Printable PDFMonel® alloy K-500
W.Nr 2.4375
Applications
Springs, pumps, valves, and fasteners.
Description
Monel® 500 is an age-hardenable Nickel-Copper alloy with Aluminum and Titanium added to the base. The addition of Aluminum and Titanium provides high strength and hardness. Monel® 500 remains ductile, tough, and is nonmagnetic even at lower temperatures. Monel® 500 is corrosion resistant and can operate from cryogenic temperatures to 450°F (232°C).
Industries Supplied
Oil & Gas Extraction, Marine, Chemical Processing, and Medical.
