Explain the following: i Malleability ii Ductility iii. Toughness iv. Fusibility – NABTEB QUESTION

i Malleability: It is the ability of a metal to be bent, rolled or formed without fracture. E.g. steel, aluminum.

ii Ductility: It is the ability of a metal to be drawn into thin wire e.g. copper.

iii. Toughness: Ability of a metal to resist sudden heavy load without fracture. E.g wrought iron.

iv. Fusibility: Ability of metal to turn into liquid when heated to sufficient temperature e.g. cast iron

v. Brittleness: Ability of metal to break when sufficient load is applied e.g. cast iron.

vi. Conductivity: Ability of metal to allow easy passage of heat or electricity.
