Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding.
Characteristics of Monel:
• Good resistance to acids such as hydrofluoric and sulfuric acid
• Highly resistant to alkalis
• Malleable
• Highly corrosion resistant
• Stronger than steel
Applications of Monel:
• Pump shafts, oil-well tools, instruments, doctor blades and scrapers, springs, valve trim, fasteners, marine propeller shafts
• Marine components
• Chemical and hydrocarbon processing equipment
• Valves, pumps, shafts, fittings, heat exchangers
