Monel...

I was surveying a Stephens 36 last week that had Monel fuel tanks...it's an alloy which was very popular at one time but now days - no one hardly no what it is...never the less it's a great marine metal but very exoensive...Monel is a nickel-copper alloy, first developed in 1905, containing about 66 percent nickel and 31.5 percent 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. Monel is a registered trademark of the International Nickel Company.
