Question:
Which of the following alloys do NOT have copper as one of the constituent metal?
Which of the following alloys do NOT have copper as one of the constituent metal?
Show Hint
Common copper alloys:
- Brass = Cu + Zn
- Bronze = Cu + Sn
- German silver = Cu + Ni + Zn
- Solder = Pb + Sn (no Cu)

- Brass
- German Silver
- Bronze
- Solder
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Alloys are mixtures of metals (or metals with non-metals) designed to enhance properties. Many common alloys contain copper as a major component.
Step 1: Check composition of each alloy.
• Brass → Copper + Zinc
• German Silver → Copper + Nickel + Zinc
• Bronze → Copper + Tin
• Solder → Lead + Tin (no copper)
Step 2: Identify alloy without copper.
Only solder does not contain copper.
Step 3: Final conclusion.
Thus, the correct answer is: \[ Solder \]
