Why are EMT conduit bodies aluminum?
Am I just missing the steel ones or are all EMT conduit bodies aluminum? All the EMT I've seen was steel, and my EMT couplings are steel, but I found two sources for the bodies and they're aluminum. I'll settle for aluminum, but I don't get it.

You're just missing them. The mega-mart big box homecenters generally don't stock the steel or cast iron bodies and often don't even stock all the varieties of conduit bodies.
Also, most of what you might think are aluminum conduit bodies and connectors are in fact made from an alloy known as Zamak which is primarily zinc. These are made by a process called die casting and the material is also generically called pot metal.

I'll keep looking 
. Type C wasn't so easy to find either, and I don't think my local big box store had any EMT bodies.

The website of my local electrical distributer ("... Electrical Supply Corp.") says they carry the complete line of products from the listed manufacturers. I checked the websites of four relevant manufactures. One has what I want, except it's aluminum and the other has what I want, except it's non-metallic. The shelf quantity/box quantity of each is 10. If I could buy one aluminum one from them, I'll be lucky.

3/4", type C, set screw, unthreaded. I wanted steel or malleable iron or whatever's most appropriate for common EMT. Now it looks like aluminum is ususally used and I've been told there's no reason not to get the aluminum. I'd still prefer steel because it may be thinner which may help in my situation, but I'm done looking.

If you use steel compression connectors, which has its own value, you can use a conduit body with threaded inlets.
Bridgeport makes a good selection of conduit bodies. Not 3/4" in steel, though, as far as I could tell.

I always think of Bridgeport as an economy brand, but think more of Appleton, Killark and Crouse-Hinds more as commercial/industrial brands.
