1.5 " Alum. conduit $1.20 a foot Unbendable anodized alum. $5 a foot. As far as I can tell the only difference is the anodizing. I have tested both by hanging weight on a length of pipe. The ID of the conduit is consistant. What is the difference?

Hardness of the metal is the big difference. The conduit will bend without cracking.....depending on how sharp you bend it.

Depends on which anodized pipe you are comparing it to. Do you really have electrical aluminum conduit? If so, is it standard rigid size? I.E. Schedule 40? Sorry for all the questions, but there is a lot of differences in pipe and conduit wall thickness as well as alloy composition.

Yes it is conduit. Bought it at Contractor electric supply. It is as strong as the stuff NRS sells. I have a couple of their frames. It is the same ID and OD as NRS frame pipe

The difference is the inertial characteristics. Measure with calipers to the 0.001 in. The second area moment
(Moment of inertia) is 3.14159 x (Do^4-Di^4)/64 The value for most 1.5" pipe is 0.31 in^4 1.25" pipe is somewhere around 0.195in^4 The conduit you have is somewhere around 0.16 in^4
However, conduit is made for bending and its alloys are soft and ductile (capable of high strain in tensile regime).
The 1.25 pipe is available for @$2.50/ft and the 1.5 is available for $3/ft in small quantity.

That conduit is good for kitchen tables. There are not many fittings to construct to that size so you should be ready to weld it.

That explains a lot, no sane person should be doing that kind of math at 4 am. I'm sure op will appreciate it in a few hours.
