Which alloy is used in making ships and marine equipment due to its resistance to corrosion by seawater?
medium Q7 of 15
Step-by-Step Solution
Step 1: Understand the concept
The question tests knowledge of alloys resistant to corrosion in marine environments.Step 2: Apply the concept
Bronze, an alloy of copper and tin, is highly resistant to corrosion by seawater, making it suitable for marine equipment. Brass corrodes faster, steel rusts, and duralumin is used in aircraft.Final Answer:
Bronze → Option CQuick Check:
Marine corrosion-resistant alloy = Bronze ✅
Quick Trick: Tin in bronze prevents corrosion in seawater.
Common Mistakes:
- Confusing brass or steel as corrosion-resistant in seawater.
