Question:
Identify the type of defect in brass alloy.
Identify the type of defect in brass alloy.
Show Hint
Brass (Cu + Zn) and Bronze (Cu + Sn) are classic examples of substitutional alloys.
Updated On: Apr 26, 2026
- Interstitial impurity defect
- Schottky defect
- Substitutional impurity defect
- Metal deficiency defect
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Alloys like brass are formed when atoms of one metal replace atoms of another metal in the crystal lattice.
Step 2: Application
Brass is an alloy of Copper ($\text{Cu}$) and Zinc ($\text{Zn}$). In its structure, Zinc atoms substitute some of the Copper atoms in the lattice positions.
Step 3: Conclusion
Since host atoms are replaced by impurity atoms, it is a substitutional impurity defect.
Final Answer: (C)
