| Ferrous | Iron is soft and ductile, making it commercially un-useful. When you mix iron with carbon the characteristics are greatly improved. Increasing the carbon content will make the material harder, reduce toughness and ductility. |
| Ferrous Mild steel (properties) | -Ductile -Malleable -Tough -High tensile strength -Poor resistance to corrosion |
| Ferrous Mild steel (uses) | -Nuts -Bolts -Washers -Car bodies -Panels for cookers |
| Ferrous High carbon steel (properties) | -Very hard -Brittle -Difficult to cut -Poor corrosion resistance |
| Ferrous High carbon steel (uses) | -Hand tools -Chisels -Plane blades |
| Ferrous Cast iron (properties) | -Smooth skin -Strong when compressed -Self lubricating -Can't be bent or forged |
| Ferrous Cast iron (uses) | -Machine parts -Brake discs -Engines |
| Ferrous High speed steel (properties) | -Very hard -Heat resistant -Remains hard when red |
| Ferrous High speed steel (uses) | Tools eg. drill bits |
| Ferrous Stainless steel (properties) | -Tough -Hard -Corrosion resistant -Wears well -Difficult to cut, bend and file |
| Ferrous Stainless steel (uses) | -Cutlery -Sinks |
| Non-Ferrous Aluminium (properties) | -Good strength to weight ratio -Ductile -Malleable -Resists corrosion -Conducts heat and electricity well |
| Non-Ferrous Aluminium (uses) | Kitchenware |
| Non-Ferrous Copper (properties) | -Tough -Ductile -Malleable -Conducts electricity well -Corrosion resistant -Solders well |
| Non-Ferrous Copper (uses) | -Electrical contacts -Pipes -Wires |
| Non-Ferrous Tin (properties) | -Weak -Soft -Malleable -Ductile -Excellent corrosion resistant -Conducts electricity well |
| Non-Ferrous Tin (uses) | Coating of steel plates in tin cans |
| Non-Ferrous Lead (properties) | -Soft -Malleable -Very heavy -Corrosion resistant -Low melting point -Casts well -Conducts electricity well |
| Non-Ferrous Lead (uses) | -Adjoining brickwork -Roof coverings |
| Alloys Benefits of alloying metals | -Changes the melting point -Changes the colour -Increases strength, hardness and ductility -Enhances resistance to corrosion and oxidation -Changes electrical and thermal properties |
| Alloys Bronze (copper+zinc) | -Tough -Strong -Wears well -Good corrosion resistance Eg. Coins, statues, wheel bearings |
| Alloys Brass (copper+zinc) | -Quite hard -Rigid -Solders easily -Good conductor of heat and electricity Eg. Cast valves, taps, boat fittings |
