Ti 6Al-4V (Grade 5)
Ti 6Al-4V, also known as Grade 5, is the most popular titanium alloy, ideal for parts that require high strength while remaining lightweight. It possesses high corrosion resistance and fair weldability and formability. Ti 6Al-4V is also heat treatable, unlike “pure” grades of titanium.
Ti 6Al-4V has a machining cost factor of 6.0 when compared to steel 12L14. It produces a fair weld and forges roughly. Ti 6Al-4V can also be annealed, heat treated, and aged.
Industries & Applications
- Rings
- Fasteners
- Aircraft parts
- Biomedical implants
- Aerospace components
