Hi there, all,
(especially those experienced in home foundrywork)
I've accumulated quite a lot of computer hard drives and have been 'processing' them ready for offering them to my local scrap metal dealer.
The actual disks (aka 'platters') are aluminium alloy but coated with the magnetic material that actually stores the 0s and 1s. As far as I know that coating is very thin so its effect on the weight is negligible.
What experience have Modders had with melting such HD platters? Does the magnetic coating cause any problems?
Can I, with a clear conscience, include these platters with the rest of my scrap aluminium offering on the basis that the coating is chemically benign?
