Keep the potential difference low, and it'll last much longer.
Nickel to copper -=> 0.05 very good.
chrome to copper -=> 0.25 mid-range, but should be good enough for this application.
Aluminium to copper -=> 0.40 bad

I understand how the nickel and chrome works to reduce galvanic difference but difference between aluminum > gold is .75 so difference is much higher. Gold > nickel is .35 and nickel >copper is very very small.
I'm surprised that block had lower pressure drop than mcw-60 but i'm not surprised it outperformed it and all the other blocks with that design. Not surprised with alphacooling being restrictiveness but DAMN!:
