Titanium Grade 5 (Ti-6Al-4V) Foil for Aerospace & Aviation Applications
High-Performance Titanium Foil for Aircraft and Engine Systems
Titanium Grade 5 (Ti-6Al-4V) foil is a critical aerospace material widely used by Boeing, Airbus, and leading aircraft engine manufacturers. With its exceptional strength-to-weight ratio, outstanding fatigue resistance, corrosion resistance, and thermal stability, GR5 titanium foil supports modern aircraft designs that demand lightweight structures, long service life, and high reliability.
As aircraft platforms increasingly rely on advanced composites, high-temperature engine environments, and precision assembly, Titanium GR5 foil has become an essential solution across airframe, engine, and space systems.
Aerospace Applications of Titanium Grade 5 Foil
Composite Airframe Structures (Boeing & Airbus Programs)
Titanium GR5 foil is extensively used in composite-intensive aircraft platforms such as the Boeing 787, 777X, Airbus A350, and A220.
Typical uses include:
- Corrosion-resistant barrier layers between CFRP and aluminum
- Bonded interface foils in composite-to-metal joints
- Laminated layers in lightweight structural panels
Key benefits for OEMs:
- Prevents galvanic corrosion
- Excellent fatigue resistance for high flight cycles
- Thermal expansion compatibility with composite materials
Precision Shims and Spacers for Aircraft Assembly
Titanium Grade 5 foil is widely specified for aerospace shims and spacers requiring tight tolerances and long-term stability.
Applications:
- Wing-to-fuselage joints
- Engine pylons and mounts
- Landing gear and structural assemblies
Why aerospace OEMs choose GR5 foil:
- High compressive strength in thin gauges
- Dimensional stability under vibration and load
- Corrosion resistance throughout aircraft service life
Engine Nacelles and Thermal Protection Systems
