Unit 3

Materials	Properties	Uses
Metals
Aluminium	Light, soft, ductile, highly conductive, corrosion-resistant	Aircraft, engine components, foil, cooking utensils
Copper	Very malleable, tough and ductile, highly conductive, corrosion-resistant.	Electric wiring, PCBs, tubing
Brass(65% copper, 35% zinc)	Very corrosion-resistant. Casts well, easily machined. Can be work hardened. Good conductor.	Valves, taps castings, ship fittings, electrical contacts
Mild steel (iron with 0.15 % to 0.3 % carbon)	High strength, ductile, tough, fairly malleable. Cannot be hardened and tempered. Low cost. Poor corrosion - resistance	General purpose
High carbon steel (iron with 0.7 % to 1.4 % carbon)	Hardest of the carbon steels but less ductile and malleable . Can be hardened and tempered.	Cutting tools such as drills, files, saws

In this table I can see 5 kinds of MATERIALS. They are Aluminium, Copper, Brass, Mild steel and High carbon steel.

Aluminium is light, soft, ductile, highly conductive and corrosion-resistant. It is used to make aircraft and engine components.
Copper is very malleable, tough and ductile. It is used to make electric wiring and tubing.
Brass is very corrosion-resistant. It is easily machined. It can be work hardened. It is used to make valves, taps castings and ship fittings.
Mild steel has high strength. It is ductile, tough and fairly malleable. It can not be hardened and tempered. It is used for general purpose.
High carbon steel is the hardest of the carbon steels but less ductile and malleable. It can be hardened and tempered. It is used to make cutting tools such as drills, files and saws.
That is all the information about the 5 kinds of MATERIALS that I know
