metal alloys

carbon steel

• iron - 99.8%

• carbon - 0.2%

stronger than iron, more resistant to corrosion

→ making motor car bodies, construction materials

titanium alloy

• titanium - 90%

• aluminium - 6%

• vanadium - 4%

very strong, low density

→ making aircraft bodies, spacecraft bodies, glasses frames

bronze

• copper - 90%

• tin - 10%

harder than copper and tin, resistant to corrosion

→ making statues

brass

• copper - 70%

• zinc - 30%

harder than copper and zinc, more resistant to corrosion

→ making musical instruments, doorknobs, keys

duralumin

• aluminium - 95%

• copper - 3%

• magnesium - 1%

• manganese - 1%

stronger than aluminium, low density

→ making aircraft bodies

coinage metals

• copper

• zinc

• nickel

• tin

harder and shinier than copper, resistant to corrosion

→ making coins

carat gold

• gold (majorly)

• silver

• copper

harder and shinier than pure gold

→ making ornaments, coins

solder

• tin - 50%

• lead - 50%

lower melting point than tin and lead, harder than tin and lead

→ join electronic parts
