Strange colored casings

[BackFromDC]

Can any reloading sages of INGO help a newb out. I was given a giant bucket of casings from a friend, and after tumbling them I got a few that are weirdly colored. Can anyone ID?

Brass .30-06 on the bottom right for reference. I was able to determine that the .380 on the bottom left is some sort of steel case. The others don't stick to a magnet or clean up after brasso.

Alien technology?

The .380 looks copper washed. Cut one of the others in half. I'd bet it's severely tarnished brass.

Soak one in vinegar, it will take the tarnish off

Could be tarnished nickel too. Hard to tell from the pic on my phone.

Those look like steel .223 cases. the others could be aluminum if the magnet doesn't stick to them. I wouldn't try to reload anything that isn't brass. Some steel case 9 mm cases are plated with brass and WILL go into a resizing die, but they can get stuck. The headstamp on those are OZK, just pitch them if you run across them. The Chinese copper washed their ammo casings that were metal for better feeding. More scrap metal there.

UPDATE! They're now pinkish...

Thanks for the suggestion on soaking them in vinegar!
