Separating Grades?

When I grinded into it with a bench grinder it did not show red/orange. The bolts were non-magnetic so I figured they are aluminum as well

Alright numbers are in, I went to AKS recycling which I believe is the best yard around Fitchburg MA.

They took literally all my wire as #2 copper even though I'm pretty sure a lot of it was not varnished @ $2.00/lb and all the plumbing copper (as long is there was no paint on it) was taken as #1 copper @ $2.20/lb

I had a mix of white & yellow brass but they took it all as the same class @ $1.40/lb

My aluminum was both sheet and cast but they only take that as one class as well @ $0.40/lb

I had some non-magnetic stainless and they bought that @ $0.35/lb

I brought 180lbs of light iron and I got $14 so that's still at least $0.07/lb

I have a bunch of steel and iron left to bring, but need to get the sorting understood. Seems there are two iron types; light and heavy. Is steel only considered a single class? Or is heavy iron considered steel??

The outer silverish layer is softer than the copper, when you hit it with the grinder, it ground off some of the copper metal & at the same time, smeared the silvery tin (or nickle) over the copper face & that made it look silvery again.

The bolts were stainless steel. Because of how they look I think theres a 'steampunk' interested in them somewhere.

You lost some easy $$ there, not much, but easy $.

Bugger.
