Copper is compatable with about almost anything but acid.  The big problem
with copper tubing is that it may flake of small bits of copper from the
manufacturing process that may plug up jets and stuff. Also copper is soft
and may damage or fatigue easily when exposed to vibration or foreign
objects, ie a rock.
