Question 219General Subjects - Assistant Engineer

The correct answer is A) nickel and copper. Monel metal is an alloy composed mainly of nickel and copper. It is a corrosion-resistant alloy that is commonly used in marine applications due to its strength and resistance to seawater. The high nickel content, typically around 60-70%, gives Monel its distinctive silvery-white appearance and excellent corrosion resistance. The other answer choices are incorrect because: B) zinc and copper is a brass alloy, not Monel. C) bronze and tin is a type of bronze alloy, not Monel. D) copper and tin is also a type of bronze alloy, not Monel.
