Casting Aluminum over copper tubes 2

[tinsnano]

Dear All,
I have a project involving casting aluminum block where copper tubes are embedded. Unfortunately i found in the internet that liquid aluminum dissolve copper. My aluminum block is 30cmx30cmx6.5cm and Refrigerator copper 12mm OD. But again in the internet discussion i found some one saying what if we pre saturate the liquid aluminum with copper will it dissolve additional copper? what do you guys think. if his idea is right then how much kg of copper should i dissolve in 11 kg of liquid aluminum?

Thank you tbuelna.
It seems most the forum members believe there would be no enough time for the copper tube consumed by the aluminum, so i will proceed with the project

but what is you opinion for per-saturating the aluminum with copper?

Pre-saturation is a waste of time as there is no real problem here. A moist mold will definitely cause problems.
