Monel is a collection of nickel alloys , basically consists of nickel ( up to 67% ) and also copper , with minimal amounts of iron , manganese , carbon , and also silicon . Stronger compared to pure nickel, Monel alloys are resistance against corrosion by many agents, such as quickly flowing seawater. They could be constructed easily by hot- or cold-working, machining, and also welding.
Monel 400 is binary metal of the similar quantities of nickel and also copper as exists normally in the nickel ore from the mines which is so regarded a puritan alloy. It will be a very costly alloy, with expense which range from 5 to 10 times the price of copper and nickel; thus its use is restricted to those applications where it cannot be replaced with less expensive alternatives. When compared with carbon steel, piping in Monel is much more than three times as expensive.
