2.25C: Explain the Uses of Aluminium, Copper, Iron and Steel in Terms of their Properties: the Types of Steel will be Limited to Low-Carbon (Mild), High-Carbon and Stainless

USES OF ALUMINIUM:

USE	MOST IMPORTANT PROPERTY
AEROPLANE BODIES	High strength-to-weight ratio (low density)
OVERHEAD POWER CABLES	Good conductor of electricity
SAUCEPANS	Good conductor of heat
FOOD CANS	Non-toxic
WINDOW FRAMES	Resistant to corrosion

s

USES OF COPPER:

s

USE	MOST IMPORTANT PROPERTY
ELECTRICAL WIRES	Good conductor of electricity and malleable
WATER PIPES	Good conductor of heat and unreactive (does not react with water)

s

USES OF IRON:

s

USE	MOST IMPORTANT PROPERTY
CAR BODIES	Strong (withstands collisions)
IRON NAILS	Strong
SHIPS, GIRDERS AND BRIDGES	Strong

s

USES OF STEEL:

s

TYPE OF STEEL	USE	MOST IMPORTANT PROPERTY
LOW CARBON STEEL	CAR BODY PANELS	Malleable
HIGH CARBON STEEL	CUTTING TOOLS	Hard and strong
STAINLESS STEEL	CUTLERY AND SINKS	Resistant to corrosion
