metals

• types of metals:

  • ferrous
  • non-ferrous
  • alloys
• ferrous = contains iron
• non-ferrous = doesn't contain iron
• alloys = contains one or more metals/elements
• types of ferrous:

  • mild steel
  • cast iron
  • steel
• types of non-ferrous:

  • aluminium
  • copper
  • tin
• types of alloys:

  • stainless steel
  • solder
  • bronze
• properties of ferrous:

  • magnetic
  • prone to rust (has iron)
  • good strength
• properties of non-ferrous:

  • doesn't rust (no iron)
  • weaker than steel
• alloys can improve properties/characteristics of the base metal eg. strength, hardness, corrosion resistance
• stainless steel is steel + chrome so it doesn't rust and very strong
