Copper is usually around 400, Silver is 429 and Aluminum is around 240-250.

I'm still a little nervous about this. I can't find an alloy of copper that is 310 W/(mK). China is notorious for fudging numbers. Is this from china?

Can you get an alloy from them? Or do you have an assurance that you can be refunded if this isn't copper?

I just hate to see a huge order of modules come in and turn out to be brass. Maybe I'm being over cautious here. Anyone else concerned or is the 310 number making everyone comfortable now?

Ok I've just gotten an aloy, it's C3600, it's a copper with aluminum alloy. If you find more accurate numbers I'll take yours. This can't be bad it's copper mixed with aluminum, mostly copper of course Still looks like it definetly won't be brass

And as for the money back if this ends up being non copper then they said theill refund it but I'm confident theill be copper

That's... not a copper alloy, as far as I know? o.o

If you meant C36000... that's bad news. That's brass, with a thermal conductivity of 115 W/(m-K).

Yup -.- I knew this may have been too good to be true. Make sure you are getting one of these three alloys: C10100, C11000, or C14500.

I don't think C60600 is going to be any better: for pure copper, you want the low 10000 series.

It looks like its going quick at this point. Copper or aluminum? as soon as I get enough interest I'll order them and they'll get to me in 15 days then I'll ship them to everyone. So depending how long it takes to fill up It can be as little as 20 days or 3 weeks, but it really depends

Well it sounds like we are getting real copper,

but ya 76 sounds fairly weak, alu would beat that,
asuming they dont use nock-off alu too

I'm glad I said something. If anyone wants to look up any info from Pontiacg5 (3.8mm thread). He had mentioned the alloy to me. Pure copper is harder to machine, and may thus be more expensive, if not for the higher costs of the material itself. Also check with Jayrob, I think his "copper" units may be an alloy as well.
