Why Knowing Your Metal Before You Sell Changes Everything
Most sellers leave money on the table before they ever pull into a yard. They show up with a mixed load, hand it over, and accept whatever number comes back. But scrap metal prices today vary dramatically by metal type — copper can fetch ten times more per pound than steel. If you can't identify what you're hauling, you're negotiating blind.
This guide gives you two simple tools — your eyes and a magnet — to sort your load before you sell. Whether you're clearing out a workshop in Moncton, stripping a demo site in New Brunswick, or just picking up odds and ends from the curb, knowing what you have puts you in a stronger position. And a stronger position means a better price.
You don't need a lab. You need a $2 magnet and five minutes.
The Magnet Test: Your First and Fastest Sort
Before you do anything else, run a magnet across your pile. This single step divides every piece of metal into two categories: ferrous (iron-based, sticks to magnet) and non-ferrous (everything else, doesn't stick). That distinction matters more than almost anything else when it comes to pricing.
Ferrous metals — steel, cast iron, wrought iron — are magnetic and generally lower value. They're priced by the ton and sold in bulk. Non-ferrous metals — copper, aluminum, brass, stainless steel, lead, zinc — are non-magnetic, lighter, and almost always worth significantly more per pound. Separating these two groups before you arrive at the yard means faster sorting on arrival and, often, better offers.
Here's how the magnet test breaks down:
- Strong magnet pull → ferrous metal (steel, iron, tin-coated steel)
- Weak or no pull → likely non-ferrous (copper, aluminum, brass, lead)
- Slight pull, inconsistent → could be stainless steel (some grades are mildly magnetic)
- No pull, very heavy → likely lead
- No pull, lightweight and dull grey → likely aluminum
The magnet doesn't tell you everything, but it narrows the field fast. From there, your eyes take over.
Visual Identification Guide: Metal by Metal
Once you've sorted magnetic from non-magnetic, use color, weight, and surface texture to get more specific. Each metal has visual cues that, once you know them, become second nature.
Copper
Copper is one of the most valuable metals in any scrap pile. Fresh copper is a distinct reddish-orange. Aged or oxidized copper turns greenish (called patina or verdigris). You'll find it in electrical wire, plumbing pipe, roofing material, and motor windings. Heavy for its size, non-magnetic, and often shiny when cut fresh — copper is hard to mistake once you know what you're looking at. Stripping insulation from copper wire can meaningfully increase its value; bare bright copper commands the top end of copper price Canada market rates.
Aluminum
Aluminum is lightweight, silver-grey, and non-magnetic. It doesn't rust — it oxidizes into a dull, chalky white coating. You'll find it in window frames, car rims, siding, cans, and engine blocks. It's significantly lighter than steel or copper of the same size. If you can lift a piece easily that looks like it should be heavy, there's a good chance it's aluminum. Aluminum price Canada rates vary depending on grade — cast aluminum (engine blocks, wheels) prices differently than extruded aluminum (frames, sheets).
Brass
Brass is a copper-zinc alloy with a distinct yellow-gold color, darker than gold itself. Non-magnetic, heavier than aluminum, and commonly found in plumbing fittings, valves, faucets, shell casings, and decorative hardware. Aged brass often takes on a dull, brownish tint. Scratch the surface — if it reveals that yellow-gold underneath, it's brass. It's worth considerably more than steel and typically falls between copper and aluminum in value.
Stainless Steel
Stainless steel is silver-coloured, resistant to rust, and heavier than aluminum. Some grades are weakly magnetic — a key differentiator from other non-ferrous metals. You'll find it in kitchen appliances, cookware, exhaust systems, and food processing equipment. It holds its shine under normal conditions and is noticeably harder to scratch than aluminum. Steel price Canada rates for stainless are higher than regular steel but lower than copper or brass.
Cast Iron and Steel
Both are magnetic and heavier than most metals pound-for-pound. Cast iron is brittle, rough-textured, and often has a grey or black surface. Steel is smoother, more flexible, and found in structural components, appliances, car bodies, and rebar. Regular steel is priced by weight in bulk — it's the workhorse of ferrous recycling but won't get you the per-pound numbers that copper or brass will.
Lead
Lead is non-magnetic, very heavy for its size, and has a dull grey surface that leaves a grey mark when scratched against paper. You'll find it in old pipes, fishing weights, wheel balance weights, and battery plates. Handle it carefully — lead is a health hazard. It commands a solid price per pound and is easy to identify once you know how dense it feels in your hand.
How Scrap Metal Prices Today Reflect Metal Grade and Cleanliness
Knowing the metal type is step one. Knowing how yards price it is step two. Scrap metal prices today aren't just tied to metal type — they're also driven by condition, cleanliness, and how much processing the yard has to do after you drop it off.
A mixed load gets priced at the lowest common denominator. A sorted, clean load gets individual line items for each metal — and those add up fast. Here's what buyers look for:
- Copper wire: Bare bright (stripped) versus insulated — significant price gap between the two
- Aluminum: Cast versus sheet versus extrusion — different grades, different prices
- Brass: Clean yellow brass versus mixed brass versus dirty brass with soldered attachments
- Steel: Heavy melt versus light iron versus shredder steel — all priced differently
- Contamination: Rubber, plastic, paint, oil — all reduce the offer, sometimes significantly
The more work you do before the yard, the less margin they need to build in for sorting and processing. That savings gets reflected back to you — at least it should when you're selling competitively. To find the best Canadian scrap metal prices today, you need more than one buyer looking at your load.
Why Sellers in Moncton and New Brunswick Should Think Beyond One Buyer
Here's the part most local sellers don't think about: the price a single yard quotes you is not necessarily the market price. It's what that one buyer is willing to pay today. There's a reason yards don't advertise their buy prices prominently — limited information benefits the buyer.
Sellers in Moncton have access to local yards, which is fine for small loads and quick turnarounds. But for larger loads — a truckload of copper, a pile of sorted non-ferrous, a batch of cats and cores — getting one quote means you're leaving competitive pricing on the table. Moncton scrap metal services connect local sellers with the broader buyer network, not just whoever picks up the phone first.
This is exactly where platforms like SMASH change the equation. smashrecycling.ca connects vetted sellers with multiple buyers through a competitive auction format — no subscription fees, no guessing. More buyers looking at a documented, sorted load means better price discovery. The yard model works for convenience. The auction model works for value.
SMASH supports photo documentation, serial tracking, and proper inventory tools so buyers know exactly what they're bidding on. A clean, well-documented load of sorted copper or aluminum generates real competition — and real competition reveals the actual market. You can also check current Canadian scrap metal prices before you list anything, so you walk in with context instead of guessing.
If you're in New Brunswick and moving more than scrap-bucket quantities, it's worth knowing your options before your next sale. To understand how pricing works across different metals and regions, read Canadian scrap metal pricing guides and go in prepared.

Bookmark this before your next demo or cleanout run. A fast visual reference for common metals you'll encounter on a job site or in a shop:
- Copper — Reddish-orange, heavy, non-magnetic. Turns green with age. High value.
- Aluminum — Silver-grey, lightweight, non-magnetic, no rust. Moderate value.
- Brass — Yellow-gold, heavy, non-magnetic. Found in fittings and hardware. Good value.
- Stainless steel — Shiny silver, heavy, slightly or weakly magnetic, rust-resistant. Moderate value.
- Lead — Very heavy, dull grey, non-magnetic, leaves grey mark when scratched. Good value per pound.
- Cast iron — Rough grey surface, heavy, strongly magnetic, brittle. Lower value, priced by volume.
- Mild steel — Smooth, magnetic, can rust. Structural applications. Lower value, bulk priced.
- Zinc — Bluish-grey, non-magnetic, often found as die-cast parts. Moderate value.
Sort before you sell. Label your loads. Document with photos when the volume justifies it. These small steps consistently produce better outcomes than showing up with a mixed pile and hoping for the best.
When you're ready to move a load, don't settle for the first number you hear. The best Canadian scrap metal prices come from competition, not convenience — and that starts with knowing exactly what you have.

Frequently Asked Questions
Q: How do I tell copper from brass without a magnet?
Color is your best guide. Copper has a distinct reddish-orange tone, while brass is more yellow-gold. Scratch the surface of a questionable piece — copper shows red-orange underneath, brass reveals yellow. Both are non-magnetic and heavier than aluminum.
Q: What scrap metal prices today should I expect for aluminum in Moncton?
Aluminum prices vary by grade and market conditions — cast aluminum and sheet aluminum price differently. Prices also shift with commodity markets, so what was accurate last month may not reflect today's rate. Always check current pricing before selling rather than relying on old quotes.
Q: Is stainless steel worth selling as scrap in New Brunswick?
Yes — stainless steel commands a higher price than regular mild steel or cast iron. It prices differently from non-ferrous metals like copper or brass, but it's worth separating from your ferrous pile. Larger volumes fetch better rates, so accumulate before selling if possible.
Q: How does SMASH differ from selling at a local scrap yard near me?
A local yard gives you one price from one buyer. SMASH uses a competitive auction format where multiple vetted buyers bid on your load — meaning price discovery happens through competition, not a single quote. There are no subscription fees; SMASH earns only when the seller does.
Q: Does cleaning and sorting metal before selling actually make a difference in price?
Yes — significantly. Yards price mixed or contaminated loads at the lowest grade in the pile. Sorted, clean metals get individual pricing, and each category is evaluated on its own merits. Stripping copper wire, separating aluminum grades, and removing attachments from brass all directly impact what you're offered.
