Most sellers leave money on the table before they even make a phone call. Why? They don't know what they're holding. Copper, aluminum, steel, zinc — they can look nearly identical to an untrained eye, but the price difference between them is massive. Knowing how to identify different metals before you find the best scrap metal prices today can be the difference between a decent haul and a great one.
This guide walks you through a practical, no-equipment-needed system for sorting your scrap. We'll cover visual cues, the magnet test, weight, and a few other field tricks that experienced yard operators use every day. Whether you're cleaning out a shop in Cincinnati or sorting a mixed load from a demolition job across Ohio, this is the foundation you need.
Why Metal Identification Matters for Scrap Metal Prices Today
Scrap yards price by material. A mixed load — copper wire tangled with aluminum conduit, or steel bolts in a bucket of brass fittings — gets downgraded. The yard has to account for the sorting labor, and they pass that cost onto you. Show up with sorted, identified material and you walk in with leverage.
Knowing your metals also protects you from undervaluation. If you hand a buyer a pile of "mixed metal," they'll price it at the lowest-value item in the pile. Copper scrap prices today can run several times higher than aluminum. Brass pays more than zinc. Every time you let a mixed load slide, you're subsidizing someone else's margin.
Platforms like SMASH Scrap — where verified buyers bid on your metal — reward well-documented, accurately identified loads. When buyers can see exactly what they're bidding on, competition increases. More competition means better price discovery. That's not theory — that's how auctions work.
The Magnet Test: Your First Tool for Sorting Scrap Metal
Grab a strong magnet. A rare earth (neodymium) magnet works best, but even a heavy fridge magnet gives you a starting point. The magnet test divides your scrap into two broad categories: ferrous and non-ferrous.
- Sticks to the magnet: Ferrous metal — iron, steel, most cast iron. These are lower-value materials sold by the ton.
- Doesn't stick: Non-ferrous — copper, aluminum, brass, bronze, stainless steel, lead, zinc, nickel. These are your higher-value materials, priced by the pound.
There's one important exception: stainless steel. Some grades of stainless are non-magnetic (304 series) while others will partially attract a magnet (430 series). If a silver-toned metal only weakly attracts the magnet and doesn't rust, it's likely stainless. Don't toss it in the steel bin — stainless commands a premium at most Ohio yards.
Once you've run the magnet test, set your ferrous pile aside. It's heavy, often bulky, and sold by weight in bulk. Your real sorting work starts with the non-ferrous pile.
Visual Identification: Reading Color, Texture, and Oxidation
After the magnet, your eyes are your best tool. Each metal has a distinct appearance — especially once you know what oxidation looks like on each one.
Copper
Fresh copper is a warm, reddish-orange. Oxidized copper turns dark brown, then eventually develops a green patina (verdigris). You'll find it in electrical wire, plumbing pipe, HVAC coils, and motors. Copper is dense and heavy for its size. If you're stripping wire, bare bright copper (clean, uncoated) is the top tier — #1 copper is clean pipe or wire, and #2 copper has solder, paint, or minor coating. Each grade prices differently, so read scrap metal pricing guides to understand the tiers before you sell.
Aluminum
Aluminum is silver-gray, lightweight, and doesn't rust — it oxidizes to a dull white powdery surface. It's one of the most common non-ferrous metals in a mixed load. Cans, window frames, car wheels, ladders, and electrical conduit are all common aluminum sources. The big pricing splits in aluminum are between cast (engine blocks, wheels) and sheet/extrusion (siding, frames). Cast aluminum is grittier and less uniform; extruded aluminum is smooth and consistent in cross-section.
Brass
Brass is yellow-gold in color — think faucets, valves, musical instruments, and shell casings. It's heavier than aluminum and noticeably denser. Oxidized brass turns dark brown or greenish. Don't confuse it with gold-painted steel — run the magnet. Brass won't attract.
Bronze
Bronze is similar to brass but redder and darker in tone. You'll find it in bearings, bushings, marine hardware, and some statuary. It's an alloy of copper and tin, and it prices close to brass — sometimes higher depending on grade and buyer.
Zinc
Zinc is a bluish-gray metal, often dull in appearance. Die-cast zinc (called "pot metal" in the trade) shows up in old carburetor housings, decorative hardware, and toys. It's heavier than aluminum but lighter than copper. Zinc prices significantly less than copper or brass, so it's worth separating cleanly.
Lead
Lead is extremely heavy for its size — the heaviest common scrap metal. It's a dull bluish-gray that scratches easily. You'll find it in old pipe (pre-1986 plumbing), wheel weights, and batteries. Handle lead with care — use gloves and wash hands thoroughly after contact.
Weight and Density: The Hand Test
Visual ID and the magnet get you most of the way there, but weight is your tiebreaker. Density differences between metals are dramatic enough to feel in your hand.
- Lead: Extremely heavy. A small piece feels shockingly dense.
- Copper: Heavy and dense. Noticeably heavier than aluminum of the same volume.
- Brass/Bronze: Heavy, similar feel to copper.
- Steel/Iron: Heavy, but not as dense as copper — and it rusts.
- Zinc: Medium weight. Heavier than aluminum, lighter than copper.
- Aluminum: Light. If it's silver-colored and shockingly light, it's almost certainly aluminum.
- Stainless steel: Heavy, silver, non-rusting, weakly magnetic or non-magnetic.
The hand test takes about two seconds. Pick it up. If a silver-colored piece feels as light as a plastic toy, it's aluminum. If it feels like it should be heavier than it looks — that's copper, brass, or lead. Practice this with known samples and your sorting speed will double within a week.
Identifying High-Value Specialty Items: Catalytic Converters and Motors
Beyond bulk scrap, some individual items carry serious value on their own. Catalytic converters are the most notable example. A single cat can be worth hundreds of dollars — sometimes more — because of the platinum group metals (PGMs) inside: platinum, palladium, and rhodium.
Cats don't look valuable from the outside. They're a dull gray canister on your exhaust system. But the serial number stamped on the shell tells the story. Different vehicle platforms have dramatically different PGM loadings, and that's why serial tracking and documentation matter so much. A catalytic converter auction — where verified buyers bid competitively based on documented serial numbers — is a fundamentally different outcome than selling to whoever answers the phone first. SMASH handles exactly this kind of load, with serial tracking built into the platform so buyers can price with confidence.
Electric motors are another item worth separating. The copper windings inside a motor make it worth more than plain steel. "Sealed units" (motors you haven't cut open) price differently than "copper breakage" (already-opened motors). Know what you have before you quote it. Sellers in Cincinnati and across Ohio who take the time to break out motors from mixed iron loads consistently see better returns.
If you want to check current scrap metal prices before you head to the yard, that's the move — know the market before you negotiate.
Putting It Together: A Simple Field Sorting System
You don't need a lab. You need a system. Here's a practical workflow for any mixed load:
- Magnet pass: Separate ferrous (sticks) from non-ferrous (doesn't stick). Set ferrous aside.
- Color sort: From your non-ferrous pile, pull anything red/orange (copper), yellow-gold (brass/bronze), and blue-gray (zinc or lead).
- Weight check: Any silver-colored metal — does it feel light (aluminum) or heavy (stainless, nickel)?
- Special items: Pull catalytic converters, electric motors, and sealed units for separate documentation and pricing.
- Wire grading: Separate bare bright copper, #1 insulated, #2 insulated, and communications wire into distinct piles.
- Document before you sell: Photos, weights, and serial numbers on cats. This is what platforms like SMASH are built around.
Cincinnati scrap sellers who bring sorted, documented loads to market aren't just being organized — they're negotiating from a stronger position. An Ohio yard receiving a clearly sorted load spends less time on intake, and some pass that efficiency back to sellers in better pricing.
The scrap metal market in 2026 rewards preparation. Commodity prices move fast — copper, aluminum, and steel prices all shift with global demand, energy costs, and trade flows. Knowing what you have, documenting it accurately, and selling into competitive markets is how you capture the best available price on any given day.

Frequently Asked Questions
Q: How do I quickly tell the difference between copper and brass at a scrap yard?
Color is your fastest tell. Copper is reddish-orange — almost salmon-toned when clean. Brass is distinctly yellow-gold, like a door hinge or faucet body. Both are non-magnetic and heavy, but the color difference is clear in good lighting. When in doubt, check the weight and density — copper is slightly denser than brass.
Q: What are scrap metal prices today in Cincinnati, Ohio?
Prices fluctuate daily based on commodity markets, regional demand, and yard-specific buying conditions. Cincinnati yards generally track national non-ferrous benchmarks, but local pricing varies. Always check current rates before you haul — use a resource like best-scrap-metal-prices.com for up-to-date pricing before you make the trip. Disclaimer: All metal prices fluctuate. Verify current rates before selling.
Q: Does aluminum stick to a magnet?
No. Aluminum is non-magnetic, which is why the magnet test is so useful — if your silver-colored metal doesn't attract the magnet and feels very light, it's almost certainly aluminum. The only common exception in scrap is certain grades of stainless steel, which may weakly attract a magnet but are still non-ferrous for pricing purposes.
Q: How do I sell a catalytic converter for the best price near me in Cincinnati?
Document the serial number stamped on the converter shell before you sell. That number determines the PGM value — buyers price off it. Selling into a competitive auction format, rather than calling one buyer, gives you price discovery. Platforms like SMASH are built specifically for this — vetted buyers bid on documented cats, which can reveal the real market value of what you're holding.
Q: Is it worth sorting my scrap before going to an Ohio yard?
Almost always, yes. Mixed loads get priced at the lowest-value material in the pile to account for sorting labor. Separating copper from aluminum, pulling motors and cats, and grading your wire takes time — but that time directly translates to better pricing per pound on your higher-value materials. For larger loads, the difference is significant.
