Ordinary electrical conduit is steel.



Not these days but it wasn't suitable for the task anyway as it was
split rolled steel conduit.

Where do you guys live where they allow plastic conduit?  In New York
I've never seen it.

Different countries, different rules. Been the norm here in *housing*
for decades.

You think rolled would break down the seem if you flatten the end?  A
hole drilled on the sides first would keep a crack from spreading.

The rolled type formerly used in housing here was open seamed, the
rolled ends coming together but not welded. I haven't seen it in use for
decades now.

They used to use both split and welded seam but stopped split a long
time ago which had special fittings with screw clamps ,they still use
screwed steel conduit in special areas like flameproof and for
mechanical protection in industry.
A mate works as a *hazardous area gaseous environment* inspector in the
petroleum industry and they use threaded steel conduit exclusively with
all connectors being gas sealed along with all junction boxes,
instrument cabinets and the like. All electrical equipment must be
isolated from the atmosphere due to the potential presence of flammable
gases. Everything electrical is sealed up tight to isolate sparks from
the general environment.

We have had that for several decades.

Electricians here have an art for bending steel conduit exactly the way
they need it. With plastic I suppose they need to assemble more pieces
and use a selection of standard bends.
When I was a wee tacker, my family was in the building business and I
used to see all sorts of things. Back then the conduit I saw couldn't be
bent since it would kink and split open. It had, like the plastic
conduit, premade bends and connectors with, IIRC, inbuilt clamps to
connect to adjacent pieces. I'm going back a good 50 years there though
and that was in business premises, not residential.

They even install steel conduit here for low voltage wiring in many
places, but usually not for the whole distance. They could use plastic
but apparently choose not to. Our steel conduit looks seemless in some
cases, and with a smooth welded seem in others.
You will find, in most cases of variation, that it is local ordinances
that are the cause.

OK, thanks guys.

I think I'll try the annealing approach first with aluminium. If it
breaks again, I suppose I'll have to have go at the same method but
with steel.

Don't waste your time.

Whoever suggested annealing it is clueless as annealing aluminium is a

You *know* who suggested annealing Noddy. Sylvia was, quite naturally,
thinking along the same lines. But thanks for proving yet again that you
read *e v e r y s i n g l e w o r d I w r i t e*

> very complex process compared to other metals such as steel or copper,

Complex? Who are you kidding? The *process* is detailed on the link *I*
provided. Hardly complex, except maybe to you.

and unless you know what type of aluminium you're using and what
temperature to heat it to then you're going to achieve absolutely nothing.

The method of temperature assessment provided in the link serves to
determine the *appropriate* temperature regardless of the grade of
aluminium.
The problem, as mentioned previously, is that you're using the wrong
material for the device you're making. Aluminium tube does *not* like to
be crushed and bent as you're doing, and no amount of "home annealing"
will help you as aluminium needs to be heated to near melting point to
achieve any kind of pliability.

FWIW, the correct term is *ductility*.

All annealing, regardless of the material requires heating to near
melting point. That is the whole point of the annealing process - heat
the material *above* its *crystalisation temperature*. Any material that
is extruded is work hardened so annealing serves to normalise the
crystal lattice. The aim here is to improve the ductility of the material.


Quite simply, it is far to brittle a material to do with what you're
looking to do,

How do you know what the task is? It wasn't detailed.

and all you'll manage to make is something that will fail like it
already has.

Work hardening will make most metals more brittle. Aluminium, in its
normalised state, is quite a ductile material.
You'll get far better results using thin wall steel tube while will be
just as easy to form and bend and it can be done cold to the point you
have in the picture without hurting it. Better yet get some 30x5 flat
bar cut to length, bent and drilled as required and your problems will
be solved forever.

Don't listen to me thought. Waste shitloads of time and money on
something that can be fixed for 10 bucks worth of steel from Bunnings :)

One could ask why you intend to waste money on restoring a rusty car
body that has absolutely no cachet, its only value being as scrap metal
at Sims.

Yeah, I haven't seen it for yonks. It was common enough when I was a kid
but as rare as rocking horse turds now.

and for mechanical protection in industry.

When my mate was staying here for a few weeks, he gave me a lot of info
on what went on in those environments - critical stuff. Probably why he
gets $300k per year. He only works part time these days however since he
now lives in China. Doing a job on Barrow Island, $65k for 6 weeks.

I've never heard it called 'screwed'. It is called threaded, rigid conduit every area that I've lived. It is the same as black iron water pipe, but with no ridge from the welding inside to pipe to damage the insulation. All it takes is one bad spot inside the pipe to strip the insulation enough to short it to the conduit.

New York uses steel because it takes longer to install, and all of their electricians are required to be in the union.

They won't use PVC in damp locations, which can cause EMT to rust through. Some areas use extruded aluminum conduit, or even stainless around food processing plants like the Orange Juice processing plant near here.. I caught my dad chopping up new aluminum conduit that I was saving for a project. He had no idea what it was, so it was automatically scrap. It had a little surface damage from being stored in an outside rack, but it wholesaled for $70 for a ten foot section. I managed to save five sections, out of 20. The largest commercial electrical contractor in the area was cleaning up their inventory, and gave me trailer loads of Rigid, EMT, PVC and aluminum that was shop worn. I was writing specs for them for networking, MATV and other applications that they normally farmed out to smaller companies. I asked for a couple pieces of conduit, and was given all if it.

You bend electrical PVC with hot air guns. Quite handy for odd offsets, like conduit inside a concrete block wall, and it comes out of the floor in the wrong spot.. Keep in mind that you are limited to a total of 360 degrees in a run of conduit without a pullbox to split it into two runs.

golf clubs shafts are still steel. unless they're graphite of course.
