Hard drive platter

[Barren Realms 007]

I need some help identifying what might be in this hard drive platter please. It came out of an old hard drive I disassembled the other day. I'm curious to know what it might have in it so I will know what avenue I might take in processing it.

I tried to upload picture but it is to big in size and program won't accept it.

Here is the info on the cover of the drive.

The platter is copper in color with a silver color about 3/8" wide where it mounts to the drive. It is about 5-1/4" in Dia. It has a silver streak running thru the center if you look at the edge.

I know this is not much info and I might not get a reply till I can resize the picture. Thanks in advance.

It's likely an Aluminum disk with a ferric oxide coating.

Sell it as aluminum scrap.

BTW here is a picture of the platter. Looks like there might be copper in there.

Yep, ferric (iron) oxide coated aluminum. It's basically high grade rust, which is why it has that reddish color similar to copper. I really doubt there's any copper in there though.
