Re: Ampco: Good material for water block?
much lower thermal conductivity than copper seems like a good reason for me.
It is the same as the AL trade off without the goop problems; for want of a better word. Easier machining vs better thermal conductivity and hence performance. I would think on a modern block solid thermal conductivity is important enough to warrant the use of copper.
A copper alloy is unlikily to be as thermally conductive as pure copper.
