Which parameters used for ductility measurement. And why not copper the top ductility?

Ductility: gold > silver > iron > copper > aluminum > zinc > tin > lead.

Copper has about 60% more ductility than Aluminium.

Sai saketh said:   8 years ago
I think copper is more ductile material.

Kiran said:   8 years ago
I think Al is more ductlile than MS.
It has no carbon content so.

Dashrath said:   8 years ago
Because mild steel having less carbon than other materials.

Avey said:   8 years ago
No, Al is most ductile among all.

Amol Malode said:   8 years ago
The ductility of steel varies depending on the alloying constituents. Increasing levels of carbon decreased ductility.

The most ductile metal is platinum and the most malleable metal is gold.

Anand said:   8 years ago
Copper is more ductile than Mild steel.

Sreeram said:   9 years ago
Mild steel having more ductile behavioural phenomenal than the aluminium and reason is that;

Mild steel shows BCC crystal structure and Aluminium shows FCC.

And BCC is more ductile than FCC structure and one more best reason for why aluminium shows a less ductile than mild steel is. FCC crystal structure cannot show ductile to the Brittle transition temperature and only BCC can shows.

This is the main reason.
