Scrap metal prices in El Cajon change by the week, sometimes by the day, and if you don’t know why, you can end up leaving real money on the table. C4S Recycling buys ferrous and non-ferrous metal from homeowners, contractors, and property managers across East County, and one question comes up at the scale more than any other: why did today’s price differ from last month’s? Here’s the honest answer, plus what you can control to get paid more for the load you’re already hauling in.
How Scrap Metal Prices Are Actually Set
Scrap prices aren’t pulled out of the air. Non-ferrous metals like copper and aluminum trade on global commodity markets, and the London Metal Exchange is where the world’s benchmark reference prices for those metals get discovered every trading day. When copper futures move on the exchange, buyers up and down the supply chain — including local yards like ours — adjust what they can pay, usually within a day or two.
Ferrous scrap (steel and iron) works on a similar principle but trades through a different set of regional and export benchmarks tied to steel mill demand. That’s part of why a mixed load of copper wire and steel pipe gets two very different per-pound numbers at the same scale — they’re not riding the same market at all.
Ferrous vs. Non-Ferrous: Why the Same Truckload Pays Differently
If you’ve ever wondered why a load that’s “half copper, half steel” doesn’t pay like it’s all one material, the split is the reason. Ferrous metals contain iron and are magnetic; non-ferrous metals — copper, aluminum, brass, stainless — don’t respond to a magnet and generally carry a much higher price per pound. We cover the difference in depth, including a quick magnet test you can do yourself before you ever load the truck, in our ferrous vs. non-ferrous metal guide.
What Actually Changes Your Payout at the Scale
Two loads of the exact same metal can pay differently depending on condition. Clean, sorted, bare copper wire pays more per pound than the same wire still jacketed in insulation. Aluminum free of steel brackets, screws, or attached plastic weighs in cleaner and prices higher than mixed scrap. Rust, dirt, and contamination don’t just look bad — they get weighed into your total and priced down accordingly.
Sorting by material before you arrive is the single biggest lever a walk-in seller has. Separate copper from aluminum, pull steel fasteners off aluminum window frames, and keep wire dry. It takes ten extra minutes at home and it shows up directly in what we can pay you at the scale.
Copper, Aluminum, Brass, and Steel: Which Pays Best Right Now
Copper consistently sits at the top of the per-pound scale among common household and job-site scrap, with brass close behind. Aluminum pays less per pound than copper but adds up fast in volume — old AC housings, window frames, and gutters are common sources. Steel and iron pay the least per pound of the group but are usually the highest-volume material on a demolition or cleanout job. Because pricing shifts with the broader metals market, we quote current rates by phone or in person rather than posting a number that’s stale by the following week — call ahead and we’ll give you today’s actual rate before you make the drive.
How to Get the Best Price for Your Load
- Sort by material — copper, aluminum, brass, and steel separately, not mixed in one pile.
- Strip insulation off wire where it’s practical; bare copper pays more than insulated wire.
- Remove non-metal attachments — plastic housings, rubber, wood — before weigh-in.
- Keep metal dry; wet scrap can weigh in artificially heavy and slow down the sort.
- Call ahead for today’s rate on your specific materials before loading the truck.

Contractors and Job Sites: Pricing for Bulk and Recurring Scrap
Walk-in pricing is only half the picture. HVAC, mechanical, and demolition contractors generating recurring scrap — AC units, chillers, copper wire, ductwork — deal with volume, not a single truck bed, and that changes the conversation. We set up commercial accounts with scheduled pickup, roll-off containers, and net-terms billing so a job site’s scrap becomes a line item instead of a hauling problem. If your crew is already pulling AC units or chillers off a job, our guide to recycling an old AC unit or chiller covers the EPA refrigerant-recovery step that has to happen before that unit can be scrapped at all.
We serve contractors and walk-in sellers across El Cajon, Santee, La Mesa, Lakeside, Spring Valley, Rancho San Diego, and Alpine — see our full service area coverage for the East County cities we run regular pickups in. C4S Recycling is the newer storefront for the scrap side of C4S Demolition, our sister company’s 20-plus years running demolition, hauling, and HVAC recycling jobs in East County — read more on our About Us page. The pricing discipline is the same crew, just under its own name now.
Frequently Asked Questions
Why do scrap metal prices change so often?
Non-ferrous metals like copper and aluminum trade on global commodity markets, so the benchmark price moves daily. Ferrous scrap follows regional steel-mill demand. Local buyers adjust what they pay as those markets move, which is why a price from three weeks ago may not hold today.
What’s the best day to sell scrap metal in El Cajon?
There isn’t a fixed “best day” — prices track the metals market rather than the calendar. The safest move is to call ahead the same day you plan to bring in a load and confirm the current rate for your specific materials.
Do you pay more for sorted scrap?
Yes. Clean, sorted-by-material loads free of contamination and non-metal attachments weigh in more accurately and price higher than mixed, dirty loads of the same metal.
How do I get started with a commercial scrap account?
Call 760-521-9066 to set up scheduled pickup, a roll-off container, or net-terms billing for your job site or property. More common questions on materials, hours, and pricing are covered on our FAQ page.
