Before thinking about hard disk platters, try learning the use of the internet.

There is such a wonderful site that will answer nearly all questions asked, it it here or even here.

Ultimatly it may bring you out here.

Which bit of the hard drive do you mean?
The frame is aluminium, the lid is steel, the platers are as linked above, some bits are plastic, FR4, silicone etc.

Merry Christmas.
