Rather thick gold plating on aluminum

[nickvc]

Forgot to add that I stripped them with dilute nitric acid.

Greetings Geo ... do you think dilute nitric would remove HDD platter foil ??? I mean the discs are said to be aluminum inside.....

Waste of chemicals and your time, use them as bird scarers or bin them.

The precious metals on HDD platters are locked in a polymer compound. Acids can not reach the metal.
