Superalloys: nickel content comparison between Nimonic and Inconel Complete the statement about Ni content: “Nimonic contains __________ percentage of nickel as compared to Inconel.” Choose the best completion.

Difficulty: Easy

A lower
An equal (about the same)
A higher
Approximately half the

Correct Answer: A higher

Explanation:

Concept
Nimonic grades are typically very high in Ni (often ~70–80% for classic grades like Nimonic 75), whereas common Inconel grades span ~50–72% Ni depending on type (e.g., 718 ~ 50–55%, 625 ~ ~60%, 600 ~ ~72%). Hence, in general wording, Nimonic contains a higher percentage of nickel than Inconel.

Final Answer
A higher
