7005 aluminium alloy
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[]
