Which non-ferrous alloy is noted for corrosion resistance and good thermal and electrical conductivity?

• A. Copper
• B. Brass
• C. Aluminium
• D. Tin

Answer: (B)

Think about a material that both conducts well and resists corrosion. Brass fits this well because it’s a copper–zinc alloy. The copper gives good electrical and thermal conductivity, while adding zinc improves mechanical properties and keeps the surface fairly resistant to corrosion in many environments. Pure copper would be the best conductor, but since the question asks for an alloy, brass is the strongest match among the options. Aluminium is corrosion-resistant but its conductivity isn’t as high as brass in this context, and tin is a poor conductor, so brass best satisfies the combo of corrosion resistance with good thermal and electrical conductivity.
