It’s one of the most common points of confusion for anyone new to selling scrap copper: “bright” wire doesn’t mean shiny wire. Here’s what it actually means.
The real definition
Bright copper wire is copper that has been fully stripped of insulation, coating, or any other material, leaving clean, bare copper. It’s called “bright” because that’s the industry term for this grade — not a description of its appearance.
What it actually looks like
Freshly stripped copper is typically a dull, pinky-orange colour, not a polished shine. If your wire looks genuinely bright and shiny, it’s most likely been kept indoors, away from air and moisture, which slows the natural oxidation process. Wire that’s been stored outside or exposed to damp will tarnish faster and can be downgraded even if it’s still technically bright (fully stripped).
Why bright wire is worth the most
Because it requires no further processing before a buyer can melt and reuse it, bright wire consistently commands the highest price per kilo of any common copper grade — well above insulated cable, braziery, or lower grades like No.2 copper.
How to get the most value from bright wire
- Strip cable fully where you can, rather than selling it insulated
- Keep it dry and out of direct exposure to the elements before selling
- Keep it separate from other copper grades rather than mixing it into one load
The bottom line
If you’re stripping cable as part of your work, don’t undersell it by assuming “bright” is just a description of how it looks — it’s a specific, valuable grade, and it’s worth treating separately from the rest of your scrap.
