I used to see a lot of brass caps with brass tubes and copper fins but
I don't think I've ever seen copper tubes, much less end caps and I
haven't paid much attention lately but the las brass/brass radiator I
repaired had brazed foil to the tubes,

For sure I have seen copper fins, but they radiate better than aluminum,
so changing them is a down grade.

I was thinking the tank and tubes when I made my comment.

Diamond conducts heat well??? How about that! Well, it *is* carbon. I
just never would have thought of diamond as a good heat conductor. Talk
about an expensive radiator!

Check with a computer chip geek, is used there for the excellent
thermal conductivity.

It's lightweight, relatively inexpensive, easy to machine, weld,
extrude, and form, and an especially good heat conductor, Josh.

Because weight savings are a good thing. The lighter your vehicle the
less energy needed to move it, whether on flat roads, or stuck in
(guffaw) deep mud!

> Is aluminum an especially good heat conductor or something?

Why, yes, Joshua, it certainly is. Its thermal conductivity is rather
efficient. More so than steel. Do you have a piece of aluminum stock and
a sander? Sand the aluminum and grind a hell of a lot of material off.
Gets kind of hot in your hand, doesn't it?
