Why Strip Copper Wire?

Stripping copper wire is essential for:

• Scrap metal recycling – Bare copper fetches a higher price than insulated

• Electrical installations – Clean, undamaged wire ensures solid connections

• Craft and DIY projects – Exposed copper is easier to shape and solder

Best Methods to Strip Copper Wire

1. Manual Wire Strippers (Best for Small Jobs)

A handheld wire stripper is ideal for electricians and DIYers handling short lengths.

• How it works: Choose the right gauge hole, clamp, and pull off insulation

• Pros: Precise, safe, cheap (under $20)

• Cons: Slow for large volumes

✅ Best for: Household repairs, short wires (under 10 feet)

2. Utility Knife or Razor Blade (Caution: Sharp!)

• How it works: Score along the insulation and peel it off

• Pros: Simple, no extra tools

• Cons: Risk of injury and damaging the copper

⚠️ Best for: Experienced users with steady hands

3. Wire Stripping Machine (Best for High Volumes)

Automatic or manual crank wire stripping machines are perfect for scrap yards or serious recyclers.

• How it works: Feed wire through the machine; blades slit the insulation

• Pros: Fast, efficient, clean copper recovery

• Cons: Expensive upfront (manual: ~$100+, electric: $300+)

🔧 Best for: Large-scale scrap wire stripping operations

4. Heat Gun or Open Flame (Not Recommended for Indoors)

Some people burn off insulation, especially with heavy industrial cable.

• How it works: Heat melts insulation, which is then peeled or burned off

• Pros: Quick for thick wires

• Cons: Releases toxic fumes, illegal in many places, damages copper

❌ Best for: Last resort in outdoor, well-ventilated areas only

Safety Tips When Stripping Copper Wire

• Always wear gloves and safety glasses

• Disconnect all power before working on any electrical wiring

• Work on a stable, clean surface

• Avoid inhaling smoke or fumes—never burn plastic coatings indoors

• Keep blades sharp but handle with care

Choosing the Right Method Based on Wire Type

Tips to Maximize Copper Recovery Value

• Keep it clean: Strip all insulation for the best price per pound

• Separate by grade: Bright bare copper > #1 copper > #2 copper

• Avoid nicking the wire: Damaged copper fetches a lower price

• Store properly: Keep bare copper dry to prevent oxidation
