Aluminium alloy 2030 has similarities to the following standard designations and specifications:

AU4Pb,  Alloy 2030,  UNS A92030, ASTM B211

DIN AlCuMgPb,  3.1645,  ISO AlCuPbMg, 




2030 is supplied in a wide range of tempers:
T351 is intended to provide material with low residual stresses and thus minimal distortion during machining, but does not provide optimal corrosion resistance.

  • O - Soft
  • T3 - Solution heat treated, cold worked and naturally aged
  • T4 - Solution heat treated and naturaly aged to a substantially stable condition
  • T351 - Solution heat treated then stress relieved by stretching. Equivalent to T4 condition.
  • T4510 - Solution heat treated and stressrelieved by stretching - Equivalent to T4 condition
  • T4511 - Solution heat treated and stressrelieved by stretching - Equivalent to T4 condition



Alloy 2030  is supplied in bar, round bar, tube, profile and extrusions.

  • Bar / Round Bar
  • Tube / Profile / Extrusions
