Answer:

Malleability: It is the ability of the material to withstand rupture under compression as in hammering or rolling into a sheet.

• It does not depend on strength.
• Malleability increases with the rise in temperature.

Ductility: It is the ability of a material to withstand permanent deformation under a tensile load without rupture. A metal that can be drawn readily into a wire is said to be ductile. Ductility depends on tensile strength.

Application of Malleability and Ductility:

• Gold is the most ductile and malleable metal. This property enables manufacturers to beat it into thin foil.
• Silver is a second ductile and malleable metal. Among other metals, platinum ranks third in ductility, and copper ranks third in malleability.

Significance of Ductility and Malleability:

• Ductility and malleability are important properties of metals, alloys, and a few plastics.
• The more the metal is ductile, the better its perishability.
• Metals with good ductility have good marginal adaptability and decrease marginal leakage.
• If a metal can be compressed or elongated, it has good ductility and malleability.
