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.
For a 100 amp sub panel, you would typically need a 2-2-2-4 aluminum SER cable. This cable consists of three insulated conductors (two hot and one neutral) and one bare ground wire. It is important to always consult your local electrical code and a qualified electrician to ensure you have the correct size and type of cable for your specific installation.
The bare copper conductor in non-metallic sheathed cable serves as the grounding conductor. It is designed to safely carry and redirect any electrical faults or leaks to the earth to prevent electric shock or fires. This conductor is uninsulated to facilitate conductivity and grounding capabilities.
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
Do not use this type of cable to feed a 120/240V dryer outlet. The outlet is ungrounded, and the third conductor is neutral not ground. Your ground wire must be sheathed by code. You cannot use the bare neutral conductor as ground. Diagram Did Not Come Through. You Have a 3 Prong Connector. The Prong On The Bottom By Its Self Connect The Bare Wire. That Is What Was # 3 Connect The Others To The Two Prongs Next To Each Other. Hope This Makes Some Sense (1) (2) (3) Connect White To (1), Connect Black To (2) Bare (3) Good Luck

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.
The wire conductor colors in a non metallic sheathed cable are black, red, white, and a bare copper.
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.
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.
