How much copper is in MC/BX armored cable?
About 30% of its weight is recoverable copper. Here's what that means for stripping, grading, and what your yard will pay.
What MC/BX armored cable is
Also sold or searched as MC cable, BX, armored/greenfield cable. The armor dominates the weight. Estimate only — recovery varies with armor type; weigh armor separately if you break it down. Aluminum-armor MC pays extra for the armor.
How much copper is inside
The copper recovery rate is the share of a cable's total weight that is actual copper once the insulation and jacket are stripped away. For MC/BX armored cable that's about 30%, and typically anywhere from 25% to 35% depending on gauge, age, and condition.
In round numbers: 100 lb of MC/BX armored cable yields roughly 30 lb of bare copper. At an example #1 copper price of $3.90/lb that's about $117 of copper — but prices swing by region and by the week, so run it with the number your own yard pays.
Open the Copper Wire Yield calculator, pick "MC/BX armored cable (copper inside)" (or type your own recovery %), and enter your local prices to see the stripped-vs-as-is breakdown for your exact load.
Strip it or sell it as-is?
Verdict for MC/BX armored cable: not worth stripping — sell as-is by the pound. Stripping only pays when the gap between the bare-copper price and the as-is (insulated) price beats the time it takes — and that gap scales with the recovery rate. At 30%, there is too little copper — and too much fiddly insulation — for hand-stripping to be worth the hours. Sell it by the pound.

| THHN — heavy gauge (4 AWG to 4/0) | ~84% | 80–90% |
| THHN — standard (8–16 AWG) | ~80% | 75–88% |
| Double-insulated power wire | ~75% | 70–80% |
| Romex / NM-B (indoor solid) | ~65% | 62–70% |
| Mixed #2 insulated wire | ~60% | 55–69% |
| AC / appliance whip wire | ~55% | 50–60% |
| Extension cords / SJ cord | ~42% | 35–48% |
| Cat5/Cat6 — solid bulk runs | ~42% | 35–50% |

Recovery figures are cross-checked against at least two published yard references and kept at the conservative end of each range, so surprises land in your favor. Measuring a stripped sample of your own cable always beats a table.
MC/BX armored cable: quick answers
How much copper is in MC/BX armored cable?
About 30% of its weight — usually 25–35% depending on gauge and condition. So 100 lb of MC/BX armored cable yields roughly 30 lb of bare copper once stripped.
Is MC/BX armored cable worth stripping?
Not worth stripping — sell as-is by the pound. At a ~30% recovery rate, stripping rarely beats just selling it as-is by the pound. Run your own prices through the Strip or Sell calculator to be sure.
What copper grade does MC/BX armored cable sell as?
As-is at most yards; armor is steel or aluminum. Yards buy insulated wire as-is at a discounted "ICW" rate that already assumes an average recovery; stripping clean copper moves it up to a higher-paying bare-copper grade.
