like the vanes on a windmill ... I assume is the reference.

Hey Nick, check this site out. Lots of cool magnesium wheels.

I email Fuchs yesterday and have just got this reply:

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.
Best regards Joachim Boehme

Ultimate tensile strength Rm 250 MPa

Elongation A5 8-10 %

Hardness 91 HB

physical properties

Density 2,7 g/cm³

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

Alleluyah!
Thanks Nick,
Now please close this thread and put this info in the main page...

Quote from my Fuchs contact

Dear Nick,
do you refer to the "FORUM.PELICANPARTS.COM"? A very funny discussion from our point of view.

I asked about the RSR double anodising finish too:
The finish is done by our subcontractor BOTHNER, I only now that they are using several stencils and that the painting is very expensive due to the "made by hand" method (spare parts).

Finally, an end to BS, and some good solid facts.

My Fuchs response looked like this....



He also went on to say he'd do a run of 16x11s just for Pelican at cost...... Just kidding.

[aseem]

I think its interesting that the Fuchs people has been following this discussion, and maybe are monitoring this board.

maybe they really care about the users of their products (and their products) long after the production has stopped.

[RickM]

I think it's cool as well. Would be nice if they continue to follow Pelican from now on. This is what I wrote to them yesterday.....

"Hi,

There is a debate currently going on as to the metallurgic makeup of
the infamous Fuchs wheel as used in the early Porsche 911. The question centers around whether the wheel is primarily composed of Magnesium or Aluminum.

Can anyone shed some light on this question? I'm sure you must have
Some Porsche fans there. :-)

Thanks for you time!"

Pleased about that but why pitting?

[Randy Webb]

Maybe Fuchs will come back into the (old) Porsche wheel business. If they could make those wheels that good 30+ years ago, what kind of strong, light wheel could they make with today's technology?

Of course, what we really need are light wt. brake rotors and tires -- those are the real wt. killers.

hmmm . . . is that how it is?
Here I though I had put an end to the BS, a few pages back.

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]

Therefore; the original assertion of this thread "Fuchs are predominantly Magnesium" is total BS.

Ya know, you'd think after 3820 posts that some respect might be due for you................ This place sucks.

Not sure why nobody wanted to buy that clip from Excellence? That rag sucks too.............

Humm, that's what I thought also. I quit paying attention till now.

Island, you have my deepest respect and admiration....yada, yada, yada

[island911]

Thanks guys.

I was just getting pissy about Waynes dismissive posts.
. . . the first was right after I first posted "and the answer is. . ." and got:

Anyway, good posts by Nick and Rick. 'Cuz now we know Excellence *can* get the numbers and facts straight. . .even though we all know Bruce Andersons market reports are all-askew. (tic)

Nah, nah nah nah nah....

Told ya so...told ya so....

hey, anyone still want to do the testing? I've now got a wheel that can be used!

That's what this board is for!
Its interesting to note Joachim at Fuchs appreciated this discussion.

Now getting to what started this in the beginning was Nick's question:
What about getting some Fuchs forged from Mg?

[mb911]

Be glad to test that for you and post results
