Monel was created by Robert Crooks Stanley, who worked for the International Nickel Company (INCO) in 1901. Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore from the Sudbury (Ontario) mines and is therefore considered a puritan alloy. Monel was named after company president Ambrose Monell, and patented in 1906.
