$\Large{ \boxed{ \bold{ \red{Malleability}}}}$

Malleability is the physical property of in which they can be beaten into thin sheets of metal without breaking. The metals are hammered and turned into thin foils or sheets. Most of the metals are malleable except some brittle and soft metals like Na, K, etc.

✦ Most of the metals are malleable. The most malleable metals are Gold and Silver. Copper and Aluminium are also highly malleable metals.

$\Large{ \boxed{ \bold{ \red{Examples:}}}}$

✦ The malleability of metals has shown a lot of advantages in the preparation of many items like foils, Jewelleries etc.

• Gold is a yellowish metal used in jewelleries and ornaments. They are the most malleable metals. Due to this property, they are used to make jewellers of Required Shapes.
• Similarly, Silver is also a highly malleable metals used for making jewelleries. Silver foils are also used in the decoration of sweets.
• Aluminium is used to make kitchen foils which are used to wrap food items in order to keep them warm for longer time.
• Copper is used in making electric items like used in making appliances or wires.
