The World of Metals and Non-metals — Science STD 7 — Question

To test ductility, gather a copper wire and aluminum foil. Using pliers, gently stretch the copper wire to see if it can be drawn into a thinner strand without breaking. Then, try stretching the aluminum foil by hand to observe if it stretches or tears. The material that stretches more without breaking is more ductile, demonstrating its ability to be drawn into a wire.
