Don't have time to go through everything right now.
Even if the question ahs been ask before, could you tell me if another matel can be used instead of copper?
All the examples I have seen on the web have shown copper being used and I would like to know if other "non-ferrous " metals would also work, since
this could effect the cost.

Copper is a the 2nd most electrically conductive metal
while SILVER is the MOST conductive but that is rather
expensive.
Aluminum Oxide Ceramic Infused with conductive
or non-conductive (i.e. always-touching/criss-crossing)
fibres can be used as a replacement for the linings
in exhaust nozzles or as coverings for ultra-heat
resistant turbine/fan blades or as the lining in
combustion chambers.
Alumina (aka Aluminum Oxide) is ultra hard
and can have it's ceramic-like brittleness
compensated for by adding small metallic
or non-metallic fibres to increase tensile
and torsional strength. It ALREADY has
high compressive strength and high
heat resistance (i.e. high melting point)
at 1500 Celcius (2700F) to 4000+ Celcius (7200F)
depending upon the ceramic formulation.
The 7200 Degrees Fahrenheit formulation
is a rather esoteric one that uses exotic
rare earths and other corrundum-like materials.
On a rather INEXPENSIVE basis you CAN get versions
of Alumina to width stand 2000 DEGREES CELCIUS
pretty easily and consistently!
If you need subsitutes for Copper as a conductive material
such as when collecting and transporting electrons ;-)
in a desired manner, then try softer formulations
of aluminum metal or if you need material flexibility
(i.e. bend, twist and coil) then use a high-salinity
liquid (i.e. Salt-Water!) encased in heat-resistant
non-conductive hoses.
If you're making saucer-like aerospace vehicles
that use Electro-Magnetic-Plasmadynamic
principles of flight, then you're going to have
to sandwich conductive layers of magnesium,
bismuth and some titanium interspersed between
Polyethylene and/or other semi-and-non-conductive
separators to make a dialectric hull (basically make
a giant supercapacitor!) that can be charged and
discharged very quickly (technically a transcapacitor!)
This is so you can push the Earth's atmosphere
out of the way (i.e. Plasma Sheathing!)
;-) :-)
Then to do Gravitational Shielding
so you can actually FLY your non-aerodynamically
shaped metal bucket, you're going to need a
REALLY HEAVY element such as vaporized
Tungsten, Lead, Gold, Uranium and you're
going to need to encase the chosen heavy
element in a Torus (i.e. large metal hose
all curled up -- See search term: Tokamak)
and accelerate them to near relativistic
speeds using a set of pulsed linear
induction coils.
The magnetic field created by the pulsed coils
will CONFINE the highly pressurized spinning
plasmas you will be creating. The reason why
you use magnetic confinement is that not
only is that plasma REALLY HOT, it's ALSO
that you need to make MANY micro-vortices
at near Planck's-Length scales so that
gravitational waves cannot pass through
or between the atomic structure of the
spinning heavy elements.
This is NOT a molelular scale process but rather
a Planck's Length (i.e. Quark-scale) process to
use spinning balls of highly excited atomic
structure to exert one or more of the
nuclear forces (i am assuming is the
STRONG binding force) so that as
those spinning/orbiting balls of
matter BLOCK as many directions
and pathways as possible so that
the WEAK FORCE (i.e. Gravity) CANNOT
pass through the gravitational shield structure.
This means anything INSIDE the torus's diameter is protected
from gravity and the accompanying issue of INERTIA being
applied to persons or objects inside the specific vertical
or horizontal AXIS that the torus structure encases.
You may need a GLOBULAR structure containing MANY
LAYERS of accelerated plasma if you want to protect
yourself in ALL directions from gravity and inertia!

I hope my explanation helps inform you
that YES Copper is NOT totally necessary
to build conductive systems and/or
aerospace vehicles.
There are OTHER materials available,
but you need some serious money
tomanufcature and machine such
more-exotic materials.
I HOPE THIS HELPS!
