7005 aluminium alloy

70935097005 is an aluminium wrought alloy[1] used in bicycle frames , due to its relative ease of welding it does not require expensive heat treating - it is however harder to form making manufacture more challenging. [2] It has an Ultimate Tensile Strength of 350 MPa, a Fatigue Strength of 150 MPa and a density of 2.78 g/cm³. [3] It does not need to be precipitation hardened, but can be cooled in air. [4]

Specific forms of AL 7005 include:
  1. 7005-O
  2. 7005-T5
  3. 7005-T53
  4. 7005-T6 [5]
