Nickel Alloy L-605, which is also sold under the brand names Cobalt® L-605 and Haynes® 25, is a solid-solution, cobalt-nickel-chromium-tungsten alloy. Nickel Alloy L-605 is known for a number of unique properties including:

• High-temperature strength
• Good resistance to prolonged exposure to oxidizing environments up to 1800°F (980°C)
• Excellent resistance to sulfidation
• Great ductility, plus good forming and welding characteristics
• Resistance to wear and galling

Because of these and many other outstanding properties Nickel Alloy L-605, Cobalt L-605, and Haynes 25 are popular in a number of different industries for a wide range of applications.  The aerospace and marine industries rely on Nickel Alloy L-605 for:

• Gas Turbine applications (rings, blades, and combustion chamber parts
• Industrial furnace applications
• Muffles and liners in high-temperature kilns

In order to be called Nickel Alloy L-605, Cobalt L-605 and Haynes 25, an alloy must have a specific chemical composition which includes:

• Cr 19-21%
