Description
✈ TC11 Titanium Bar – High-Strength Alloy for Aerospace & High-Temp Applications
The TC11 Titanium Bar is a premium-grade alpha-beta titanium alloy developed in China, comparable to international grades like Ti-6.5Al-3.5Mo-1.5Zr-0.3Si. With its excellent high-temperature strength, corrosion resistance, and weldability, TC11 is one of the most widely used titanium alloys in demanding industries such as aerospace, marine engineering, and industrial equipment manufacturing.
Conforming to Chinese national standards such as GB/T 3620.1, TC11 is specifically engineered for components exposed to high thermal and mechanical stresses.
🔍 Key Features of TC11 Titanium Bar
✅ Excellent High-Temperature Strength
TC11 maintains mechanical performance up to 500–550°C, making it ideal for turbine blades, engine parts, and high-temp structural brackets.
✅ Outstanding Weldability
Unlike other alpha-beta alloys (e.g., Ti-6Al-4V), TC11 titanium bar offers superior weldability with fewer heat-affected zone defects, making it preferred for pressure vessels and complex assemblies.
✅ High Fatigue & Creep Resistance
It provides stable fatigue behavior under cyclic loads and resists creep deformation at elevated temperatures.
✅ Superior Corrosion Resistance
Performs well in oxidizing environments, seawater, and acidic gases, suitable for marine and chemical industries.
✅ Reliable Machinability & Forging Properties
TC11 bars are suitable for hot forging, CNC machining, and turning, and retain dimensional stability after treatment.

📊 Mechanical Properties (Annealed Condition)
| Property | Typical Value |
|---|---|
| Tensile Strength | 950–1100 MPa |
| Yield Strength | 850–950 MPa |
| Elongation | 10–15% |
| Reduction of Area | 25–35% |
| Hardness | ~32 HRC |
| Density | 4.5 g/cm³ |
| Operating Temp | ≤ 550°C (continuous) |
TC11 titanium bar maintains strength and ductility under elevated thermal loads and is therefore trusted in aeroengine hot section components and airframe load-bearing parts.
