RE: [DML] Stainless in coolant system

["John Hervey" <john@xxxxxxxxxxxxxxxx>]

Tom, 
Everyone I talk to and deal with say that the brass radiators are the best.
Even the folks that make aluminum say it's the best but the problem is brass
copper are too heavy for race cars and with enough fans aluminum will last
thru the 1/4 mile and further on the high HP engines. I'm not saying it
can't be used, but even our SS over flow tank for some weight conscience
drivers say it's too heavy.  
As the engines have gotten smaller in the passenger cars enginering has
adapted to and designed in aluminum radiators. 
As a vendor concerned about pricing I have done a lot of talking and
investigation on aluminum radiator but as aluminum is going up almost just
as bad I don't know what we would be saving and what we would have to give
up in cooling to switch over.
I am working on the aluminum Rad's to see what happens.

This actually makes me think about brass or copper radiators. Very large 
surface area... What do the people advertising brass radiators say about 
this? Anyone?
I, myself prefer aluminum radiator anyway. It's lighter, cheaper and 
aluminum is actually better at transferring heat.
