Not so!
This method only applies to surface type corrosion materials that when
formed protects against ingrained corrosion.
Aluminum and copper are types where corrosion is halted after surface
corrosion. Anybody who has had an old car knows that rust can travel under
so called protective surfaces
This analysis was used with succes in court in the case of using aluminum
wiring in stead of copper wiring. The vital point was
that both of these materials formed a protective corrosion coating
that could not be undermined if the inter pressure point was not open to
corrosion penetration.

Just get a good clamp out of steel or copper and really torque it so you
get
good contact. Good contact means there's metal-to-metal with no space for
air or water. Not all strands will get this molecular contact but most
touching will. Make sure the clamp is a cheap pot metal one as it'll
corrode and fall off if it doesn't break while your torquing it. If you
hve
any Thermit, it'll make a better joint.

The answer must be here but after some searching I can't find it.
There is all sorts of conversation about ground rods and dissimilar
metals but I can't find the basic answer I need -- How do you make the
steel to copper connection? Do you simply clamp galvanized steel to
copper? Thanks.
