A couple responses mentioned that the steel may last only a few years.
I mentioned that I have read of using electric fence wire only to
suggest it as an inexpensive alternative to copper.
I suspect, and will wait to hear from the experts, that the ph of the
soil affects the live of any wire. In particular, I expect acidic soil
will attack steel and alkaline soil will attack aluminum.
My soil ph is about 6.8-6.9 and I've not detected any appreciable
deterioration of either copper or aluminum on top of that soil after 8
years. Steel rusts if left in that soil. I've not tried any fence
wire, galvanized or otherwise, in contact with the soil and won't guess
how long it might last.
Steel wire is stronger than aluminum wire of the same size.
I'd like to hear the experiences of those who have tried various
materials, and if, possible, a report of the soil conditions on which or
in which the wire was placed.
