Overview of TC11 (Ti-6.5Al-3.5Mo-1.5Zr-0.3Si) Titanium Alloy Welding Wire
TC11 is a heat-resistant alpha-beta titanium alloy welding wire, with its closest international equivalent being Ti-6-2-4-2. It provides excellent creep resistance and high-temperature stability, maintaining high strength at service temperatures up to 500°C. With its superior thermal properties, TC11 is primarily used in the hot sections of aero-engine components such as compressor disks and blades.
