Stainless steel

[Imran]

Does anyone know where in computers is stainless steel. I only know it is in hard drive, is it anywhere else?
BTW: Great forum

I doubt there is a need for stainless steel in computers
unless they are for outdoors usage or for usage in harsh environments.

Aluminum is used in the hard drive cases probably for radiating
heat away from the drive out into the case. I doubt the hard
drives are made of stainless steel as they seem way too light
to me to be made of steel.

Not whole hdd. Only small mount where magnets are is from SS.

I think some of the hard drive covers are stainless steel. Some of the rods inside of the floppy/CD drives are stainless also. If it is too heavy to be aluminum and it is NOT magnetic, there is a good chance it is stainless steel. Some stainless steel is slightly magnetic but you can tell the difference.

also some earlier drives have SS covers quantum's i believe.

Thank you everyone, your help is really appreciated. Is there any pure tin? I know that most solders are 40% tin, but I dont know how to separate tin from lead. I need it to make stannous chloride.

just use some lead free solder would be ur best bet

Ok, but how do I recognize them?

It will say lead free. It should be about 95% tin and a little antimony.

What about in old computers? Is pure tin there?

I can't remember which make harddrives (10G,20G & 40G) had stainless steel covers, you have to be careful though, sometimes their is a steel plate glued/stuck to the stainless cover, check both with a magnet. The base are usually aluminium, stainless screws in places.

Keep the reader heads as some contain PM's. Their are some very small gold plated pins that are imbeded in the reading arm, connecting some of the electrics.

Oh and don't forget the older disc's may have PM's as a surface plate, which makes me wonder if a modified CD cleaner/buffer could be used to take off this coating, using sandpaper intead of the cloth buffing wheels??

If in dought keep it and store it, lost count of things I have tossed, to only realise later (months - years) that their was some value in them. :roll:

Right Deano, I'm waiting for someone to tell me about the pounds of Platinum, Gold, and Silver I have threw away in the 3.5 floppy drive heads....
