There is absolutely no reason to make a block out of aluminum since copper is not much more expensive. Furthermore, anybody that says that Al and Cu blocks work the same is wrong. Unless you screw up the test horribly, you will not be able to set up a test that gets you identical results. It is impossible.
It goes without saying that this also sets you up for the battery effect in the fluid.

...but if you paid attention to what Jaydee has been saying, copper is also much harder to mill, because of its higher density, so Jaydee has opted to stick with Aluminium, for now.
Perfectly commendable, if you ask me. There are many possibilities with Aluminium alone. At a flow rate of 200 gph and above, the temp diff you'll get between Alu and Cu is about 3 deg C.
