Ferrous vs. Non-Ferrous Scrap Metal: What Every Canadian Recycler Needs to Know
Most people selling scrap metal for the first time make the same mistake — they treat all metal the same. They haul everything to the yard and take whatever price they're offered. If you're doing that, you're leaving money on the table. Understanding the difference between ferrous and non-ferrous scrap metals is the single most useful thing you can do before your next trip to the yard, especially if you're recycling in Saint John or anywhere else in New Brunswick.
This isn't complicated science. It's practical knowledge that changes what you sort, what you carry, and what you get paid. Let's break it down.
What Makes a Metal Ferrous — and Why It Matters for Scrap Metal Recycling
The word "ferrous" comes from the Latin ferrum, meaning iron. Any metal that contains iron is ferrous. That covers a massive range of everyday materials — structural steel, cast iron engine blocks, steel beams, rebar, car frames, old appliances, and most of what you'd pull out of a demolition or auto salvage job.
Ferrous metals are magnetic. That's your fastest field test. Hold a magnet to the piece. If it sticks, it's ferrous. Scrap yards across New Brunswick use this same basic rule when they're sorting incoming loads. It sounds simple, but knowing it upfront saves you from mixing high-value non-ferrous material into a low-value steel pile.
Price-wise, ferrous metals typically sell at a much lower rate per pound than non-ferrous. Steel and iron prices shift with construction demand, manufacturing cycles, and global trade conditions. In 2026, global steel markets remain volatile — infrastructure spending in some regions is up, but overcapacity issues in certain export markets continue to apply downward pressure.

Non-Ferrous Scrap: Copper, Aluminum, and the Metals That Pay More
Non-ferrous metals contain little to no iron. They don't rust the same way, they're generally lighter, and — critically — they command significantly higher prices per pound. This category includes copper, aluminum, brass, lead, zinc, nickel, and the platinum group metals found in catalytic converters.
Copper is the star of non-ferrous scrap. Bare bright copper wire, #1 copper pipe, and clean copper tubing all fetch premium prices. Copper scrap prices in Saint John fluctuate with London Metal Exchange (LME) rates and Canadian dollar movements, so what you got paid six months ago might not be what the yard offers today. Always check current rates before you commit to a sale — and never assume the first offer you hear is the market rate.
Aluminum is everywhere — window frames, car rims, drink cans, engine components. It's lighter than copper and pays less per pound, but it adds up fast if you're accumulating consistently. Brass, which is an alloy of copper and zinc, sits in its own pricing tier. Old plumbing fittings, valves, and hardware can surprise you on the scale.

Catalytic Converters: The Most Misunderstood Non-Ferrous Scrap
Catalytic converters sit in their own league. They're technically part of a ferrous steel shell, but what makes them valuable is the non-ferrous content inside — platinum, palladium, and rhodium. These platinum group metals (PGMs) are among the most valuable materials in the recycling stream.
A lot of sellers in New Brunswick don't realize they can sell catalytic converters online rather than just dropping them at a local yard for a flat rate. Online auction platforms create competition among buyers, which often reveals a stronger market price than a single buyer will offer face-to-face. That's exactly the model SMASH is built on — put your cats in front of vetted buyers, let the market compete, and find out what they're actually worth.
Pricing on cats is based on make, model, year, and the specific converter code. VIN lookup and serial tracking take the guesswork out of grading. Never strip a cat without documenting it — photo documentation and serial tracking protect you and give buyers the confidence to bid higher. SMASH includes these tools as part of the platform, not as an add-on.
One thing worth noting: regulations around catalytic converter sales have tightened in several provinces. Make sure you're working with a buyer who operates transparently and maintains proper documentation. If you're looking to find the best price for your scrap in Canada, the documentation trail matters as much as the price.
How to Sort Your Load Before You Sell — Best Scrap Metal Prices New Brunswick
Sorting isn't glamorous, but it's directly tied to what you get paid. Mixed loads get priced at the lowest common denominator. If you toss copper into a steel bin, you're selling copper at steel prices. That's an expensive mistake.
Here's a practical sorting approach before you take a load to a Saint John scrap yard or list it through an online platform:
- Magnetic test first. Separate ferrous from non-ferrous before anything else.
- Strip your copper. Insulated wire pays less than bare copper. Clean, stripped wire moves to a higher grade.
- Separate your aluminum grades. Cast aluminum (engine parts) grades differently than sheet or extrusion aluminum.
- Pull your cats. Don't let converters get lost in a general steel load. Track them separately with VINs or serial numbers if possible.
- Keep brass and bronze separate. Mixed yellow metals get priced lower than clean, sorted material.
- Document everything. Photos, weights, descriptions. Buyers pay more when the guesswork is removed.
For yard operators and individual sellers in Saint John, this sorting discipline becomes a habit that compounds over time. It takes extra effort upfront — but it shows up in your payout every single time.
How Competitive Pricing Actually Works for Scrap Metal Recycling in Saint John
Here's the problem with the old way of selling scrap: you call one buyer, they give you one number, and you have no idea if it's the market rate or a lowball. You take it because you don't have time to call ten more yards and compare.
That's a structural problem, not a personal failing. The information asymmetry between sellers and buyers has always favored buyers. Single-buyer transactions reward the buyer's knowledge, not the seller's material. This is why competitive auctions exist — not just for art and equipment, but for scrap metal.
Platforms like SMASH flip that dynamic. Instead of you chasing one buyer, vetted buyers compete for your load. More competition means better price discovery. It doesn't guarantee you'll hit a record price on every load — no platform can promise that — but it does mean the number you walk away with reflects what the market will actually bear, not just what one buyer felt like offering that morning.
For sellers in Saint John and across New Brunswick, this is especially relevant for higher-value non-ferrous loads — copper, cats, aluminum in volume. These are the materials where price swings matter most and where a few extra cents per pound compounds quickly across a full load.
You can access Saint John scrap metal services directly and get the process started without the runaround.
Ferrous vs. Non-Ferrous: Quick Reference for Canadian Scrap Sellers
Before you load the truck, run through this quick comparison. It applies whether you're a homeowner cleaning out a garage or a demolition crew working a commercial site.
- Ferrous metals: Steel, iron, cast iron, stainless steel (some grades). Magnetic. Lower price per pound. High volume is where ferrous value builds.
- Non-ferrous metals: Copper, aluminum, brass, lead, zinc, nickel, PGMs. Not magnetic. Higher price per pound. More sensitive to market swings.
- Catalytic converters: Hybrid — steel shell, PGM core. Sell separately. Pricing depends on make, model, and converter code. Document before selling.
- Alloys: Stainless steel, bronze, and other alloys may not be purely ferrous or non-ferrous — know your grade before you assume the price.
Prices fluctuate. Always check current rates before finalizing a sale. Spot prices for copper, aluminum, and PGMs move with global markets, and what a yard offers on any given day reflects those movements plus their own margin. Comparison sells — whether that's calling multiple yards or using an auction platform — put you in a stronger position.
If you're ready to stop guessing and start selling with real market visibility, get a fair price for your scrap today. Whether you're sorting a small residential load or managing a commercial recycling operation in New Brunswick, knowing your metals is the first step. The next step is putting them in front of buyers who compete for them.
Frequently Asked Questions
Q: How do I know if my scrap metal is ferrous or non-ferrous?
Use a magnet. Ferrous metals (steel, iron) will stick to a magnet. Non-ferrous metals like copper, aluminum, and brass won't. This is the same test scrap yards in Saint John use when sorting incoming loads. For alloys or metals you're not sure about, ask your yard — most are happy to identify material on the spot.
Q: What are copper scrap prices in Saint John right now?
Copper prices fluctuate daily based on London Metal Exchange (LME) rates and currency exchange. We don't publish live spot prices here — always check with your local yard or a real-time pricing platform before you sell. What you got quoted last month may be meaningfully different from today's rate. Platforms like SMASH help surface competitive market pricing rather than relying on a single quote.
Q: Can I sell catalytic converters online from New Brunswick?
Yes. Online platforms allow you to list catalytic converters for competitive bidding from vetted buyers across North America. This typically means better price discovery than a single local offer. You'll want to document serial numbers, photos, and vehicle information (VIN if available) before listing — this helps buyers price accurately and bid confidently.
Q: Is it worth sorting my scrap before taking it to a Saint John yard?
Absolutely. Mixed loads get priced at the lowest value metal in the pile. Sorting copper from steel, stripping insulated wire, and separating aluminum grades can meaningfully increase your payout. It takes time upfront, but the difference in price per pound between a mixed load and a clean, sorted load adds up — especially on larger volumes.
Q: What non-ferrous metals are most valuable to recycle in Canada?
Copper consistently leads on price per pound, followed by brass, then aluminum. Platinum group metals in catalytic converters are the highest value per unit but require proper grading and documentation to get market rate. Lead, zinc, and nickel also have active markets. Prices for all of these shift with global commodity markets — no static list of values stays accurate for long.
