Most metals in common use are recyclable. Whether they actually are recycled or not probably depends on what they're attached to. A washing machine, for example, contains plastic and rubber, and those have to be separated from the metal for the latter to be recycled. Perhaps someone can comment on that.

Copper is of course valuable enough that at times people have stolen copper wiring to sell it for recycling. I don't know whether that's a thing today.

At one point, printed circuit boards contained gold--used, as I understand it, to coat traces (sort of like wires) to prevent corrosion. Tiny amounts, of course, but apparently enough to warrant recycling. I actually knew someone who stripped the traces off of old boards and sold them. Again, I don't know whether that's still a thing.
