This Cobalt-Chromium-Nickel alloy gives a combination of
high strength, ductility and good mechanical properties and
is age hardenable. Phynox also has excellent fatigue life,
corrosion resistance in numerous environments and is
non-magnetic.
Use where a high resistance to corrosion and / or low relaxation at temperatures up to 380oC (715oF) are required.
Applications include:
- Springs
- Seal Components
- Medical Devices
- Components for Watches
- Aerospace Applications
- Petro-chemical Applications
- Marine Engineering
