“7005 aluminium alloy”的意思、由来-开放百科全书

7005 is an aluminium alloy used 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.

It has an Ultimate Tensile Strength of 350MPa, a Fatigue Strength of 150MPa and a density of 2.78g/cm³

compared to a Ultimate Tensile Strength of 310MPa and Fatigue Strength of 96.5 MPa and a density of 2.70g/cm³ for 6061 aluminium alloy.

It does not need to be precipitation hardened, unlike 6061, but can be cooled in air.^[3]
