Monel is a trademark name for which family of alloys?

• A. Nickel-copper alloys
• B. Nickel-chromium alloys
• C. Copper-tin alloys
• D. Titanium-vanadium alloys

Answer: (A)

Monel designates a family of nickel–copper alloys. The defining feature is the combination of nickel with copper, which gives good ductility and toughness along with excellent corrosion resistance, especially in seawater and many chemicals. The classic Monel alloy, Monel 400, is roughly 60–70% nickel with the remainder copper, plus small amounts of other elements that enhance strength. This distinguishes it from other alloy families: nickel–chromium alloys are designed for high-temperature oxidation resistance, copper–tin alloys are bronzes, and titanium–vanadium alloys are used for high-strength, lightweight structural applications. So the nickel–copper alloy family is the one referred to by Monel.
