What is Monel?

What is Monel?

• A. Nickel-copper alloys are known by this name, which is a trademark of the International Nickel Corporation
• B. A type of stainless steel used in food processing
• C. A polymer used as a plasticizer
• D. A ceramic composite

Answer: (A)

Monel designates nickel–copper alloys. It’s a trademarked name used for a family of corrosion-resistant metals originally marketed by the International Nickel Company. These alloys combine nickel and copper to give good strength and excellent resistance in many environments, especially seawater and various chemicals. It isn’t stainless steel, which is an iron-based alloy containing chromium; it isn’t a polymer, which would be a plastic material; and it isn’t a ceramic composite. So the best description is that Monel is a nickel–copper alloy identified by a trademark of the International Nickel Company.
