Ductility:
It is the property of metals of being drawn into wire. It is a desirable property in machine components that are subjected to unanticipated overloads or impact loads. The ductility of metals decreases as the temperature increases because metals become weak at increasing temperature.
Examples: copper, aluminium, steel, gold.
Malleability:
It is the ability of the material to deform to a greater extent before signs of cracks appear when it is subjected to a compressive force. In general, malleability increases with an increase in temperature. Processes like forging or rolling gives shapes to hot ingots or slabs.
Examples: gold, silver, iron, aluminium, copper, lead.
