Non-Ferrous Metals

Non-ferrous metals are commonly used in everyday objects such as take away trays. They could even be used in some of your GCSE projects.

Aluminium

Aluminium

  • Light grey in appearance with a matt or polished surface finish.
  • This metal is lightweight, ductile and has a high strength to weight ratio.
  • Aluminium can be difficult to weld.
  • Common uses include drinks cans, pot and pans, bike frames, and take away trays.
Copper

Copper

  • Bright reddish orange in appearance and can be polished to a high quality finish.
  • This metal when oxidised will turn to an attractive mottled green shade.
  • Copper is malleable, ductile and a good electrical conductor.
  • Common uses include copper pipes for heating, pots and pans, electrical cable, roofing and guttering.
Tin

Tin

  • Silvery grey in appearance with a shiny finish.
  • This metal is often plated onto steel and is soft and malleable.
  • Tin is a good electrical conductor.
  • Common uses include tin cans, soft solder, mixed as an alloy with copper to create bronze.
Zinc

Zinc

  • Silvery grey in appearance with a matt finish.
  • This metal is malleable, ductile and a good conductor of electricity.
  • Common uses include the process of galvanising to coat steel to protect it from rusting.

Alloys

Alloys are commonly used in everyday objects such as cutlery. They could even be used in some of your GCSE projects.

Brass

Brass

  • This alloy is made up of 65% copper and 35% zinc.
  • Brass is yellow/gold in appearance and goes brown when it oxidises (rust).
  • A heavy alloy that is malleable, easy to cast and has low friction.
  • Common uses include ornaments, musical instruments and plumbing fittings.
Stainless steel

Stainless steel

  • This alloy is made up of low carbon and chromium.
  • Stainless steel has a bright polished mirror finish and can resist rust.
  • A ferrous alloy with chromium, nickel and manganese that is hard and smooth.
  • Common uses include kitchen sinks, cutlery and medical equipment.
High speed steel

High speed steel

  • These alloys can include chromium, molybdenum, tungsten, vanadium, cobalt and carbon.
  • The appearance can vary depending on the mixture of alloy with steel.
  • This alloy performs well under high temperatures when used for machining.
  • Common uses include drill bits, cutting tools, mill bits, taps and dies.
