Key Takeaway

Copper grades directly affect your payout. Learn the difference between bare bright, No.1, No.2, and insulated wire.

Copper is priced by grade, and the difference between grades can be substantial. Here's how to understand what you have.

Bare Bright Copper

The top grade. Clean, uncoated, unalloyed copper wire at least 1.5mm in diameter. No insulation, no tinning, no solder. Freshly stripped electrical wire from large-gauge installations qualifies. This grade commands the highest price.

No.1 Copper

Clean, uncoated copper pipe and wire that may have slight oxidation but no paint, heavy coatings, or solder. Plumbing pipe in good condition is typically No.1. Copper sheet and bus bar also often grades as No.1.

No.2 Copper

Copper with solder, paint, light alloy, or oxidation. Plumbing pipe with soldered joints, painted copper, old radiator fins. Most mixed copper items fall here. Still valuable — just not as valuable as No.1.

Insulated Copper Wire

Wire still inside plastic or rubber insulation. Price depends on the copper recovery percentage. House wiring (Romex) is typically 60-70% copper by weight. Thin telephone or data cable may only be 20-30% copper, so it pays much less.

Copper Tanks and Cylinders

Old hot water cylinders and tanks are usually unalloyed copper and grade at No.1 or No.2 depending on condition.
