You must deal with freon (proper) now if you gut the fridge you will also find a AL cooling radiator & a little copper fan motor , Some fridges are a gold mine, some are cheap. But for all items you have it's up to you as to the detail you take apart. As all the items have - copper - brass - AL - steel - wire. The quantity of of the different metals has to do with the quality of units. The fridge compressors have decent value, as is (.03 above short ) getting the copper out is work unless you have equipment, and the will to do it.
I have seen washers with heavy steel gear boxes & washers with the motor and a belt and pulley system.
