Here are some key characteristics and properties of Titanium Grade 5:


  • Titanium (Ti): ~90%
  • Aluminum (Al): 6%
  • Vanadium (V): 4%

Key Properties

  1. High Strength: Ti-6Al-4V is known for its high strength-to-weight ratio, making it ideal for applications where strength is critical but weight needs to be minimized.
  2. Lightweight: Despite its strength, it is much lighter than steel and other high-strength materials.
  3. Corrosion Resistance: Excellent resistance to corrosion in various environments, including seawater and harsh industrial chemicals.
  4. Good Fabricability: It can be welded, machined, and formed relatively easily compared to other titanium alloys.
  5. Heat Resistance: Maintains its mechanical properties at temperatures up to around 400°C (752°F).


Due to its excellent properties, Titanium Grade 5 is widely used in various demanding applications, including:

  • Aerospace: Aircraft components, such as engine parts, airframes, and landing gear.
  • Medical: Surgical implants, prosthetics, and medical devices due to its biocompatibility.
  • Marine: Components in ships, submarines, and offshore structures.
  • Automotive: High-performance automotive parts and motorsport applications.
  • Industrial: Chemical processing plants, power generation, and other high-stress environments.

Mechanical Properties

  • Ultimate Tensile Strength: Approximately 950 MPa (138,000 psi)
  • Yield Strength: Approximately 880 MPa (128,000 psi)
  • Density: 4.43 g/cm³
  • Modulus of Elasticity: 114 GPa (16.5 million psi)

Titanium Grade 5 (Ti-6Al-4V) combines high strength, low weight, and excellent corrosion resistance, making it a versatile and valuable material across many high-performance industries.
