    Introduction:


     This Cobalt-Chromium-Nickel alloy also known as Elgiloy 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. This alloy is recommended where a high resistance to corrosion and / or low relaxation at temperatures up to 380°C are required.
