Investment Casting Factoid: What is a Monel?

Apr 30, 2019

Monel is a group of nickel alloys that can be used in the investment casting process to make parts that have specific characteristics. Monel was created by Robert Crooks Stanley, of International Nickel Company, in 1901. It was named after Ambrose Monell, the company president. The last “L” was dropped because family names were not allowed as trademarks at that time. Monel is composed of up to 67% nickel, copper, plus lesser amounts of manganese, carbon, iron and silicon. Monel alloys are generally stronger than pure nickel and have excellent resistance to many types of corrosion. It can stand up to both fire in pure oxygen and flowing sea water, making it very suitable for punishing applications in many industries and situations. While more costly than many alloys, monel brings valuable properties.
