Aluminium alloy 2014 / 2014A is covered by Standard BS EN 2100 and has similarities to the following standard designations and specifications:

2014 / 2014A ,  AMS 4029,   ISO AlCu4SiMg,  DIN AlCuSiMn,  UNS A92014



The most common tempers for 2014 / 2014A aluminium are:

  • T4 - Solution heat treated and naturaly aged to a substantially stable condition
  • T6 - Solution heat treated and artificially aged
  • T651 - Solution heat treated, stress relieved by stretching then artificially aged
