Product Introduction
TC11 is an α-β type heat-resistant titanium alloy with a nominal composition of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si. It offers an excellent balance of strength, heat resistance, and corrosion resistance, making it suitable for high-temperature and high-stress environments such as aerospace, marine, and chemical processing.
Among commercially pure titanium grades (Gr1–Gr4), this alloy is stronger and more corrosion-resistant than lower grades and performs better than Grade 5 (Ti-6Al-4V) in oxidizing and chloride-rich media, though it has slightly reduced formability.
It remains nearly 99 % pure titanium, with added elements providing improved heat resistance, strength, and low-temperature impact toughness. The alloy also exhibits good forgeability, weldability, and machinability.
