i bought some tubing from a hardware store but it burst what kind of tubing do i need ? thickness of wall do i need? would stainless steel be cheaper .? i need to make the end bend in the shape of a hook for cleaning gutters my pressure washer is 2900 psi no go and amaze me this is why i come here .
Aluminum cannot handle high pressure all that well as you have seenIt will handle 2900 PSI if the wall thickness is thick enoughMy guess is your first tube burst at the bendBending the metal will weaken itAluminum is not very ductile (bendable) so it tends to fracture easily when it is bentYou will have this problem even with a thicker wall tubeStainless steel would be far stronger and with the right wall thickness could easily handle the pressure and bendingThe BIG drawbacks are the it is very hard and not easy to bend and also is very heave compared to aluminumA 16 ft piece of 1/8 wall tubing would weigh more than 40 lbsNot something you want to lug around all dayThe only thing I know that is light enough and strong enough is composite materialsThey cannot be bent after they are laminated up so the bend would have to be part of the manufacturing processVery, very expensiveGood luck
