The tooling chart below details what  we can bend with our current tooling and with 1.6mm wall aluminium tube that we stock.

Other Aluminium wall thicknesses such as 1.2mm and 0.9mm are available, but the achievable bend angles may change (maximum bend angles are in the yellow cells which also indicate what tooling we have).
 
If you need bends and tube sizes not on this chart, please email us at info@goodfabs.com and we'll see if we can accommodate you.
