Heating elements.

Does anyone know what the heating elements in dishwashers and in stoves are made of? I just took a dishwasher apart two days ago and I can't decide what it is made of. Also, does anyone know anything about thermo couple wiring? I asked my friend what this would be used in since he is a journeyman electrician and he said stoves and ovens were the only thing he could think of.... obviously he has never seen the stuff. Is this type in ovens?

If it is type K T/C the harness going to it should be a Chromel/Alumel wire. they are also used in Turbines Steam/Gas turbines. can also be used in Process Equipment Like Chillers & Boilers. Basically its a Temp Indicator.

The elements are made of something called cal rod. I just put them in my regular scrap steel bin

The elements in furnaces and old heaters are keepers they are made of I believe tungsten, I get around $5.00 a pound. Takes a long time to get a 5 gallon bucket filled but good payday when it's full.
