Alloy L605 Nickel Bar

Exceptional strength.


Alloy L605 represents one of the strongest fabricable cobalt alloys currently available.

Our Alloy L605 bars combines cobalt, nickel, chromium and tungsten for exceptional strength.


Alloy L605 is a cobalt-nickel-chromium-tungsten alloy with exceptional strength and good oxidation resistance in environments up to 1093°C (2000°F) for prolonged exposures. The alloy offers good fabricability, forming welding and machining. L605 is known under various common trade names, including Udimet alloy L-605, Haynes 25 and ATI L605. Our product provides good resistance to wear and galling and is ideal for applications that require good strength with oxidation resistance at elevated temperatures.


Attractive Performance

Alloy L605 represents one of the strongest fabricable cobalt alloys currently available. The attractive performance characteristics of the alloy make it highly suitable for applications including aircraft engines, gas turbines and ball bearings.
