Try asking Boeing...they make loads of stuff out of aluminum!  So what are you making out of aluminum?  If it's a neck just try flexing it by hand, that will give you a good idea of how strong it is....

Can you bend a 36" length of that tubing with your hands? I doubt it. You'll be fine for a diddley bow.

Aluminum strength depends on the alloying and production method, for example 7000 series aluminum is comparable to steel of similar dimensions.

Of course the simplest way to determine if the piece you have will work is to just go ahead and build it. If it doesn't work you can always reuse the parts in another project.

It will be fine I'm sure, I've built a diddley bow with 20mm alu "U" section with a softwood insert in the back of it. Of course it will bend, all materials do, but as long as it doesn't bend too much, all will be OK. Stop thinking about it and make it.
