how does that have anything to do with corrosion?

if the nano particles are a form of Cu+ suspended, it would eat into the ALU and hence the coolant would cause corrosion.

Im trying to work out all the fine points on your coolant b4 i give it a test. So sorry if i sound a bit curious.

What got me thinkn this is how it reacts to copper, it seems the solution is safe and has no effect on copper, however how would the solution handle alu? Or even better, how would it handle a mixed loop scenario since we still cant get people to NOT USE ALU.

Once again sorry if i sound a bit curious, im really interested in your solution.
