1. Introduction
In the past 48 hours, scrap metal recyclers across the U.S. and Europe have reported a surge in demand for clean, bare bright copper—driven by rising copper prices and supply chain shifts in renewable energy infrastructure. With copper rod price and copper strip price both trending upward, knowing how to properly strip copper wire can significantly boost your returns.
Stripping copper wire isn’t just about removing insulation—it’s about preserving the metal’s purity and maximizing resale value. Whether you’re salvaging from old appliances, construction sites, or HVAC systems (like aircon copper pipe), this guide shows you the best way to strip copper wire safely and profitably.
2. Why Stripping Copper Wire Matters
Recyclers pay far more for bare copper than insulated wire. For example, stripped ‘bare bright’ copper can fetch 2–3 times the price of insulated cable. Burning copper wire for scrap is not only illegal in many areas due to toxic fumes—it also damages the copper, lowering its grade and value.
Additionally, understanding related copper products—like copper rod for welding, copper bonded earthing rod, or flat copper strip—helps you identify high-value materials during salvage operations.
3. Tools You’ll Need
- Manual wire stripper (for small jobs)
- Automatic wire stripper or cable ripper (for medium volumes)
- Rotary wire stripper or bench-mounted machine (for large-scale operations)
- Utility knife (use with caution)
- Safety gloves and eye protection
Avoid using heat guns or open flames—burning copper wire for scrap releases hazardous dioxins and ruins the metal’s surface.
4. Step-by-Step: Best Way to Strip Copper Wire
4.1. Sort Your Wire First
Separate copper wire by type: THHN, Romex, coaxial, or motor windings. Look for markings like ‘CU’ or ‘Copper.’ Avoid aluminum or copper-clad steel—these have lower value. Copper clad steel ground rod and copper bonded steel may look like pure copper but contain steel cores.
4.2. Choose the Right Tool
For thin household wiring (14–10 AWG), a manual stripper works fine. For thick industrial cables or stripping wire for scrap in bulk, invest in an automatic stripper. These can process hundreds of feet per hour and cleanly separate insulation from copper strip wire or solid copper rod.
4.3. Strip Without Damaging the Copper
Make a shallow longitudinal cut along the insulation—don’t nick the copper inside. Peel back the sheath and pull it off. For multi-strand wire, twist strands gently before stripping to prevent fraying.
If you’re stripping copper wire for recycling from HVAC units, you’ll often encounter aircon copper tube or 15mm copper pipe—these aren’t wire but solid copper tubing and should be cut and sold separately.
4.4. Clean and Bundle
Wipe stripped copper with a dry cloth to remove residue. Bundle bare bright copper separately from #1 or #2 copper. Never mix with brass, steel, or painted copper.
5. Common Mistakes to Avoid
5.1. Burning Insulation Off
Despite old myths, burning copper wire for scrap is dangerous and counterproductive. It oxidizes the surface, turning valuable bare bright into low-grade ‘tinned’ copper.
5.2. Confusing Copper Alloys
Not all shiny metal is pure copper. Beryllium copper strip, nickel plated copper strip, or copper alloy strip have different values. Similarly, copper clad earth rod and copper bonded ground rod contain steel and shouldn’t be mixed with pure copper scrap.
5.3. Ignoring Copper Byproducts
While stripping, you might find copper strip near me—like copper edging strip, copper roof strip, or even copper tape for snails (used in gardening). These thin copper strips can be collected and sold as ‘copper metal strips’ if clean.
6. Bonus: Identifying High-Value Copper Items
Beyond wire, keep an eye out for:
- Copper round bar or round bar copper (often used in machining)
- Copper bus bar or flexible copper bus bar (from electrical panels)
- Copper earth strip 25x3mm (used in grounding systems)
- Copper rod welding leftovers or copper to copper brazing rods
Even small items like 1mm copper strip or roll of copper strip add up in bulk. Check copper strip price trends—thin copper strips from transformers or motors are especially valuable.
7. Conclusion
Stripping copper wire properly is a simple skill that pays off—literally. By using the right tools, avoiding burning, and sorting carefully, you ensure top scrap value. With copper rod price and copper strip price on the rise, now’s the perfect time to refine your technique. Whether you’re salvaging from old pipework, earthing rods, or AC copper lines, clean, bare copper always wins.
