PWA-S-5663 - Pratt & Whitney Nickel 718 Heat Treated & Aged Specification
PWA-S-5663 is defined by Pratt & Whitney as Aerospace Material Specification for 718 (Ni-Co-Cr) Alloy, also known as Inconel 718, heat treated and aged, with specifications equivalent to those described by specification 5663. It defines specifications relating to mechanical, thermal, and metallurgical properties required by various jet engine parts.
Overview of PWA-S-5663
Nickel 718, as specified under PWA-S-5663, is fully solution heat treated and precipitation hardened when maximum strength and temperature properties are desired.
It ensures consistent properties across all approved sources by controlling:
- Heat treatment cycles and cooling rates
- Hardness and grain structure
- Chemical and mechanical conformance
- Non-destructive testing and certification
