View Full Version : Aluminum or Copper?
Is there a great difference in temps between a solid copper container and an aluminum one? :)

The difference is mainly when dealing with loaded temps and with the X2 kicking out a fair bit of heat then i'd go for copper if you get the chance

Well, the chance is all money... :D So we'll see. :)

Aluminum is good if you can't afford copper but it kind of sucks at high loads. A properly designed solid alumi unit will hold a load fine, my units hold -61c and -66c but a copper would hold the load closer to the idle. My units idle -70 and -73c. The 2.25" and 3" mousepots that is.

thate is nice to know , thane i will go for copper has well :D
are the temperatures overall that much lower with copper, or is the main benefit in the idle-load variation?

Some people say that with cryo temps you achieve more load then copper.. to bad this isnt tested "on our oc world"
so theres a series of decisions based on common sense and probability, but no real testing done? Surely someones had a fun day of checking the differences?? :)

Well if you could make solid units to test ;) Its allmost a no job to do that and test every unit we make.
LOL I cant afford both, so buying a tube of any kind will be an achievement.
My wallet says alu tube, but if the temperature differences are that big, my head says copper. May as well buy quality if it`ll benefit the clocks.

Kenny you could use the Team UK tube if you want for cheapness aslong as its ok with SoddemFX :)
Doh! yea I forgot about that! LOL Highlander has a similar idea, wont say any more its up to him to say as much as he wants. Might ask Soddem for a loan an see how I get on. Been thinking of moving to DI over my Mach for lower temps so would prob wanna buy one eventually. Will ask him. Cheers!
:D

Ok i've got the Team UK one atm but can easily send it you.
You could use my gpu tube aswell if you wanted to use that
ok. I`ll see about sourcing DI for a couple weekends time and let ya know? Is that ok?
Cheers! :D:D

Aye if you want to add me to MSN or something it might be in my profile i might be able to give you a few numbers :)

* diamant: 1000 - 2600 W/mK
* silver : 429 W/mK
* Copper : 385 W/mK
* gold: 320 W/mK
* aluminium: 229 W/mK (205?)
* platina: 70 W/mK
* steell: 42,9 W/mK
* lood: 34,7 W/mK
* kwik: 8,3 W/mK
* kwarts: 8 W/mK
* ice: 1,6 W/mK
* glas: 0,8 W/mK
* wood: 0,04 Ã:banana: 0,12 W/mK
* asbest: 0,09 W/mK
* aërogel: ca 0.017 W/mK
higher is better in our case and the difference is big ;)
Esto es correcto a 25°C. Cuando baja la temperatura la conductividad termica de los materiales sube.

Es importante destacar ademas que no solo el material interviene en la temperatura final del sistema, pues importa mucho el diseño termico y la superficie de contacto entre el fluido y el tubo. La superficie de contacto es lo que mas ayuda a transferir el calor, y es por esto que los disipadores tienen aletas unidas a una base.
Estas aletas ademas deben tener una relacion entre el espesor y la altura que dependera de la capacidad del fluido para absorber el calor y de las condiciones de agitacion (turbulencia) de este mismo. Tambien tiene que ver con la cantidad de refrigerante que viaje a travez de las aletas.
De este modo, el material es solo un factor secundario en la construccion de un tubo para hielo seco o para nitrogeno liquido. Importa mucho mas su superficie de contacto, la forma de las aletas, el espesor de la base y la distancia maxima entre aletas y foco de calor. Esto se puede lograr conmayor exito en un tubo de 2 piezas. Hay buenas tecnicas para soldar cobre y aluminio sin que la soldadura quede debil o que se pueda quebrar con el frio

Now, I' m Projected my first Container in ALUMINIU to DRY ICE.
