Some aluminum server shelves, and a big 6' section of ~2.5" copper pipe...
Some aluminum from motor casings and espresso machine mechanisms...
Brass: espresso machine fittings, boiler shells, and a can of house keys...
Insulated wire from miscellaneous appliances...
Bare copper: some pipe fittings, and wire from motor armatures...
This is a funky place in a funky part of town. They have huge (beat up ) bins like this for your stuff. They mostly serve larger recyclers -- the guy ahead of me had a cart full of brass plumbing fittings.
Provide ID, license plate number and fingerprints at the cigarette-smelling window...
Net result: $58, not bad for a 10 minute drive. Obviously, copper is where the money is. Stainless only got me 20 cents a pound -- surprising, considering how expensive stainless is. Any commercial kitchen contains thousands of dollars worth of stainless equipment.
Interestingly, beverage can recyclers pay about $1.30 for aluminum cans. Scrap aluminium gets you $0.25.
When I retire, I'll set up a workstation in my garage, and make a hobby out of collecting motors and stripping the wire out of the armatures.
