You asked for it, so here it is.
Aluminum isn’t as durable as copper in certain applications.
Oh, by the way...which type-grade of aluminum? Which type-grade of copper?
What are the block guys milling? I bet the easiest (softest AL) and then anodizing a harder coating onto it.
Swiftech is doing aluminum because they are comfortable (at this point in time) with the economics of these pieces. If they find in 6 months that chunks of corrosion start showing up in computer water cooler lines across the states they will assess the situation and take action.
I had an old non-anodized AL block that worked great for a year or so, and then it started to show corrosion. All efforts taken were ultimately in vain and a new block milled from 6061 was used as a replacement. As a study I checked it every month or so and the first place it started to corrode was in an area where the surface was marred, where the threads had been cut and were not protected (sealed) by the fitting. I used to work in the after market auto industry..there are many types of AL. Anodizing can take on another mind-boggling discussion.
