ALUMINIUM

AVIONAL 2011 - 2007

print version

9002/5- 2011 - DinAlCuBiPb - EN AW 2011

This alloy is the most often selected for high speed automatic lathes. It offers the following advantages:

  • easy machining with any equipment;
  • cutting stress lower than most of other alloys;
  • better allowances and better finishing on the surface of turned parts;
  • longer life of cutting tools;
  • cutting area always clean due to very thin chip;
  • high mechanical properties.

11S 9002/5 is the most recommended alloy to fast and easy machining.
