TC 4 Titanium
TC4 is one of the most widely used titanium alloys today. It offers excellent overall performance, including high strength, good corrosion resistance, and relatively good workability. In the aerospace industry, it is used to manufacture aircraft structural components such as fuselage parts and landing gear. In the medical field, it is used to produce implants such as artificial joints and bone plates. For example, in the manufacturing of high-performance fighter aircraft fuselages, TC4 can ensure structural strength while reducing the overall weight of the aircraft, thereby improving flight performance.

Feature
TC4 is a widely used α+β titanium alloy renowned for its superior strength, toughness, and heat resistance, outclassing TC3 in high-demand scenarios. Its composition is precisely engineered: with titanium as the matrix, 5.5-6.75% aluminum strengthens the α phase and 3.5-4.5% vanadium stabilizes the β phase. Strict impurity limits (O: 0.20%, N: 0.05%, C: 0.08%, H: 0.015%, Fe: 0.30%) safeguard its integrity.
Mechanically, TC4 excels with 895 MPa tensile and 825 MPa yield strength, paired with 10-15% elongation. Stable up to 400°C, it offers enhanced fatigue and creep resistance, ideal for cyclic-loaded aerospace and industrial applications.
Corrosion-wise, its self-forming oxide layer resists atmospheric, fresh, and seawater exposure, outperforming TC3 in mild reducing acids. Fabrication is flexible: GTAW welding with post-heat treatment, machining with sharp tools and coolant, and heat treatment to precipitate α-phase for strength. These attributes make TC4 the go-to for aerospace, medical, marine, and industrial high-performance components.
