Properties and Uses of Iron, Aluminium, Copper and Titanium

Properties and Uses of Metals


  • High strength under compression and tension, making it ideal for structural engineering.
  • Malleable and ductile, meaning it can be shaped and bent without breaking.
  • Prone to rust when exposed to moist air. The corrosion process oxidises the iron, making it brittle and flaky.
  • Used to make steel, an alloy with carbon, which is stronger and less prone to rusting.


  • Lightweight, making it ideal for applications such as aircraft where weight is crucial.
  • Highly resistant to corrosion due to formation of protective oxide layer.
  • Ductile, hence, can be rolled into sheets for packaging and can manufacturing.
  • Good electrical conductivity, aluminium wires are used in high-voltage transmissions.


  • Excellent electrical and thermal conductivity making it the metal of choice for wiring and heat exchangers.
  • It can be alloyed with tin to make bronze, which is strong and corrosion-resistant.
  • Malleable and ductile, hence, it is often used in decorative applications, like jewellery.


  • Exceptionally high strength-to-weight ratio, importantly used in aircraft and automotive industries.
  • Highly resistant to corrosion, must be considered for applications in hostile environments such as marine and chemical industries.
  • High melting point makes it suitable for use in jet engines and other high-temperature applications.
  • Bio-compatible, hence, used in surgical tools and implants.
