The linear solidification shrinkage of Type IV Ni-Cr based alloys is_______________?
Correct answer: A. 2.3%
- A. 2.3%
- B. 1.56%
- C. 1.37%
- D. 3%
Explanation
Type IV nickel-chromium alloys show approximately 2.3% linear solidification shrinkage. This relatively high value compared with noble alloys must be allowed for in pattern and casting design.
