Phynox†

Available in any of the 'profile options'

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. This alloy is used in medical devices, dental products, surgical implants and orthopedics.
