What alloy?
 

All,

Does anyone know the aluminum alloy used by Fuchs? I need to give a potential anodizing source some details to determine their suitability...

TIA,

Chris

They are Magnesium, not aluminum. If your potential annodizing source didn't know they were Magnesium, consider Al Reed refinishing. I tried several places in Atlanta that turned the work down at any price.

do a search using "Al Reed". He is far cheaper than any of the local shops I talked to and does excellent, consistant work.

Sorry -

didn't notice you are a senior member.

I'm sure the reference to aluminum was a mistake. And you are aware of Al Reed and how the search button works.

I'll stop typing now...

Fuchs are magnesium? Don't think so.

OOPS, guess that answers my question... I swear it didn't come up in my search...

Steveinatlanta,

Don't sweat it. Sometimes we all miss things.

So?..... this ( the Fuchs) is still an aluminum alloy wheel...what does a fraction of 1% Mg have to do with calling this a magnesium wheel?...

Now the 5.5 x 15.... " gas burner" wheel....that's another story....

ALUMINUM...

Not true. Years ago, Pelicanite Nick Moss contacted Fuchs directly for an answer to this question.

Q: Can you tell me what aluminium alloy was used in the Fuchs Porsche rims of the 60s and 70s?

A: We used 6082(USA), 3.2315(DIN), AlMgSi1(Type) or FUCHS Designation AS10.62,
.62 indicates Temper Disignation.

EN AW-6082, 3.2315

typical mechanical properties

0,2% Yield strength Rp 0,2 240-310 MPa

Ultimate tensile strength Rm 250 MPa

Elongation A5 8-10 %

Hardness 91 HB

physical properties

Density 2,7 g/cm�

good welding properties

very good anticorrosion properties

good anodizing properties

good drilling and turning properties

alloy: AlSiMgMn (former AlMgSi1)
Temper: T651 stress relieved by stretching ,heat-treatable

Composition %: Al 96.5, Mg > 0.64, Si > 0.7

There is an indepth thread on the subject here

Excellence article on Fuchs, (issue#93 pg 107) says the alloy used to make Fuchs is "AlMgSil or AA6082."

AA6082 is; Al 0.9Mg 1.0Si 0.7Mn

--OR--
0.9% Mg (Magnesium)
1.0% Si (Silicon)
0.7% Mn (Maganese)
97.4% Al (Aluminum) [implied balance]


Slightly different from Jacks of Nicks of Joachims factory info.

For yet another data point . . . and a bit more detail;

Wow,

And here I thought I was the only one who went to matweb.com for entertainment.

You guys had better stop all this talk before I get too excited. What comes next is a downward spiral about the drawbacks of adding sulfur to improve machinability...

:eek:

Chris

And the lug nuts while we're at it?

Sherwood

911pcars,

You don't sound very excited... Are you patronizing us?

:rolleyes:


Chris

?"You don't sound very excited... Are you patronizing us?"

Chris,
Not altogether. Half mocking ourselves, half-serious in that this data is both informational and related and should be in one thread.

My next question is about its half-life in anticipation of the next poster.

Sherwood

Half-life!

Now you're speaking my language.

It's just the natural log of 2, divided by the effective attention decay constant!

Chris

Chris,
See. I told you.

Sherwood

I'm going back to lurking...

No, stick around.

You've only got 65 posts. Of my nearly 3,000 I must have at least 100 (or more :() where I ended up puting my shoe in my mouth! SmileWavy

We all learned something.

Now imagine my embarassment with less than 200 posts - I'm hoping to get the dumbest stuff out of the way early.

P.S. - There are quite a LARGE number of very well educated and diverse contributors on this board. Post prudently, state your opinions as such, and ask questions. You and your ball should really consider staying...
