Why can two bundles of copper cable with the same weight have different scrap values? It comes down to the grade.
When selling copper cable scrap in Perth, scrap buyers grade it based on the amount of recoverable copper, insulation, cleanliness and contamination. Clean, bare copper generally receives a higher grade, while insulated cable or cable mixed with other materials may be graded lower.
Understanding these differences helps you separate your copper cable correctly and know what buyers are looking for before you take your scrap to the yard.
Why Copper Cable Is Graded
Copper cable comes in many forms — bare wire, insulated cable, tinned wire, and mixed cable with other metals attached. Each type has a different purity level once processed, and purity is what buyers and smelters pay for. Insulation, coatings, corrosion, and mixed metals all lower the recoverable copper content, so grading exists to price each load accurately rather than paying a flat rate for all wire.
The Main Copper Cable Grades in Perth
1. Bare Bright Copper Wire – Highest Grade
Bare bright copper is clean, stripped copper wire with no insulation or coating. It should be bright in appearance and free from paint, solder, fittings and significant oxidation.
What makes it different: Almost all of the weight is copper, with very little material that needs to be removed during recycling.
Typical examples: Clean electrical copper wire that has been stripped of its insulation.
2. #1 Copper
Clean, unalloyed copper without insulation, but may show light surface oxidation or tarnish. It pays slightly less than Bare Bright due to minor surface impurities.
What makes it different: No insulation, light tarnish only, still high purity.
Typical examples: Copper pipes, bus bars, clean wire with minor discolouration.
3. #2 Copper
Copper with more visible oxidation, minor coatings, or slight impurities. Recovery rate is lower than #1, so pricing drops accordingly.
What makes it different: Noticeable oxidation or coatings that reduce purity.
Typical examples: Copper with solder joints, paint marks, tarnished tubing.
4. Insulated Copper Wire (ICW)
Wire still covered in plastic or rubber insulation. Because the insulation has to be stripped or burned off before the copper can be sold, buyers price ICW lower — usually based on estimated copper content per kilo.
What makes it different: Insulation intact, yield varies 20–80% depending on wire thickness and insulation ratio.
Typical examples: Household wiring, extension cords, unstripped electrical cable.
5. Christmas Light Wire / Low-Grade Cable
Thin-gauge wire with a high proportion of insulation and very low copper yield. This is the lowest-paying copper cable category.
What makes it different: Very thin gauge, high insulation-to-copper ratio, under 30% yield.
Typical examples: String lights, thin appliance cords, low-gauge wiring.
The Main Copper Cable Grades in Perth
| Grade | Description | Copper Yield | Payout Level |
|---|---|---|---|
| Bare Bright | Clean, uncoated wire, no insulation or oxidation | ~99% | Highest |
| #1 Copper | Clean, unalloyed, light tarnish allowed | ~94–96% | High |
| #2 Copper | Visible oxidation, solder, minor coatings | ~88–92% | Medium-High |
| Tinned Copper | Bare copper with thin tin coating | ~90–95% | Medium-High |
| Insulated Wire (ICW) | Plastic/rubber insulation intact | 20–80% | Medium-Low |
| Christmas Light Wire | Thin-gauge, high insulation ratio | Under 30% | Lowest |
How It’s Graded On-Site
Your load is weighed on arrival, then visually inspected for insulation, oxidation, coatings, and attachments. A section may be test-stripped to confirm purity before a grade is assigned and priced at the current market rate. Mixed loads with different grades tangled together are usually priced at the lowest grade present, unless sorted beforehand.

FAQs
1. What is the highest grade of copper wire scrap?
Clean, bare bright copper wire is usually the highest-value grade because it has no insulation and gives the highest amount of recoverable copper.
2. How do scrap yards grade insulated copper cable?
Insulated copper cable is graded based on things like recoverable copper content, cable type, insulation, and contamination. Cable with more copper generally gets a better grade than heavily insulated cable with very little copper inside.
3. Do I need to strip copper cable before selling it?
No. You can sell insulated copper cable without stripping it. Stripped copper often gets a higher price per kilogram, but whether it’s worth stripping depends on the type of cable and how much copper it contains.
4. Is insulated copper wire worth money in Perth?
Yes. Insulated copper cable still contains recoverable copper and is regularly bought by scrap metal recyclers. Its value depends on the cable grade, copper recovery, condition, weight, and current scrap market rates.
5. Where can I sell copper cable scrap in Perth?
