Titanium Ti-6Al-4V
Titanium Ti-6Al-4V (Grade 5) – The Premier Aerospace and Medical Titanium Alloy
Titanium Ti-6Al-4V (Grade 5) is the most widely used titanium alloy in the world, accounting for over 50% of total titanium production. Its alpha-beta microstructure delivers an outstanding combination of high strength (950 MPa tensile), low density (4.43 g/cm³), excellent corrosion resistance, and biocompatibility unmatched by any other structural metal.
Key Properties
- Tensile Strength: 950 MPa
- Yield Strength: 880 MPa
- Density: 4.43 g/cm³ — 57% of steel s weight
- Fatigue Strength: 510 MPa
- Corrosion Resistance: Good (excellent in seawater)
- Standards: AMS 4928 / ASTM B265 Grade 5
Common Applications
Aerospace airframes and engine components, orthopedic implants (hip and knee replacements), dental implants, motorsport components, marine fasteners, and high-performance sporting goods.
