Applications
1. Aerospace Industry
Titanium Grade 5 is the primary alloy used in aircraft structures
and engine components due to its high strength-to-weight ratio, heat resistance, and oxidation resistance.
Applications include:
Jet engine compressor blades and discs
Aircraft skins and structural panels
Fasteners and landing gear components
2. Medical and Healthcare
With excellent biocompatibility, Titanium Gr5 is widely used in:
Orthopedic implants and prosthetics
Dental implants
Surgical instruments
3. Marine and Offshore Engineering
Titanium’s seawater corrosion resistance makes it ideal for:
Submarine hulls and propeller shafts
Offshore oil platform components
Seawater piping and heat exchangers
4. Automotive and Motorsport
Used in high-performance vehicles to reduce weight and increase
durability:
Engine valves and connecting rods
Exhaust systems
Suspension components
