Aluminium Alloy BS L167 2014A-T6 Clad Sheet

Technical Data Sheet

Aluminium alloy BS L167 is the aerospace specification for 2014A-T6 Alclad sheet and strip. In order to combat 2014A's poor corrosion resistance, L167 is clad with pure aluminium. L167 is the same alloy as L165, and will always meet the chemistry and mechanical requirements for both, but is produced to tighter rolling tolerances. L167 / 2014A is alloyed with copper (3.90-5.00%) giving it high strength, which it retains after its heat treatment. As such L165 finds usage in many aerospace and defence high strength applications. Aircraft Materials stocks L167 in a wide range of sheet thicknesses ready for same day shipment. Many stock items can be dual-certified to both L167 and L165.
