Question

Explain the meaning of malleability and ductility?

Answer 1

Malleability is the property of metals which enables them to be beaten into thin sheets with a hammer (without breaking). For example, if a piece of aluminium metal is taken and beaten with a hammer four or five times, the piece of aluminium metal is turned into a thin aluminium sheet, without wreckage.

Ductility is the property of metals which enables them to be drawn (or stretched) into thin wires. For example, gold is the most ductile metal. Just 1 gm of gold can be drawn into a very thin wire about 2 kilometers long.
