Tube chassis question

[zeroaxe]

IIRC, aliminium also 'work hardens' and then starts cracking, no?

That makes sense, I was wondering why no one else was running aluminum when it is about one third of the weight. Thanks for the information everyone I definitely appreciate it.

There's no reason why a frame should not be made out of aluminium but it requires the design capability of a fully fledged chassis engineer to factor in the loads, strength, fatigue values etc, etc. Commercial aircraft are built mostly of aluminium and they are subject to substantial forces. There were early failures until the engineers understood more about metalurgy.
