Key Info
  • The creation of duraluminium
  • Duration: 03:46
  • Mark Miodownik describes how Alfred Wilm's experimentation with alloys came up with duralumin in 1903. This alloy is a mixture of aluminium, manganese, copper and magnesium. A key part to this story is how Wilm discovered age hardening (alloys becoming stronger over time) by accident. Mark Miodownik describes the crystal lattice structure of alloys. First broadcast in 'How it works' on BBC Four in February 2010.
