7005 aluminium alloy

From Wikipedia, the free encyclopedia

7005 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[edit]

  1. 7005-O
  2. 7005-T5
  3. 7005-T53
  4. 7005-T6 [5]
