TC3 Titanium

TC3 is an α+β titanium alloy composed mainly of titanium, aluminum, zinc, and iron. It offers a balanced combination of high strength, low density, excellent corrosion resistance, high-temperature performance, biocompatibility, and good workability. Compared to steel and aluminum alloys, TC3 is significantly lighter and stronger. It is widely used in aerospace, marine, automotive, medical, chemical, and high-end sports equipment industries.

In aerospace, TC3 is used for compressor disks, engine impellers, structural components, and cryogenic fuel tanks (e.g., for rockets and missiles). In the medical field, it is applied to artificial joints, dental implants, and surgical tools due to its biocompatibility and corrosion resistance. In the chemical and marine industries, it is ideal for corrosive environments. In automotive and sports applications, TC3 is used for engine parts, chassis components, golf clubs, and bicycle frames, where high strength and light weight are critical.

TC3 is a medium-strength α+β titanium alloy with superior performance compared to TC2, boasting an optimal balance of strength, toughness, and processability for demanding structural applications. Its composition features 4.0-5.0% aluminum for α-phase strengthening and 0.8-1.5% vanadium for β-phase stabilization, enhancing heat resistance. Strict impurity limits (O≤0.20%, N≤0.05%, etc.) safeguard structural integrity.

With a tensile strength of 750-850 MPa and yield strength of 600-700 MPa, TC3 outperforms TC2 while maintaining 10-15% elongation. It excels at service temperatures up to 400°C and shows enhanced fatigue resistance, ideal for cyclic loading in moderate-heat environments.

TC3's protective oxide layer provides excellent corrosion resistance in atmospheres, fresh and seawater, performing well in marine and industrial settings. Though not suited for extreme reducing acids, it resists pitting and crevice corrosion.

Fabrication is achievable: GTAW with shielding enables welding, while post-weld heat treatment optimizes strength. Machining requires specialized tools due to higher strength, and α+β solution treatment with aging enhances performance. These attributes make TC3 perfect for aerospace structures, engine components, and high-stress marine hardware.
