Every now and then I get an odd piece of scrap that defies clear identification on which pile it belongs in.

Yesterday's problem for me came after taking apart a pile of electric motors. I had a small pile of ceiling fan stators that were cast aluminum with steel bands, but with indistinct boundaries between the metals. I also had a small pile of rotors taken from other motors. These rotors were solid pieces of similar construction, a mix of aluminum and steel.



I had these in the irony aluminum bin but they were all rejected by the scale man.

I know - the yard will buy what the yard will buy. BUT - has anyone else had experience with these or similar items? Just trying to gauge if my judgement is off base so I can re-adjust my attitude if needed, or try out a new yard.
