cpu hard drives

[tj1466]

hi can anyone let me no if there is any Platinum in CPU hard drives ??? thank you have a happy Thanksgiving to all

Very very little platinum. Better selling them as aluminum. Not worth the time, and effort to process for the tiny amount of platinum, and not all discs have platinum.

Most hard drive disks have a coating over the disk and the coating itself contains about 40% platinum but you would need 200 hard drives to yield enough platinum worth your time and effort.

How much platinum have you got out of 200 hard drives?

Can you verify this information?

Are any hard drive frames made of magnesium? I have bare frames that weigh very differently.

 

[Geo]

may be diecast.

 

[watcher6880]

Pretty sure it's diecast. The metal seems to be magnetic in nature so I am assuming that there is some steel base to it.

Do diecast frames have any value? I doubt there is any valuable metals in them. What do scrapyards pay for diecast?

less than aluminum. diecast is mainly a zinc alloy, people call it diecast aluminum but this is wrong.diecast aluminum is referred to as just cast aluminum but in different grades.diecast zinc is heavier and is dull gray until cut or scratched, other common names are "pot metal" and "pewter".a simple test to check for diecast is to scratch or cut a notch and spray a little white vinegar on it, if its aluminum there will be very little reaction but if its diecast zinc there will be a very strong reaction.

Hey Geo,
Thanks a lot for the information. I have heard of these different "metals" and often wondered how many people are throwing around a name which is basically incorrect. As it stands, I guess all my hard drive housings are pretty much worthless.

 

[Geo]

be sure to test. cast aluminum is bringing a decent price at the scrap yard.

bswartzwelder there are three categories you will want to separate your aluminum into: 1 sheet aluminum, 2 extruded, 3 cast. Extruded brings the most money per pound, then cast then sheet, unless it is aluminum siding which brings more. Most heat sinks are extruded, you look at the cut end head on and that is the shape of the die that the aluminum was forced through. Some heat sinks are just bent sheet aluminum though and you can see where it has been bent, it will be slightly rounded at the bend. Power supplies are a good example of this as they usually have them inside. Your eye will spot these differences easily after a while.

 

[bswartzwelder]

Again, thanks for sharing the knowledge. I did know about the three types of aluminum, but was unaware of the value of each. I would have thought sheet aluminum would have been worth more than cast aluminum, but I would have been mistaken. In addition to the aluminum siding, you missed one other type of aluminum. BEER CANS. Now that should have the highest value of all. LOL

i cant vouch for other states but good ol california, southern\
i thinl what the reference to sheet aluminum above is here called mlc or machined now they seperate it into
many catagories
1. painted---- mlc thats painted------49 cents
2. MLC------------------------------------51 cents
3. cast------------------------------------53 cents
4. painted 6063--painted extrusion---59 cents
5 6063 --clean extrusion---------------62 cents

understand there are others to Molybdenum -escalators-the part you stand on- usually less then mlc
diecast ----------------------------------24 cents

and as far as cans -people make the mistake at $2.20-$2.90 /lb (i do not do cans)but that's not only aluminum that's the crv
the state of california makes you pay when you purchase the drink

i dont know how experienced you are at scrap yards just a few pointers
t
2 words you dont want to here breakage and contaminated. when you hear this
kiss your values goodby. 4 cents to 15 cents
its very important to make sure you receive a 100% look in the eye when you ask what there paying
for such and such metal , you will find turning a way ,not answering ,suddenly being distracted. or just plain ignoring you
i have not found a yard that is even somewhat honest after 5 years and knowing almost everyone by first name
they still try one way or another
1 more thing if your stuff is not separated or completely clean of all foreign objects glue plaster paper plastic tape even stickers
dont expect top dollar
you could have a trashcan full of brass $1.87/lb and copper #2 $2.45/lb say 300 pounds and if not separated worth .04 cents a pound

just tryin to help with my 2 cents

Still waiting for an answer to this question.

@SMACK ....has gathered 2500+ .....he would be courios too.....40% of what?....
Total weight or from weight of platting ,which I undestand is below 20 microinches.....
