Age-hardening - A slow hardening process which takes place in certain alloys. particularly those of aluminium, when allowed to stand at room temperature after annealing If you wish to work the metal after it has become age-hardened, it must be re-annealed Duralumin age-hardens in five days, Brittleness - Liability to break under a sharp blow. Cast iron and heat-hardened high-carbon steels are extremely brittle., Conductivity - Capacity to transmit heat and electricity- Copper, silver and pure aluminium are good conductors., Ductility - Ability to be stretched into fine wire without fracture: copper is highly ductile, Elasticity - Ability to regain original shape after deformation Lead is very malleable but has little elasticity- it does not spring back when bent, Fusibility - Property of becoming liquid when heated. Different metals have different melting points., Hardness - Resistance to deformation, scratching , bending and cutting ., Malleability - Capacity to be rolled, hammered or beaten into thin sheet without fracturing Gold is the most malleable metal, and can be beaten into leaf 0 .01 of a mm thick, Tenacity/Cohesion - Toughness or resistance to a pulling force-the opposite to ductility., Work-Hardening - Hardening of metal by being hammered or bent. The hardening causes the metal to become more brittle. and it must therefore be annealed to prevent it from cracking.,
