Industrial Applications: Gas turbine components, biomedical implants (like artificial joints, bone plates), marine engineering equipment, and high-performance automotive parts.

Other Fields: Chemical processing equipment, sporting goods, and other high-strength, lightweight, and corrosion-resistant applications.

The alloy complies with a range of international and industry standards, including but not limited to:

ASTM: B265, B348, B381

AMS: 4911, 4928, 4965, 4967

ISO: 5832-3

MIL-T: 9046, 9047

Aluminum (Al): 5.5 - 6.75

Vanadium (V): 3.5 - 4.5

Carbon (C): ≤ 0.08

Iron (Fe): ≤ 0.40

Oxygen (O): ≤ 0.20

Nitrogen (N): ≤ 0.05

Hydrogen (H): ≤ 0.015

Other Elements (each): ≤ 0.10

Other Elements (total): ≤ 0.40

Titanium (Ti): Balance

Tensile Strength: ≥ 895 MPa (≥ 130 ksi)

Yield Strength (0.2% Offset): ≥ 825 MPa (≥ 120 ksi)

Elongation: ≥ 10%

Reduction of Area: ≥ 20%

Modulus of Elasticity: ~ 114 GPa (~16.5 x 10^6 psi)

Hardness (Brinell): ~ 334 HB

Density: 4.43 g/cm³ (0.160 lb/in³)

Melting Range: 1604 - 1660 °C (2919 - 3020 °F)

Heat Treatment: It can be strengthened through solution treatment and aging.

Hot Working: Forging, rolling, and other hot working should be performed within the appropriate temperature range. Common forging temperatures are between 925°C - 955°C (1700°F - 1750°F). Care must be taken to control the cooling rate to prevent embrittlement.

Cold Working: It has moderate cold working formability but is more difficult than commercially pure titanium. Intermediate annealing is often required.

Annealing: Stress relief annealing is typically performed at 480°C - 650°C (900°F - 1200°F). Mill annealing is commonly done at 700°C - 800°C (1300°F - 1475°F). The specific process depends on the section size and desired properties.

Aging: Aging treatment is conducted at 480°C - 595°C (900°F - 1105°F) for 2 to 8 hours.

Machinability: Similar to austenitic stainless steel. It requires the use of sharp tools, low cutting speeds, high feed rates, ample cooling, and rigid workpiece support.
