Sorry I was weighing corrosion resistance and density.
I was thinking condenser fins on cars and not electrical circuits/plumbing.
It would be good if not connected to copper (so plastic pumps are ideal)
I found this to be interesting:

Copper is both more expensive and a better conductor. Second only to Silver.

copper is 3-6x more expensive than aluminum...
And copper is one of the best conductors, that why they use it for electricity, and heating elements. The best conductor is gold, but that's to expensive to use.

or is aluminum conduit just more expensive than copper due to manufacturing issues? I'm just curious.

|mistergreen||Yes, saltwater and acidic water will corrode the copper but safe for fairly neutral freshwater. Nor worries for those SSS shrimps.|

|AVN||Meant to say that I agreed, and realized I was only referring to the oxidation that occurred between salt water and copper pipes. Freshwater and copper obviously has no ill effects, so long as the minerals in the water don't react over time with copper.|

I used to manage the thousand gallon public aquarium at my community college campus (OCC) and we deal mainly with saltwater.
Copper is forbidden for any piping in our building because we've had mass die-offs when we unknowingly put copper piping in our automatic top-off system.
So much hated is this metal that when the building was first built and designed, one marine biologist Professor Dennis Kelly decided to stand by and watch them install all the copper piping for the building before telling them that it was in their contract to avoid metals like copper. Needless to say they had to redo all the piping and we had to hear about it during class.
Then came a huge lecture about what to use and what not to do when it comes to system water. You won't begin to believe the amount of [censored][censored][censored][censored] you're not allowed to use in the water.

|longbeach||My house was built in the 50's.... copper pipes....never have had a problem. Keeping OEBT's, TT's, CRS, CBS and mischlings all is and has been ok. I think new copper pipes need to "age". Anyway I would worry about copper except in new pipes or hardware.|

Try aluminum conduit, aluminum oxide doesn't scale off like copper's.
Aluminum is actually the best conductor, copper is the cheapest conductor.

|HD Blazingwolf||im all copper as well, so is my water heater fish and shrimp are fine, algae doesn't die on water change day either|

Friendly reminder that water that flows through copper pipes has the potential to wipe out shrimp/sensitive fish ecosystems.
Doesn't matter what copper it is, if it's oxidized or what. It will leach trace elements into the water which will then kill off your entire tank of Grade SSS Red Crystal Shrimp.
Oh the horror stories...
