Identifying Different Types of Copper Cable Scrap & Their True Yields

The Nightmare of the Mixed Cable Pile

If you are tearing down a commercial building or cleaning out an industrial warehouse, you are going to pull miles of wiring out of the walls. Eventually, you end up staring at a massive, tangled mountain of copper cable scrap. Some of it is thick black industrial cable. Some of it is white household wire. A lot of it is cheap blue internet cable.

Here is the brutal truth: if you scoop that entire pile into a truck and drive it to your local scrap yard, you are going to get robbed at the scale.

Brokers love seeing mixed loads of copper cable wire scrap because it gives them an excuse to pay you the absolute lowest rate. To protect your profits, you have to know exactly what you are holding. Let’s break down the different types of cable and how to identify your true metal yield.

High-Yield vs. Low-Yield: Knowing Your Copper Scrap Cable

When an industrial processor buys insulated wire, they don’t care about the plastic jacket. They only care about the “recovery rate”—which means the exact percentage of solid copper hiding inside. Here is how to sort your pile:

• High-Yield (60% to 80% Recovery): This is your THHN, Romex, and heavy industrial power cables. If you slice it open, you see thick, solid chunks of pure copper. Because the plastic skin is thin compared to the heavy metal core, this is the most valuable copper scrap cable you can sell.
• Medium-Yield (40% to 50% Recovery): Think of heavy extension cords, appliance wires, and standard stranded power cables. They still have a decent amount of copper, but the thick rubber jackets eat up a lot of the total weight on the scale.
• Low-Yield (Under 40% Recovery): This is Cat5/Cat6 data wire, telecom cables, and thin electronics cords. It looks bulky, but it’s mostly plastic \”fluff.\” The actual copper hairs inside weigh next to nothing.

How to Trade Bulk Cable Wire Scrap Like a Pro

A lot of guys ask if they should sit around and strip the plastic off their cables by hand to get the premium bare bright copper price. If you have a few feet of thick wire, go for it.

But if you are aggregating shipping containers full of wire, hand-stripping is physically impossible. You will drown in labor costs. True industrial players simply separate their wire by grade and ship the bales directly to global processors like BuySellScraps. We use massive mechanical granulators to chop and air-separate the plastic from the copper. Because we don’t have to guess your yield, we pay direct wholesale LME rates for your exact metal weight.
