Improved Can Body Stock

• Thinner

  • Downgauge further

• Good strength

  • Solid solution strengthening, strain hardening
  • Controlled by alloying and thermomechanical processing
  • Strength limited by customer tooling performance

• Galling control

  • Need for continuous die cleaning for good can surface
  • Believed to be controlled by correct size and amount of alpha phase

• Earing control

  • To minimise metal wastage after D&I process
  • Controlled by alloying and thermomechanical processing

• Cost

  • Controlled by cost of alloying additions and final gauge
