Admiralty brass used for steam condenser tubes contains copper and zinc in the following ratio
A. 50 : 50
B. 30 : 70
C. 70 : 30
D. 40 : 60
Answer: Option C
Solution (By Examveda Team)
The correct answer is Option C: 70 : 30.Let's break down why:
Admiralty brass is a specific type of brass alloy.
Brass is primarily made of copper and zinc.
Admiralty brass has a typical composition of approximately 70% copper and 30% zinc, and also contains a small amount of tin (around 1%) to improve corrosion resistance, especially in seawater applications like steam condensers.
Therefore, the ratio of copper to zinc in admiralty brass is closest to 70:30.
The other options are incorrect because they do not reflect the standard composition of admiralty brass.
