Relative ductility comparison among common engineering metals Which listed material exhibits the highest ductility (greatest uniform elongation before fracture)? Choose the correct option.

Difficulty: Easy

Mild steel
Copper
Zinc
Aluminium

Correct Answer: Copper

Explanation:

Concept
Among the given choices, copper is notably ductile (high percent elongation and reduction of area). Mild steel and aluminium are ductile but generally lower than copper; zinc is comparatively less ductile and more prone to brittleness at room temperature.

Final Answer
Copper
