Bare bright vs #1 vs #2 copper: the grading guide that pays for itself

Copper is the metal that makes scrapping worthwhile. At more than thirty times the per-kilogram value of steel, it’s where the money in most loads is concentrated — and it’s also where the biggest difference between a good payout and a poor one lives. That difference comes down to one thing: grade. Two sellers can bring in the same weight of copper and walk away with payouts that differ by 30% or more, purely because of how their material was sorted and prepared. Here’s how the grading works and how to land on the right side of it.

Why grade matters so much

When a yard buys copper, it’s buying the cost of getting that copper back to a refinery-ready state. Clean, uncoated, uncontaminated copper needs almost nothing done to it — it can be melted and reused directly. Copper that’s coated in insulation, joined with solder, attached to brass fittings, or oxidised needs additional processing, and every step of that processing comes out of your payout. The grade is simply the yard’s shorthand for how much work your copper still needs.

The three grades you’ll hear most often at an Australian yard are bare bright, #1, and #2. Understanding the line between them is the single most useful thing you can learn as a copper seller.

Bare bright (the top rate)

Bare bright is the highest grade and commands the best price. To qualify, copper must be:

• Uncoated — no insulation, no tin or nickel plating, no paint
• Clean and bright — the characteristic shiny, salmon-pink colour of fresh copper, with no significant oxidation or tarnish
• A reasonable thickness — generally heavier than household wire; think the conductor inside thick cable once stripped

The classic source of bare bright is stripped electrical cable: the bright copper conductor that’s left after you remove the plastic insulation. It’s also the reason stripping is so often worth the effort. A spool of insulated cable might be graded as low-value insulated wire, but strip it and the same copper jumps to bare bright — frequently a 30–40% uplift on the same physical metal. For thick cable, that maths is overwhelmingly in your favour. For thin appliance cords, where you’d spend an hour stripping a few dollars’ worth, it usually isn’t.

#1 copper (clean, but not bright)

Number 1 copper is still clean and unalloyed, but it doesn’t meet the bright standard. It includes:

• Copper tube and pipe (clean, unsweated — no solder joints)
• Bus bar and heavy gauge wire that’s slightly tarnished or oxidised
• Clean copper that’s developed a patina from age but has no coatings or attachments

The defining features of #1 are that it’s solid copper with no solder, no fittings, no paint, and no excessive oxidation. Clean copper plumbing tube is the textbook example — provided you’ve removed any brass valves and there are no soldered joints dragging it down. Number 1 pays a little under bare bright, and the gap is usually not worth the effort of trying to brighten tarnished metal.

#2 copper (the dirty grade)

Number 2 is the catch-all for copper that’s clean enough to still be copper but carries problems:

• Soldered joints (common on plumbing offcuts)
• Paint or light coatings
• Some oxidation or corrosion
• Small amounts of attached non-copper material

A length of copper pipe with sweated solder joints, or painted copper, lands here. Number 2 still has real value — it’s copper — but it pays noticeably less than #1 because of the extra refining required to deal with the contaminants.

Insulated wire (a separate category)

Insulated copper wire is graded by how much actual copper it yields once the plastic is removed — the “recovery” percentage. Thick power cable with a high copper-to-insulation ratio pays well; thin, heavily-insulated data or appliance cable pays poorly. This is the category where the strip-or-don’t-strip decision lives, and the rule of thumb is thickness: the fatter the cable, the more worthwhile stripping becomes.

How to prepare copper for the best rate

A few minutes of sorting before you reach the yard protects your payout:

1. Separate by grade. Don’t let bare bright sit in the same bag as soldered offcuts — mixed loads get graded down to the lowest common denominator.
2. Remove brass and steel fittings. A brass valve on a copper pipe drags the whole piece to a lower grade. Cut it off and sell the brass separately.
3. Strip thick cable, leave thin cable. The thicker the conductor, the bigger the uplift from bare bright grading.
4. Don’t bother polishing. Trying to brighten oxidised copper isn’t worth your time; the grade difference rarely covers the effort.

You can check the current rate for each copper grade in your city on the copper price page, or run a specific quantity through the calculator to see the estimated payout range before you go. Walking into a yard knowing your bare bright from your #2 is how you make sure the grade on your receipt is the one your metal actually deserves.
