Most scrap yards pay you based on what metal you bring in — but if you don't know what you're holding, you're leaving money on the table. Whether you've got a pile of old wire, some automotive parts, or a bin of mixed material sitting in a garage in Oshawa, knowing how to identify your metals before you sell is one of the most practical things you can do. It affects your payout. It affects how buyers bid. And right now, with scrap metal prices today shifting week to week, getting your sorting right matters more than ever.
This guide breaks it down simply. You don't need a lab. You need a magnet, your eyes, and a few minutes. Let's walk through it.
Why Metal Identification Matters for Scrap Metal Prices Today
Scrap metal isn't priced as one category. Copper, aluminum, steel, cast iron, stainless — they all trade at different rates, and the spread between the highest and lowest can be dramatic. Copper wire regularly fetches multiples of what steel earns per pound. If your load arrives at the yard as "mixed metal," you often get sorted at the buyer's discretion — and that means the buyer benefits, not you.
The better your documentation, the better your position. Sorted loads with clear identification give buyers more confidence. More confidence drives stronger bids. That's not theory — it's how competitive scrap auctions work. Platforms like smashrecycling.ca are built on exactly this principle: documented, well-described inventory gets more serious attention from vetted buyers.
The other reason identification matters: some metals — catalytic converters especially — have wildly different values depending on the exact grade. A standard catalytic converter off a commuter car is not the same as a diesel unit or a large-format cat off a truck. Knowing the difference is money.
The Magnet Test: Your First and Most Reliable Tool
Start here. A basic refrigerator magnet works. A rare earth magnet from a hardware store works better. The rule is straightforward:
- Magnet sticks strongly: You're looking at ferrous metal — steel or iron. Lower scrap value per pound, but high volume makes it worthwhile.
- Magnet sticks weakly or inconsistently: Could be certain grades of stainless steel. Some stainless is slightly magnetic depending on its composition. Don't assume it's regular steel.
- Magnet doesn't stick at all: Non-ferrous. This is where the money is. Copper, aluminum, brass, bronze, zinc, lead — none of these are magnetic.
Non-ferrous metals are why serious scrappers keep a magnet in their pocket on every job. A pile that looks like junk steel might hide copper fittings, aluminum brackets, or brass valves. Run the magnet before you toss anything into the wrong bin. In a yard environment in Ontario, this one habit can meaningfully change your payout at the end of the month.
One important note: the magnet test tells you ferrous vs. non-ferrous. It doesn't tell you which non-ferrous metal you have. For that, you need your eyes — and a few more tests.
Visual Identification Guide: Copper, Aluminum, Brass, and Steel
Once the magnet tells you something is non-ferrous, here's how to narrow it down visually:
Copper
Copper is one of the most visually distinct metals in scrap. Fresh copper is a reddish-orange, almost salmon color. Aged or oxidized copper turns green (the patina you see on old roofing and plumbing). It's heavy for its size, malleable, and bends without snapping. Electrical wire with copper core is one of the most common finds. Strip the insulation and check the core — bright orange-red means copper.
Copper is consistently one of the highest-value metals in the non-ferrous category. Bare bright copper wire, #1 copper tubing, and copper bus bars all trade at premium rates. If you're selling scrap metal in Canada on GetMyScrap, knowing your copper grades (bare bright, #1, #2, insulated) before you go in is worth the extra few minutes of prep.
Aluminum
Aluminum is light — noticeably lighter than steel or copper of the same size. It's silver-grey in color, sometimes with a dull matte finish. It won't rust (it oxidizes, forming a thin white-grey layer, but won't turn brown). Aluminum is everywhere in scrap: window frames, automotive wheels, engine blocks, siding, food-grade cans, and electrical cable. It bends but can snap if it's cast aluminum versus extruded or sheet.
Cast aluminum (engine blocks, transmission housings) trades differently than clean sheet or extrusions. Dirty or painted aluminum is discounted. When possible, strip attached steel bolts, rubber gaskets, and insulation before weighing. Clean aluminum gets better offers.
Brass and Bronze
Brass is a yellow-gold color — warmer than aluminum, darker than gold. It's heavier than aluminum and non-magnetic. You'll find it in plumbing valves, fittings, musical instruments, door hardware, and some electrical components. Bronze is similar but with a darker, more reddish-brown tone and often found in marine applications, bushings, and bearings.
Both are valuable. Brass is one of the more commonly misidentified metals — people sometimes confuse it with steel that's been painted or with zinc. The weight and color combination usually gives it away. If it's yellow and heavy and the magnet ignores it, you've got brass.
Steel and Iron
Steel and iron are the workhorses of scrap. Heavy, magnetic, and found everywhere — structural beams, car bodies, appliances, pipe, and hardware. Steel is lower in value per pound than non-ferrous metals, but it moves in high volumes. Cast iron (old stoves, engine blocks, manhole covers) is heavier and more brittle than steel and trades at its own rate.
Stainless steel is worth separating. It's non-magnetic or weakly magnetic, has a bright finish, and resists rust. Stainless pulls stronger prices than regular steel. Check kitchen equipment, food processing gear, and medical instruments — these are common stainless sources.
Identifying Catalytic Converters Before You Sell
Catalytic converters are their own category and deserve special attention. They contain platinum group metals (PGMs) — platinum, palladium, and rhodium — and their value varies enormously based on the type, vehicle make, and condition. A catalytic converter auction is not like selling steel by the pound. Buyers are bidding on the internal substrate and what it yields when processed.
Visually, catalytic converters look like a section of exhaust pipe with a larger canister in the middle. The substrate inside is either ceramic (honeycomb pattern) or metallic foil. Both contain PGMs, but in different concentrations. Diesel particulate filters (DPFs) look similar but trade at different rates than gasoline cats.
For Oshawa sellers and yards dealing in automotive scrap, sorting cats by type before listing them is important. Serial numbers on the converter housing can help identify the vehicle origin and expected yield. Platforms that support serial tracking and photo documentation — like SMASH — make this process transparent for both sellers and buyers. A well-documented catalytic converter listing gets taken more seriously than a vague description.
If you're not sure what you have, photograph both ends of the converter, capture any visible serial numbers, and note the vehicle it came from if you know it. That information has real value in a competitive bid environment.
Sorting Your Scrap in Oshawa: Practical Tips Before You Sell
Oshawa has a strong industrial and automotive history, which means local scrappers often deal with a mix of ferrous, non-ferrous, and specialty metals. Before you bring anything in or request a pickup, a bit of prep makes a real difference.
- Run the magnet first. Sort ferrous and non-ferrous into separate piles before anything else.
- Separate your copper grades. Bare wire, insulated wire, tubing, and dirty copper all price differently. Don't mix them.
- Pull out your stainless. It looks like steel but pays better. Keep it separate.
- Document your catalytic converters. Photos and serial numbers matter. Don't throw cats in a bulk pile.
- Clean up where you can. Remove rubber, plastic, and attached hardware from non-ferrous metals. Contamination reduces your payout.
- Weigh what you can at home. Knowing your approximate weights before you go in helps you verify the ticket at the yard.
For scrap metal recycling in Ontario, taking these steps means you arrive informed. You're not guessing. And when you're working with a platform that puts your load in front of multiple vetted buyers, your preparation directly affects the bids you receive. You can explore Canadian scrap metal guides for more detailed breakdowns on specific metals and grades.
How SMASH Connects Sorted Loads to Competitive Buyers
Here's where sorting pays off in a measurable way. When you bring a well-identified, well-documented load to the market — whether it's non-ferrous metals, cores, or catalytic converters — you're not at the mercy of one buyer's offer. SMASH puts your inventory in front of multiple vetted buyers who are actively competing.
Competition can help reveal the market. A single phone call to one yard gives you one data point. A competitive auction gives you a clearer picture of what your material is actually worth right now. With scrap metal prices today varying by region, grade, and buyer demand, that difference matters.
SMASH supports photo documentation, serial tracking for cats, and auto-invoicing — features that make the process less paperwork-heavy for both sides. No subscription fees. The platform only works when the seller does. If you're dealing in volume — loads of copper, pallets of aluminum, or regular automotive scrap out of Oshawa — that model is worth understanding.
Whether you're a first-time seller cleaning out a property or a yard operator moving regular loads, the process starts with knowing what you have. Get a fair price for your scrap today by arriving prepared, sorted, and informed.
For Oshawa scrap metal services, GetMyScrap makes it straightforward to connect with the right buyers — no guessing, no cold calls, no leaving money behind because your load was labeled "mixed."

Frequently Asked Questions
Q: How do I check scrap metal prices today in Oshawa, Ontario?
Scrap metal prices today change frequently based on global commodity markets, local demand, and metal grade. Your best move is to contact a local buyer or use a platform like GetMyScrap or SMASH where you can get competitive offers on your specific material. Prices can vary significantly between buyers, so getting multiple quotes is always worth it.
Q: What's the easiest way to tell if metal is copper or brass?
Both are non-magnetic and valuable, but copper is a distinctive reddish-orange color while brass is yellow-gold. Brass is also an alloy (copper and zinc), so it tends to be slightly harder and less flexible than pure copper. Weight and color together are usually enough to distinguish them visually.
Q: Does sorting my scrap actually get me a better price?
Yes — consistently. Mixed loads are typically priced conservatively because the buyer is taking on the sorting labor and uncertainty. Clean, sorted, identified loads give buyers more confidence, which tends to produce stronger offers. This is especially true in auction environments where multiple buyers are competing on the same material.
Q: How do catalytic converter auctions work, and why should I care about the serial number?
Catalytic converter auctions work by listing your cats with as much identifying information as possible — photos, serial numbers, vehicle source — and letting multiple buyers bid based on expected PGM yield. Serial numbers help buyers look up historical assay data for that converter type, which increases their confidence and typically their bid. Without that information, buyers discount for uncertainty.
Q: Where can I sell scrap metal near me in Oshawa?
GetMyScrap connects sellers in Oshawa and across Ontario with scrap metal buyers, including pickup options for larger loads. SMASH offers a competitive auction format for yards and higher-volume sellers. Starting at getmyscrap.ca is the simplest way to find out what your material is worth without calling around to individual yards.
