Monel, << moh NEHL, >> metal is an important alloy of nickel and copper. It contains about 67 per cent nickel and 30 per cent copper. The rest is made up of such elements as aluminum, iron, manganese, or titanium. Monel metal looks like nickel. It is about as hard as steel and can be forged and drawn into wire or other shapes. It is easier to prepare than nickel, for some ores already contain nickel and copper in suitable proportions. Thus, the alloy is sometimes cheaper than pure nickel.
Monel metal generally resists corrosion, showing hardly any damage from steam, seawater, hot gas, air, or acids. This property makes it useful in sheet-metal work, in chemical plants, and on ships. It is used for pump fittings, propellers, and condenser tubes; as a covering for sinks and soda fountains; and for containing and transporting acids.
