What are some properties and uses of mild steel?
Ductile, high tensile strength, tough, malleable, poor resistance to corrosion
Nuts, bolts, washers, screws
What are some properties and uses of medium carbon steel?
Harder than mild steel but less ductile, malleable, tough
Springs, gardening tools
What are some properties and uses of cast iron?
Harder outer skin but brittle core, good under compression
Disc brakes, machine parts

What are some properties and uses of aluminium?
Lightweight, ductile, malleable, corrosion resistant
Drinks cans, aircraft bodies, bike frames
What are some properties and uses of zinc?
Good corrosion resistance, low melting point
Protective coating for bins/buckets/gates
What are some properties and uses of tin?
Ductile, malleable, tough, good corrosion resistance, low melting point
Soft solder, food can coatings
What are some properties and uses of copper?
Ductile, malleable, tough, corrosion resistant, good electrical and thermal conductor
Electrical wire, water pipes, central heating pipes
What is the melting point and metal combination of stainless steel?
1510 degrees Celsius
18% chrome, 8% nickel
What is the metal combination of duralumin?

What are some properties and uses of stainless steel?
Tough, hard, corrosion resistant
Sinks, kitchenware, cutlery
What are some properties and uses of duralumin?
More lightweight, ductile, becomes harder as worked
Aircraft and vehicle parts
What are some properties and uses of brass?
Corrosion resistant, good electrical and thermal conductor, low melting point
Boat fittings, door furniture, cast taps, ornaments
