TC1 titanium bar aerospace grade
TC1 titanium aerosapce grade chemical composition is Ti2Al1.5Mn. It is most suitable for the manufacture of parts with complex shape stamping and welding, and has been widely used in the aerospace industry and civil industry.
Product Introduction
TC1 is a low-alloy α-type titanium alloy (Ti-2Al-1.5Mn) designed for applications requiring a balance of strength, formability, weldability, and thermal stability.
Aluminum (Al ~2%) acts as an α-phase stabilizer, providing solid solution strengthening
Manganese (Mn ~1.5%) acts as a β stabilizer, improving plasticity and workability
The alloy is classified as a near-α titanium alloy with excellent processing performance and slightly higher strength than commercially pure titanium.
Key Characteristics
Slightly higher strength than industrial pure titanium
Excellent hot and cold processing plasticity
Good weldability
Stable performance at elevated temperatures
Long-term service capability up to 350°C
Thermal Performance
Recommended Working Temperature: ≤ 350°C
Service Life:
350°C → up to 2,000 hours
