Most people selling aluminum scrap leave money on the table — not because buyers are dishonest, but because sellers don't know what they're actually holding. Aluminum isn't just aluminum. Grade matters. Contamination matters. And how you present your load matters more than most yards will ever tell you.
If you want to stop guessing and start getting paid what your material is actually worth, this guide breaks down aluminum scrap grades, what separates a top-dollar load from a discounted one, and how platforms like sell your scrap metal on SMASH Recycling are changing the way sellers across Canada get competitive offers — without the runaround.
And yes — even if you're tracking the steel scrap price today, understanding aluminum grades makes you a smarter seller across every material you move.
Why Aluminum Grade Is the First Thing Buyers Look At
Walk into any yard with a mixed pile of aluminum and you'll get a blended price — and not in your favour. Yards sort it themselves and pocket the spread. That's not a conspiracy; it's just business. The way to protect yourself is to know your grades before you show up.
Aluminum scrap broadly falls into two categories: clean and contaminated. Clean aluminum has no paint, plastic, rubber, iron, or other metals attached. Contaminated aluminum — think aluminum extrusions with plastic end caps, or rims with steel valve stems — gets docked immediately. The bigger the dock, the worse your return.
Here's a quick breakdown of the most common aluminum grades you'll encounter:
- 1100 / Pure Aluminum Sheet (Clip): Clean, uncoated aluminum sheet. High purity. Commands top prices.
- Cast Aluminum: Engine blocks, manifolds, transmission housings. Dense, heavy, usually dirty — priced lower per pound but valuable in volume.
- Aluminum Extrusions (6061/6063): Window frames, door frames, ladder rails. Clean extrusions are a solid mid-tier grade.
- MLC (Mixed Low Copper Aluminum): A blended grade — various alloys, some painted. Common from demolition and manufacturing waste.
- Aluminum Rims: Chrome-free steel-free rims fetch strong prices. Chrome-plated or steel-insert rims get docked.
- Aluminum Cans (UBC — Used Beverage Containers): Clean, light, high volume. Recyclers deal in these by the bale or pound.
- Turnings: Machine shop waste — aluminum shavings and chips. Often contaminated with cutting fluids. Prices vary widely based on oil content.
- Old Sheet Aluminum: Painted or anodized. Lower grade than clean clip. Common from roofing and siding teardowns.
The difference between getting paid for "clean extrusion" versus "mixed aluminum" can be significant. Know which one you have before the buyer decides for you.
How to Prepare Your Aluminum Scrap for Maximum Value
Preparation isn't just about looking professional — it directly affects what you get paid. A clean, sorted, well-documented load gives buyers more confidence. More buyer confidence means stronger offers, especially in a competitive auction environment where buyers are bidding against each other, not just making you a take-it-or-leave-it offer.
Here's what separates a high-value aluminum load from a discounted one:
- Sort before you sell. Don't mix cast with extrusion. Don't throw rims in with sheet. Each grade should be separated. Mixed loads get priced at the lowest common denominator.
- Remove steel and iron. Steel bolts, brackets, and inserts are the fastest way to kill your aluminum price. Pull them out. A magnet is your best prep tool.
- Degrease your turnings. Wet or oily turnings get heavily discounted. If you're moving machine shop material regularly, ask about centrifuging or draining options.
- Document with photos. Serious buyers want to see what they're bidding on. Photo documentation — clear shots of each grade, weight tickets, packing lists — builds credibility and speeds up transactions.
- Weigh it accurately. Know your weights before you go. Buyers who trust your numbers trust you. That trust compounds over time.
For Scarborough-area sellers moving regular volumes of aluminum — whether from renovation waste, manufacturing trim, or auto parts — this prep work pays off every single time. It also positions you to use competitive platforms rather than defaulting to whoever happens to be nearby.
Scrap Metal Prices Today: What Moves Aluminum Values
Aluminum prices don't move in isolation. They track the London Metal Exchange (LME), North American regional premiums, and local supply-demand dynamics — all at once. On any given day, the scrap metal prices today for aluminum could shift based on energy costs, smelter capacity, import/export dynamics, or even currency fluctuations between CAD and USD.
What this means practically: the price you got six months ago is not the price you'll get today. And the price one yard quotes you today is not necessarily the market price — it's their buying price, which includes their margin.
Key factors that push aluminum scrap prices up or down:
- LME aluminum spot price: The global benchmark. Yards price off this plus or minus a local premium.
- Grade quality and contamination level: Directly impacts what you receive per pound.
- Volume: Larger, consistent loads get better rates. A one-time 200 lb drop-off gets a different price than a weekly 2,000 lb delivery.
- Buyer competition: One buyer means one price. Multiple buyers competing means market discovery. That's the core argument for auction-based selling.
- Regional supply: A spike in local demolition or manufacturing scrap can suppress prices temporarily in markets like Scarborough or elsewhere in Ontario — or drive them up if buyers are short on material.
The same logic applies if you're monitoring the steel scrap price today — knowing what drives prices gives you leverage in every conversation with a buyer, whether you're selling ferrous or non-ferrous material.

Why Single-Buyer Deals Cost You Money (And What to Do Instead)
Here's the uncomfortable truth about the old way of selling scrap: calling one buyer, getting one price, and accepting it because you don't know if it's fair. That's not a negotiation. That's a coin flip weighted against you.
The B2B scrap metal marketplace model exists because competition creates transparency. When multiple vetted buyers are looking at your load and placing offers, you see where the market actually sits — not where one buyer wants it to sit. That difference can be meaningful, especially on high-value non-ferrous material like clean aluminum extrusions, UBC, or automotive aluminum castings.
Platforms built on the auction model — like the SMASH scrap metal auction — give sellers access to a network of buyers who compete for loads. No subscription fees. No commitment to a single buyer relationship that may or may not be serving you. You post your material with documentation, buyers bid, and you make an informed decision about whether to accept. It's not magic — it's just how markets should work.
If you're in Scarborough or anywhere else in Ontario and you've been defaulting to the same yard for years without knowing if you're getting fair value, it's worth testing the market at least once. You might be surprised.
You can sell your scrap metal in Canada on SellYourScrap and connect with buyers who are actually competing for your material — rather than making a quiet offer and hoping you take it.
How SMASH Helps Sellers Get Fair Value on Aluminum Loads
SMASH isn't a yard. It's not a broker pretending to be neutral. It's a platform that puts your documented load in front of vetted buyers and lets the market respond. For aluminum sellers — especially those moving consistent volumes — that structure matters.
Here's what the SMASH process does differently:
- Inventory documentation: Weights, photos, grade descriptions, and packing lists are part of the listing. Buyers know what they're bidding on. Less ambiguity means stronger offers.
- Vetted buyer network: You're not dealing with whoever shows up. Buyers on the platform are verified, which reduces the friction and risk of bad transactions.
- Auction format: Competition drives price discovery. More buyers means better price discovery — especially on premium grades like clean extrusion or automotive cast aluminum.
- Auto-invoicing: When a deal closes, paperwork is handled. BOLs, invoices, and documentation flow automatically, reducing admin time for yards and individual sellers alike.
- No subscription fees: SMASH wins when you win. That alignment matters.
Whether you're a one-person renovation crew in Scarborough moving a truckload of aluminum window frames, or a mid-sized Ontario yard looking to move specialty non-ferrous material to the right buyer, the platform is built to handle both ends of that spectrum.
If you want to get a fair price for your scrap today, start by documenting what you have and letting buyers compete for it. That's the whole model.

Frequently Asked Questions
Q: What is the difference between cast aluminum and extruded aluminum scrap?
Cast aluminum comes from poured molds — engine blocks, manifolds, automotive housings. It's dense but often contaminated with other metals or coatings. Extruded aluminum (like 6061 or 6063) is formed by pushing aluminum through a die — think window frames, door frames, and ladder rails. Clean extrusions typically fetch a higher price per pound than cast, because the alloy is more consistent and easier for smelters to process.
Q: How do I find the best scrap metal prices today in Scarborough?
Start by sorting and documenting your aluminum grades before you approach any buyer. A sorted, clean load with accurate weights gives you a credible position in any price conversation. Then compare offers — don't accept the first one. Platforms like SMASH allow you to put your load in front of multiple vetted buyers, which helps reveal where the market actually sits in your region, including Scarborough and the broader Ontario market.
Q: Does the steel scrap price today affect aluminum scrap prices?
Not directly — steel and aluminum track different markets and benchmarks. Steel prices follow ferrous indices, while aluminum tracks the LME. However, broader industrial and economic conditions that move steel prices often affect non-ferrous metals as well. If you're selling both ferrous and non-ferrous material, monitoring both markets helps you time larger loads more effectively.
Q: What's the fastest way to sell scrap metal near me in Ontario?
Sort your material, photograph it, weigh it, and post it with accurate documentation. Buyers move faster when they trust what they're looking at. Local yards are always an option for small loads, but for anything over a few hundred pounds, putting it into a competitive marketplace gives you better visibility and often better returns. If you're in Ontario, SellYourScrap.ca connects you with buyers who are actively looking for material.
Q: Can individuals sell aluminum scrap through a B2B scrap metal marketplace, or is it only for businesses?
Most B2B platforms are designed for yards and businesses moving consistent volumes, but individuals with significant loads — a full truck of aluminum extrusions from a demolition, for example — can absolutely benefit from competitive offers rather than a single yard quote. If you're unsure whether your volume qualifies, reach out directly and ask. The worst answer is "not quite yet," and even then you'll learn what threshold makes competitive selling worth it.
If you've been sitting on aluminum scrap and defaulting to whoever's closest, it's worth asking whether that's actually the best deal — or just the easiest one. Sorting your grades, documenting your load, and letting buyers compete takes a bit more effort upfront. But it's the difference between guessing and knowing.
