1. Introduction
In the past 48 hours, a surge in global copper prices has reignited interest in copper scrap recycling—especially among DIYers and small-scale recyclers. With copper rod price and copper strip price hitting multi-month highs, knowing how to efficiently recover clean copper from insulated wire can significantly boost your returns. Whether you’re salvaging old electronics, HVAC systems, or construction leftovers, stripping copper wire properly is essential.
Stripping copper wire isn’t just about removing insulation—it’s about maximizing value while staying safe and legal. Burning copper wire for scrap, for instance, is illegal in many areas due to toxic fumes. This guide shows you the best way to strip copper wire without damaging the metal or risking fines.
2. Why Strip Copper Wire?
Unstripped copper wire fetches far less at scrap yards than bare bright copper. Clean, stripped copper can sell for 2–3 times more per pound. Plus, many recyclers won’t accept insulated wire at all. By stripping it yourself, you control quality and profit.
Common sources include:
- Old appliance cords
- HVAC wiring (often linked to aircon copper pipe systems)
- Demolition site leftovers
- Industrial motor windings
3. Tools You’ll Need
The right tool depends on wire thickness and volume:
- Manual wire strippers (for thin, household wires)
- Automatic wire stripping machines (for bulk jobs)
- Utility knife (use with extreme caution)
- Heat gun (only for specific insulation types—never open flame!)
Avoid burning copper wire for scrap—it releases dioxins and ruins copper purity, lowering resale value.
4. Step-by-Step: Best Way to Strip Copper Wire
4.1. Sort Your Wire
Separate copper wire by type: THHN, Romex, coaxial, etc. Only strip pure copper—not aluminum or copper-clad steel. Confusing copper bonded steel or copper clad ground rod material with solid copper will cost you at the yard.
4.2. Choose Your Method
For small batches: Use manual strippers. Cut a small slit in the insulation, then peel it back gently to avoid nicking the copper.
For long runs: Feed wire into an automatic stripper. These handle everything from thin strands to thick 6-gauge cables used in grounding systems like copper earth rod installations.
4.3. Clean and Bundle
Wipe stripped copper with a dry cloth. Coil it neatly—scrap yards prefer bundled bare bright copper. Never mix with copper strip, copper tubing, or copper rod unless specified.
5. Common Mistakes to Avoid
Don’t assume all red or shiny wire is pure copper. Some ‘copper’ cables are actually copper clad steel earth rod rejects or aluminum with copper coating.
Avoid using pliers or teeth—this damages the copper and reduces value.
Never burn insulation off. Not only is it hazardous, but it oxidizes the surface, turning high-grade copper into low-grade ‘tinned’ scrap.
6. What About Other Copper Products?
While this guide focuses on wire, you might also encounter related items:
- Copper strip: Often used in earthing (e.g., copper strip for earthing, 25x3mm). Thin copper strips or nickel plated copper strip should be kept separate.
- Copper rod: Includes copper round bar, copper brazing rod, or copper welding rod. These are typically sold by weight—check copper rod price before scrapping.
- Copper tubing: From AC units (aircon copper tube) or plumbing (15mm copper pipe). Clean and straighten before selling.
Note: Items like copper bonded earthing rod or copper clad steel ground rod contain steel cores—scrap value is much lower than solid copper.
7. Maximizing Profit: Know the Market
Check local rates for:
- Bare bright copper wire
- Copper strip price (especially 1mm copper strip or beryllium copper strip)
- Copper rod price vs. copper ingot price
Search ‘copper strip near me’ or ‘copper bars for sale’ to compare buy-back rates. Some yards pay premium for flexible copper bus bar or copper flat bar in good condition.
Also, keep an eye on ac copper pipe price—if you’re dismantling old HVAC systems, those copper lines add up fast.
8. Safety First
Always wear gloves and eye protection. Work in a well-ventilated area. If using power tools, unplug when adjusting blades. And never strip live wires—ensure circuits are de-energized.
9. Conclusion
Stripping copper wire for scrap is a smart, eco-friendly way to earn extra cash—especially when copper prices are high. By using the right tools, avoiding burning, and sorting materials correctly (including distinguishing solid copper from copper bonded or copper clad variants), you’ll get top dollar. Whether you’re handling copper strip wire, copper rod for welding, or leftover air conditioner copper pipe, clean, organized scrap always wins.
