Armor Cable or AC- Thought it might be helpful for a little explanation on types of Armor Cable used for electrical wiring. Often just called BX or (armor clad, flexible metal conduit, AC, AFC, HFC, MC and more) that has individual insulated wire conductors with the metal "sheathing" providing protection to the wire conductors. People will call all armor cable "BX", when actually there are different types of armor cable, BX is a brand name or trademark just like "Romex".
BX - has a bonding strip integrated into of sheathing metal (starting in 1959) to allow the casing to be grounded. There is no ground wire.
MC - has a individual ground wire and the casing is not grounded.
HFC - has both a individual ground wire and a copper bonding strip in sheathing.
AC - has "paper" covering surrounding the insulated wire conductors and will have a bonding strip.
AC cable can have steel or aluminum used as the armor sheathing. With 12 or 14 AWG insulated copper wire being the most common wire gauges used. With one or more "hot" wires, one neutral and a ground wire (insulated or noninsulated).
If you have just a small amount of AC cable to scrap out I would use a cutting tool (your choice), cut the cable into manageable (safe) lengths (3 to 4 feet long). Remove the copper conductor wires, strip the insulation to get bare bright copper. If the metal sheathing has a copper bonding wire, you can also remove that as well and sell as #1 copper. If steel clad is used goes into shred bucket or aluminum clad in "aluminum" bucket (depends on yard classifications). You could have 2 or 3 types of
scrap metal to sell (make the most with the time you can spend, with very little effort).
If you have a lot of AC cable (100,000 pounds is a lot), sell to scrap yard or wire broker as is. Take the money and move on to next bigger and better scrap adventure!
