Applications
- Jet engine compressor blades, discs and rings
- Airframe components
- Military hardware
- Pressure vessels
- Space craft components, including rocket engine
- Medical & surgical devices. A variant 6Al-4V ELI (Extra Low Interstitial) is often used for these applications

Additional Information
Weldability
This alloy can be welded by using inert gas shielding. Spot, seam, flash and pressure welding are also used depending on application.
Charcteristics
- High strength to weight ratio
- Good corrosion resistance
- Good elevated temperature strength
- Good low temperature impact strength
- Good creep resistance
Machinability
Machining is similar to that of austenitic stainless steels, e.g. 304, 316. Slow speeds, heavy feeds, and non-chlorinated cutting fluids are typically used for most applications.
