1 Answer

Answer :

Ductility

 Ductility is the ability of a material to deform plastically without fracture under tensile load.

 Because of this property , materials can be drawn out into fine wire without fracture.

 It is therefore an indication of how soft or malleable the material is.

 The ductility of steels varies depending on the types and levels of alloying elements present.

 An increase in carbon , for example will increase the strength of material but decrease the ductility.

Malleability

 It is the ability of a material to deform plastically without fracture under compressive load.

 Because of this property , metal s are hammered and rolled into thin sheets.

 Malleable material can be flattened into metal leaf.

 Many metals with high malleability also have high ductility.

 Exmples of malleable metals are gold , aluminium , copper etc.

 Gold and silver are highly malleable.

 Malleable metals usually bend and twist in various shapes.
