If you are asking about the aluminum strip just underneath the armour, it is for sheath bonding as it has a shorter distance from end to end than that of the spiral that makes up the armour covering.
In older types of armored cable a aluminum strip was used as a bonding medium. This strip was wound back over the outside of the sheath and the connector on the end of the cable was used to secure it. Test were made to see how much short circuit current could be handled by this type of installation and it failed usually by burning open and leaving no ground at all. Now all armored cable has a separate, usually bare copper wire, embedded in with the current carrying conductors. This ground wire is now terminated onto a lug found in the junction box or on the device the cable is connected to.
The bare copper conductor found in non metallic sheathed cable is the ground wire. On a wire count in a cable set the ground wire is never counted even though it is always there.
It would be green or bare. That's if you have a grounding wire in the cable. You may not have one.
Instant surface rust, much like bare aluminum gets oxydized immidiately.
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.

Bare cable is simply a conductor without a coating, sheating, or covering. It is just bare wire.

Speaker cable can be used bare or with pin, banana, spade or ring terminals.
The colours will be, black, white and a bare copper ground.
if an atom is deprived of all its extra nuclear electrons orbiting around the nucleus then it is referred as bare nucleus. from google
Aluminum siding would be slightly noisier. Some of the cons of aluminum siding include scratching and denting. Aluminum siding is easy to scratch, which reveals the bare aluminum beneath the surface. It is also easily dented by small objects such as stones or hail.
The wire conductor colors in a non metallic sheathed cable are black, red, white, and a bare copper.
You can stand on bare ground tile or any other conductors (water, aluminum, etc.)
Prices vary based upon grade (wire, sheet, litho) as well as quantity mixed aluminum is around 45 cents per lb Bare Aluminum Wire is approximately $1.15 per lb
for example, a non profit organization is when you are raising money and you get to your bare minimum goal...there is no extra money
Around 200 lbs. Depending on block material and block type. Aluminum blocks are around 100lbs.
