Excellent (superior to Ti-6Al-4V)
- Operating Temperature: Up to 550°C
The alloy also exhibits creep resistance under stress at elevated temperatures, making it ideal for aerospace structural assemblies and engine mounting components. In addition, the low oxygen and iron content improves its ductility and weldability—traits essential for custom titanium fabrications.

🌟 Key Advantages
🔹 High Specific Strength: Significantly higher than commercially pure titanium, comparable to beta titanium alloys but with better stability.
🔹 Heat Resistance: Up to 550°C without loss of structural integrity, outperforming most near-alpha and alpha-beta alloys.
🔹 Superior Fatigue Life: Ideal for load-bearing, vibration-intensive systems.
🔹 Excellent Corrosion Resistance: Particularly in oxidizing and marine environments.
🔹 Stable in Thermal Cycling: No embrittlement or phase change degradation.
🔹 Customizable Heat Treatment Options: Annealed, beta-quenched, and aged.
These advantages make TC19 titanium alloy plate the material of choice in jet turbine hardware, afterburner components, and exhaust ducting.
