Bar 11S
EN AW 2011

The target sectors for the 2000 series alloys are mechanical turning workshops and manufacturers of hydraulic components.

Alloy 2011 or 11S was created to provide maximum workability on automatic lathes. The main alloying element is copper, which provides this alloy with excellent workability, a lower shear strength than the 6000 series alloys, and extremely fine shavings, making it ideal for all screw, bolt, and threaded rod applications.

technical characteristics

  • Workability: excellent
  • Resistance to atmospheric corrosion: good
  • Protective anodisation: sufficient
  • Plastic deformability: sufficient

Availability

The alloy 11S is available extruded in the physical state T6, and drawn in the physical state T3 and T8. Other physical states are available upon request.
