Introduced an 1905 Monel was the pioneer of the nickel based alloys offering high strength and good corrosion resistance. Its toughness and good wear properties made it very popular with pump and valve manufacturers. Although over shadowed somewhat by the modern nickel iron chromium alloys and the high nickel chromium alloys, Monel is still an excellent choice where atmospheric corrosion is an issue, particularly sea water.

Monel is readily available as raw material in most shapes and sizes and, although tough, it is not that difficult to machine. Valves and fittings will cost about 4 times the price of a 316 stainless equivalent.
