TC21 is a high-strength and damage-tolerance alpha-beta titanium alloy. Its nominal composition is Ti-6Al-2Sn-2Zr-3Mo-1Cr-2Nb with silicon as a minor alloying element. It is designed for applications requiring a combination of strength, fracture toughness and damage tolerance.
TC17 is a high-strength alpha-beta titanium alloy with nominal composition Ti-5Al-2Sn-2Zr-4Mo-4Cr. Its microstructure and heat-treatment response allow it to achieve a high strength level while maintaining useful ductility, making it suitable for demanding aerospace structural and engine applications.
TC11 is a heat-resistant alpha-beta titanium alloy with nominal composition Ti-6.5Al-3.5Mo-1.5Zr-0.3Si. It offers good high-temperature strength and hot-working performance and is widely associated with compressor components such as blades, discs, drums and shafts.
TC6 is an alpha-beta titanium alloy with a combination of strength, thermal performance and hot-workability. Its nominal composition is Ti-6Al-2.5Mo-1.5Cr-0.5Fe-0.3Si, and it is used particularly for high-strength aerospace engine components.
TC4 is the Chinese designation for Ti-6Al-4V and corresponds to ASTM Grade 5. It is one of the most widely used alpha-beta titanium alloys, offering high specific strength, good corrosion resistance, good fatigue performance and versatile processing characteristics.
TC1 is a low-alloy alpha-beta titanium alloy based on the Ti-Al-Mn system. It provides a combination of moderate strength, good formability, weldability and corrosion resistance and can be processed into plates, sheets and other semi-finished products.
