Default Aluminum bending

I have some aluminum stock with an airfoil cross-section, but it is to thick for my application. It has a chord length of 1 5/16", thickness of 1/2", and it welded at the leading and trailing edges. I am trying to get it down to 1/4", but it springs back when I try to compress it and I don't want to crack the welds.
Any ideas?

i am not sure so don't take me at my word but i know heating and quenching softens some metals but i am unexperienced with aluminum. so it might soften it or it might make it brittle. if you have a small sample of it you might try it.

We use aluminum and copper for bonsai. A slow heat, like buring straw, to heat the rod up and then bend to shape and let air cool.
