Message: [QUOTE="TrickTruck, post: 805013, member: 6044"] The problem with aluminum is that it turns into peanut butter where you weld it. Really, 6 series T6 alum has a yield strength in the mid 30s, that's nearly the strength of mild steel, so inch for inch, you are about equal in strength at 1/3rd the weight. Problem is that when you weld it you lose the T6 and it drops into the peanut butter category, a paltry 8ksi yield, less than a quarter of it's T6 strength. The trick would be building it from Alum and then restoring it's T6 rating, without having it warp to the point of being unusable. At which time you'd have something with the strength of mild steel at 1/3rd the weight. In $$ it would probably be somewhere between half again or double the price of steel. No, I haven't considered it at all:D [/QUOTE]
