Question for mete?

[Fox]

mete, I may have a line on some heavy copper plates for quenching. I was wondering what the heat dissipation rate of copper is compared to aluminum? Thanks.

The thermal conductivity of Al is about 62% of that of Cu.

In other words, Copper is half again as fast as Al. Go for it. The main reason I went with Al is cost. Al is much cheaper than Cu.

These values are for pure metals. Values of pure Cu against 6061 Al which I use, show the Cu to be twice as conductive.

That's right, thermal conductivity for Al is .53 and for Cu .94. So depending on price make your choice.You should use plates 3/4" -1" thick.

Thank you, gentlemen.
