Direct answer
Start by separating bare copper, insulated wire, tubing, brass-colored alloys, and mixed assemblies. Use appearance, magnetism, weight, and visible construction as screening clues, then let the recycling yard make the final grade determination.
Begin with broad, observable groups
Copper scrap is easier to evaluate when the load is divided before any price calculation. Keep clean bare wire separate from insulated wire, plumbing tube, motors, radiators, brass fittings, and items that still contain steel, plastic, solder, or other attachments.
Color alone is not a reliable grade test. Fresh copper is reddish-orange, but oxidation, coatings, plating, lighting, and contamination can change its appearance. A magnet can help identify ferrous attachments, but a nonmagnetic result does not prove an item is copper.
- Keep material dry and remove only attachments you can handle safely.
- Photograph unusual items and record their weights before visiting a yard.
- Do not burn insulation or use unsafe chemical stripping methods.
Separate copper from copper alloys
Brass is a copper alloy and often looks yellow or gold rather than reddish. Bronze and specialty alloys can overlap visually. Separate obvious fittings, valves, and fixtures from wire and tubing instead of combining everything as one copper grade.
Recycling specifications exist to create consistent commercial descriptions, but individual yards may use different receiving categories. Ask the yard what its grade names mean and whether solder, paint, insulation, connectors, or corrosion affect the offered price.
Estimate only after sorting
Multiply the accepted weight for each grade by the yard's quoted price for that grade, then add the subtotals. An estimate is a planning tool, not a guaranteed payout: scale readings, moisture, contamination, local demand, and the yard's inspection can change the final result.
ScrapValue can help organize weights, grades, saved loads, and user-entered yard quotes. It does not identify material or set a recycling yard's official grade.
Common questions
Can a magnet confirm that an item is copper?
No. Copper is not magnetic, but many other metals are also nonmagnetic. Use the magnet only to find ferrous parts, then confirm the material through construction, markings, and the receiving yard.
Should insulated copper wire be mixed with bare copper?
Usually no. Insulation changes the recoverable copper content, so keeping insulated and bare wire separate makes the load easier for a yard to inspect and quote.
Does ScrapValue guarantee a payout?
No. It produces estimates from weights and prices entered by the user. The recycling yard determines the accepted grade, weight, and final payout.
