Manufacturing Process of TC4 Titanium Bar for Aviation

Melting: three vacuum arc melting (VAR) to ensure low impurities.
Thermomechanical processing:
Forging: β phase forging (1050℃±10℃), forging ratio＞6, grain refinement to ASTM 8-10 grade.
Rolling: hot rolling, cold rolling, size range Φ5-200 mm, wall thickness 0.5-25 mm.
Heat treatment: 650℃ vacuum annealing to optimize grain size and residual stress.

Features of TC4 Titanium Bar For Aviation

High strength and light weight

Tensile strength can reach more than 900 MPa, density is only 4.43 g/cm³, specific strength (strength/density) is much higher than steel and aluminum alloy, which can significantly reduce the weight of aircraft structure.

Excellent corrosion resistance

Performs well in humid, salt spray, and acidic environments; no additional anti-corrosion coating is required, suitable for harsh environments (such as marine climates).

Stable high temperature performance

Long-term working temperature can reach 400°C (short-term 500°C), suitable for high-temperature components such as engines.

Good fatigue resistance and fracture toughness

Strong crack propagation resistance, suitable for aviation structural parts subjected to alternating loads.
