Ductility
Ductility is the property of the material that enables it to be drawn out or elongated to an appreciable extent before rupture occurs.
The percentage elongation or percentage reduction in the area before rupture of a test specimen is the measure of ductility. Normally if the percentage elongation exceeds 15%, the material is ductile, and if it is less than 5%, the material is brittle.
Lead, copper, aluminium, mild steel are typical ductile materials.
Brittleness
Brittleness is the opposite of ductility. Brittle materials show little deformation before fracture and failure occur suddenly without any warning, i.e., it is the property of breaking without much permanent distortion. Normally if the elongation is less than 5%, the material is brittle. E.g., cast iron, glass, ceramics are typical brittle materials.
Malleability
Malleability is the property by virtue of which a material may be hammered or rolled into thin sheets without rupture. This property generally increases with the increase of temperature.
Malleability is the ability of a metal to exhibit large deformation or plastic response when being subjected to compressive force.
Lead, soft steel, wrought iron, copper, and aluminium are some materials in order of diminishing malleability.
