Monel® 400 Disk

Goodfellow's Monel® 400 Disk is a nickel-copper alloy foil known for its high strength, toughness, and resistance to corrosion and acids. With a nickel content around 63%, Monel® 400 demonstrates superior mechanical properties and durability compared to pure nickel, making it suitable for applications requiring frequent temperature changes or exposure to corrosive environments. Goodfellow offers Monel® 400 Disk in a range of thicknesses ideal for gaskets, fasteners, springs, valves and other parts where longevity and performance are critical.
