Most sellers leave money on the table before they even load the truck. They haul mixed aluminum to the yard, take whatever they're offered, and call it a day. But aluminum isn't one thing — it's dozens of grades, and each one pays differently. Knowing the difference between clean sheet aluminum and dirty cast can mean a significant jump in what you walk away with.
This guide breaks down aluminum scrap grades, explains what buyers actually look for, and shows you how to prep your material to get the best return. Whether you're clearing out a shop in Hamilton or moving regular loads across Ontario, this is how you stop leaving cash on the table.
And while aluminum is the focus here, savvy recyclers track everything — including the copper scrap price today — because knowing your metals means knowing your money.
Why Aluminum Grade Matters More Than You Think
The scrap market doesn't pay a flat rate for aluminum. It pays based on what buyers can actually do with the material. A clean, uncontaminated grade of aluminum is easier to process, easier to smelt, and worth more per pound. Mixed or contaminated loads create extra work — and the yard passes that cost straight back to you in the form of a lower price.
Consider the spread between common grades. Clean aluminum extrusion (think window frames, door frames, and structural profiles) typically trades higher than painted or coated aluminum. Dirty aluminum — mixed with steel hardware, rubber, or other contaminants — can price out significantly lower per pound. That spread isn't trivial when you're moving hundreds of pounds at a time.
The lesson: sorting aluminum before you go to the yard isn't extra work. It's the work. Done right, it's also the most reliable way to increase your payout without hauling more material.
The Most Common Aluminum Scrap Grades Explained
Understanding what each grade actually means puts you in control of the conversation at the scale. Here are the grades you'll encounter most often:
- Clean Aluminum Extrusion: Window frames, door frames, heat sinks, structural profiles. No steel inserts, no paint (or minimal paint). This is a premium grade and prices accordingly.
- Aluminum Sheet (Irony or Clean): Roofing sheets, siding, HVAC panels. "Clean" means minimal contamination. "Irony" means it has steel rivets, bolts, or backing — and prices lower as a result.
- Cast Aluminum: Engine blocks, transmission housings, pump housings. Heavier and denser than sheet. Pays well when clean. Often collected from automotive and industrial teardowns.
- Aluminum Rims (Auto): Passenger car wheels. A steady, well-defined grade. Buyers know exactly what they're getting and price accordingly. Remove the rubber and steel valve stems first.
- Aluminum Cans: The most recognizable grade. UBC (Used Beverage Cans) is a defined commodity grade. Volume matters here — per-pound rates are real but you need quantity to make it worthwhile.
- Dirty Aluminum / Mixed Aluminum: Anything you haven't sorted. Multiple alloys, attached steel, rubber, plastic, or heavy contamination. Yards will buy it, but at the lowest rate in the aluminum category.
- Aluminum Wire: Electrical wiring stripped from buildings or equipment. Can grade as clean or insulated depending on prep. Strip it if the math works in your favor.
- Breakage / Aluminum Clip: New or clean production scrap from manufacturing. Off-cuts, stampings, and punchings. Often the cleanest aluminum available and prices as such.
Most yards in Hamilton and across Ontario sort broadly into two or three aluminum tiers at the scale. But the more clearly you can communicate — and document — what you have, the more leverage you carry in the pricing conversation.
How to Prep Aluminum for Maximum Payout
Preparation is where the real money is made. A few hours of sorting can meaningfully shift your per-pound rate. Here's what actually moves the needle:
- Remove steel hardware. Bolts, screws, hinges, inserts — anything ferrous pulls your aluminum into a lower grade. A magnet is your best tool here. If it sticks, pull it out.
- Separate by alloy type where possible. Cast and extrusion don't belong in the same pile. Rims should be separate from sheet. Clean separation is how you access the higher price tiers.
- Pull out the non-aluminum contaminants. Rubber seals, plastic clips, wiring, and insulation all count against your material. Strip what you can. Discard what you can't salvage.
- Photograph your loads. This matters more than most sellers realize. If you're selling through a platform or have to dispute a yard's grade call, documented photos of your sorted material give you something to stand on. Platforms like SMASH build photo documentation into the sale process for exactly this reason.
- Weigh before you go. A rough scale reading at your shop gives you a baseline. It's not a guarantee, but it keeps you from being caught completely off guard at the yard scale.
- Label or tag mixed loads clearly. If you're moving multiple grades in one truck, keep them physically separated and labelled. Commingled loads get priced at the lowest common denominator.
These steps apply whether you're running a small operation out of Hamilton or managing larger volumes across the province. The discipline of sorting compounds — it gets faster, and the payouts get more predictable.
Scrap Metal Prices Today: Aluminum vs. Copper and Why You Should Track Both
Aluminum prices move with global commodity markets, energy costs, and manufacturing demand. So does copper. Smart recyclers don't just track one metal — they track the spread between them, because it shapes which loads are worth chasing and which contracts are worth taking.
The copper scrap price today is typically several times higher per pound than aluminum, which makes copper the headline metal for most yard operators. But aluminum volume can make up the difference at scale, and certain aluminum grades — clean extrusion, aluminum clip, automotive cast — price closer to copper than you might expect when sorted properly.
Check today's Canadian scrap metal prices before you commit to a sale. Rates shift. What one yard pays today may differ from what another offers tomorrow. In markets like Hamilton and across Ontario, local competition between buyers also affects real transaction prices — and that competition is something you can use.
Platforms like SMASH are built on that principle. Put your documented aluminum load in front of multiple vetted buyers simultaneously, and let market competition — not a single buyer's morning mood — set the price. That's how price discovery is supposed to work. To read the latest Canadian scrap metal market updates, bookmark the blog and check it before you move any significant load.
The Role of Documentation in Getting Better Aluminum Prices
Most sellers skip documentation entirely. That's a mistake — especially on higher-value loads. Buyers price uncertainty into their offers. If they can't see what they're buying until the load shows up, they build a buffer into the quote. That buffer comes out of your pocket.
Good documentation for an aluminum load includes:
- Clear photos of the sorted material by grade
- An estimated weight or weigh ticket from your facility
- Notes on any known contaminants or prep done (e.g., "steel inserts removed from extrusion")
- Grade descriptions using standard industry terminology
When buyers have real information, they compete more aggressively. When they're guessing, they protect themselves with a lower offer. This is the core logic behind why finding current Canadian scrap metal prices through a transparent platform beats taking a single blind quote every time. For local sellers using Hamilton scrap metal services, good documentation means you show up to every transaction ready to support your own grade call.
Getting the Most From Your Aluminum Loads in Hamilton and Ontario
Hamilton has a strong base of scrap buyers and yards, which creates real competition if you know how to work it. Ontario's industrial corridor — automotive plants, manufacturing facilities, construction sites — generates consistent aluminum scrap volume. That supply keeps the market liquid, but it also means buyers have options. Your edge is preparation, documentation, and access to multiple buyers simultaneously.
The old approach — one call, one quote, take it or leave it — doesn't reflect what scrap metal prices today actually look like in a competitive market. Whether you're selling aluminum rims off a teardown in Hamilton, moving clean extrusion from a renovation project, or liquidating cast aluminum from a decommissioned facility, you deserve to know the real market price before you accept anything.
Track scrap metal prices today, sort your aluminum by grade, document your loads, and bring real competition into the transaction. That's how you stop guessing and start selling on your terms. When you're ready to move a significant load, platforms like SMASH connect you with vetted buyers across North America — no subscription required, no guessing involved.

Frequently Asked Questions
Q: What is the copper scrap price today in Canada?
Copper scrap prices change daily based on global commodity markets, local supply, and buyer competition. The best approach is to check today's Canadian scrap metal prices directly for current rates in your region. Never rely on a quote from a week ago — copper moves fast.
Q: How do I know what grade my aluminum is?
Start with a visual and magnetic check. If a magnet sticks to it, it's not aluminum — or it has steel contamination. From there, look at the form: extrusion profiles, sheet, cast housings, wire, and cans are all visually distinct. When in doubt, your yard can help identify grades at the scale, but going in informed gives you more leverage on the price.
Q: Are scrap metal prices in Hamilton different from other Ontario cities?
Prices can vary between yards and regions based on local buyer competition, transportation costs, and demand. Hamilton's industrial base means active buyers, but it's always worth comparing offers. Using a multi-buyer platform gives you a clearer picture of what the market will actually pay versus what one local yard is offering that day.
Q: Does cleaning and sorting aluminum really make a difference in the price I get?
Yes — consistently. Contaminated or mixed aluminum gets priced at the lowest grade in the mix. Removing steel hardware, separating cast from extrusion, and keeping grades clean can meaningfully increase your per-pound rate. The time invested in sorting pays back in the payout at the scale.
Q: What is the best way to sell large aluminum loads in Ontario?
Document your load with photos and weight estimates, sort by grade, and bring it to multiple buyers simultaneously rather than taking a single quote. Platforms like SMASH let vetted buyers compete for your load, which means better price discovery and a more transparent transaction than a single cold call to one yard. No subscription fees — they only earn when you do.
