The subject says it all.
Has anyone located any upocc wire that can be used for tonearm rewiring?
Thanks.

I have found upocc headshell wiring from "phono 1877" but no upocc tonearm stuff.
I'm guessing that they either don't make super small gauges or put in flexible insulation, but UPOCC was designed for miniaturization -- there should be plenty of light gauge wire.... Hmmm, maybe just not braided litz?

From what I understand, the lowered number of crystal boundaries makes it a less noisy conductor, which can be important in some miniaturized circuits.
The only noise to speak of would be the thermal noise of the wire itself due to its resistance. The only "research" I've seen on OCC wire indicates that it's about 1% less resistive than plain copper wire.
So if it's noise you're worried about, you could just use silver which at about 6% less resistance than plain copper wire would actually beat out the OCC.

What is your source for the claim that OCC is particularly useful for miniaturized circuits if I might ask?

I read about it here. It does not seem like heavy duty marketting, else you would've heard about it by now.

Sure, the article is marketting.
Does that mean OCC is useless or that there was no use for OCC in miniaturization?

I've not heard of it being used in miniaturization. Doesn't mean it hasn't been, but I've not heard of it.
While ultimately it does result in fewer grains, it's primarily a casting process to allow for the casting of very fine wires and foils. But as far as wire goes, they seem to be able to draw copper down to 50 gauge and lower without using OCC copper.

The info in the marketting says that OCC was developed a long time ago. Apparently, there was some problem that it tried to solve, else why bother?
While I'm sure that smaller gauges of OCC copper wire are available, I can't locate any for sale.
OTOH, OCC Silver is available in light gauge and seems to be used in the place of copper, for tonearm cables.
Why? I don't know. I too am not an expert in this field.
What I do know, is that I really enjoy the results of using OCC copper in interconnects and hookup wire.
A previous experience with silver/gold wire has turned me off it, hence the search for UPOCC copper.

The problem that was being addressed was "blowout" while continuously casting fine wires and foils. Again, there's not one word mentioned in Ohno's patents regarding the electrical behavior of the wires.
And at the end of the day, that's really all that matters.

I first stumbled upon this thread a few weeks ago but was on vacation so I did not have a chance to reply.
The source of the information is the Preface to the English Edition of Dr. Atsumi Ohno's definitive book on casting, Solidification - The Separation Theory and its Practical Applications.

It is totally understandable that Steve Eddy missed this since he probably only read the original Japanese edition of the book, 😉.
