Why the Grade of Your Aluminum Determines the Price You Get
Most scrap sellers leave money on the table — not because they sold at the wrong time, but because they didn't know what grade their aluminum was. The aluminum scrap price today isn't a single number. It's a spectrum. A clean sheet of 6061 aluminum alloy and a painted extrusion from an old window frame do not fetch the same rate, even at the same scrap yard on the same day. If you're hauling metal without sorting it first, you're almost certainly getting paid the lowest possible price for the highest-quality material in your load.
This guide breaks down aluminum scrap grades, what buyers look for, and how sellers in Thunder Bay and across Ontario can position themselves to earn top dollar every time they sell. Whether you're a contractor clearing a job site, a homeowner clearing out a garage, or a regular scrapper with a full truck, understanding aluminum grades changes everything.
Understanding Aluminum Scrap Grades: What Buyers Actually Pay For
Aluminum scrap is broadly divided into two main categories: clean aluminum and contaminated or mixed aluminum. Within those categories, buyers use a more detailed grading system to assign value. The cleaner and more uniform your material, the higher the payout per kilogram.
Here are the most common aluminum grades you'll encounter as a scrap seller in Canada:
- Clean aluminum extrusions (6061, 6063): Window frames, door frames, and architectural profiles — without paint, rubber, or hardware attached. This is one of the higher-value grades.
- Cast aluminum: Engine blocks, transmission cases, wheels — heavier and denser than sheet, but buyers discount for grease or steel inserts.
- Sheet aluminum (clean): Flat sheet or coil stock with no oil, paint, or plastic attached. Consistently valued due to its purity.
- Aluminum wire (insulated): Valued by copper content percentage, not aluminum weight — a common confusion for first-time sellers.
- Mixed aluminum (dirty): Painted, coated, or mixed with other metals. This grade receives a significant discount — sometimes 30–50% less than clean equivalents.
- Aluminum cans (UBC — Used Beverage Containers): A separate and recognizable category. High volume, moderate value, easily recyclable.
- Breakage / irony aluminum: Aluminum with significant iron content — the lowest grade, often separated and priced near steel rates.
Knowing which category your material falls into before you arrive at a facility — or before you list it online — gives you negotiating power and realistic expectations. Platforms like smashrecycling.ca allow sellers to describe their material accurately and connect with buyers who pay fair, competitive rates by grade.
How to Prepare Your Aluminum to Get the Best Scrap Metal Prices in Thunder Bay
Preparation is the single highest-leverage action you can take before selling. A few minutes of sorting can mean a meaningful difference in what ends up in your pocket. Scrap facilities in Thunder Bay — and across Ontario — grade and weigh your material on arrival. If your clean extrusions are bundled with painted pieces or mixed with hardware, the entire load gets downgraded.
Follow these steps to maximize what you receive:
- Separate by alloy type where possible. Mixed aluminum alloys get blended pricing. Clean, single-alloy loads command a premium.
- Remove non-aluminum attachments. Take off screws, bolts, rubber gaskets, and plastic end caps from window frames and extrusions. Five minutes of work can significantly upgrade your grade classification.
- Degrease cast aluminum. Engine blocks and pistons with heavy oil contamination are discounted. A rinse or wipe-down can help, but some facilities have minimum standards for oil content.
- Keep cans separate. UBC cans have their own pricing category. Mixing them with extrusions or sheet dilutes both loads.
- Bundle or bale where you can. Loose, awkward material takes more time to process. Neat bundles show a buyer you know your product — and serious sellers often get better treatment at the scale.
If you're unsure how a facility will grade your specific material, call ahead. Better yet, use a platform where you can describe the material and receive offers before you load up the truck.

Reading the Market: What Drives the Aluminum Scrap Price Today
The aluminum scrap price today doesn't exist in isolation. It tracks the London Metal Exchange (LME) aluminum price, adjusted for local demand, transportation costs, and the specific grade of metal you're selling. In mid-2026, aluminum continues to see solid demand driven by EV manufacturing, packaging, and construction — all sectors where lightweight metals are non-negotiable.
Several factors will affect what you receive on any given day:
- LME primary aluminum price: This is the global benchmark. When primary aluminum prices rise, scrap premiums typically follow — with a short lag.
- Local demand in Ontario: Secondary smelters and die-casters in Ontario's industrial corridor drive strong regional demand for clean scrap, particularly cast and extrusion grades.
- Export activity: Canadian scrap aluminum is exported to the U.S. and overseas markets. Strong export demand tightens local supply and lifts prices. Watch for shifts in U.S.–Canada trade conditions, which in 2026 remain an active factor in cross-border scrap flows.
- Seasonal patterns: Construction and renovation activity picks up in spring and summer across Northern Ontario, including Thunder Bay — increasing aluminum scrap supply from job sites and, typically, keeping prices competitive.
- Fuel and freight costs: For sellers in Thunder Bay, transportation distance to major processors is a real factor. Getting accurate local pricing matters more here than in larger urban centres.
Staying informed means tracking prices regularly — not just checking once before a big load. To check current Canadian scrap metal prices and monitor how aluminum grades are trending, bookmark a reliable pricing resource and compare at least two buyers before committing your load.
Selling Scrap Aluminum in Thunder Bay: Getting the Local Advantage
Thunder Bay sits in a unique position for scrap metal sellers. It's a major centre for Northwestern Ontario — drawing material from the surrounding region while also sitting at a logistical crossroads between Western and Central Canada. Local scrap yards serve a broad community of contractors, miners, and manufacturers, which means consistent demand for non-ferrous metals including aluminum.
That said, competition between buyers in smaller markets can be less intense than in Toronto or Hamilton. This makes it even more important to get multiple quotes rather than defaulting to the nearest facility. Sellers using Thunder Bay scrap metal services through a platform like SMASH can access competitive bidding rather than accepting a single posted rate. If your load is large enough, the difference in offers from multiple buyers can be substantial — sometimes enough to justify the effort of a phone call or online listing.
SMASH — the Scrap Metal Auction Sales Hub — was built specifically to give Canadian sellers, including those in Northwestern Ontario, access to multiple buyers and transparent pricing. Rather than guessing whether the price a local yard quotes is fair, you can put your material in front of multiple buyers and let the market decide. For Thunder Bay scrap metal services, SMASH provides a direct connection to buyers who understand the local and national market.

Common Mistakes That Cost Aluminum Sellers Money
Even experienced scrap sellers make avoidable errors that reduce their payout. Here are the most common pitfalls — and how to sidestep them:
- Not sorting before arriving: Mixed loads get blended at the lowest grade. Ten minutes of sorting at home outperforms an hour of arguing at the scale.
- Accepting the first price offered: The first quote is rarely the best. Getting multiple offers is standard practice for anything above a few hundred kilograms.
- Ignoring grade terminology: If a buyer says "painted extrusion" or "dirty cast," they mean a lower price. Learn the terms so you can challenge a downgrade if your material genuinely qualifies for a better grade.
- Selling at low-volume prices regularly: If you accumulate material over time and sell large loads periodically, you often qualify for better per-kilogram rates. Frequency sellers who show up with small loads repeatedly miss volume pricing.
- Not tracking the market: Selling aluminum when prices are at a seasonal low because you didn't check the trend costs real money. It takes five minutes to look up current rates — use them.
The aluminum scrap price today in Canada rewards informed sellers. Those who know their grades, prepare their material, and compare multiple buyers consistently outperform those who simply show up and accept whatever's offered.

Frequently Asked Questions
Q: What is the aluminum scrap price today in Thunder Bay?
Aluminum scrap prices in Thunder Bay vary by grade, volume, and current LME aluminum rates. Clean extrusions and cast aluminum typically command higher rates than painted or mixed material. Prices change daily, so check current rates through a live pricing platform rather than relying on posted rates that may be outdated.
Q: How do I find the best scrap metal prices near me in Ontario?
The most reliable approach is to compare at least two or three buyers before committing your load. Platforms like SMASH allow you to list your material and receive competitive offers from multiple buyers — rather than accepting a single posted rate from one local yard. For sellers across Ontario, this often results in meaningfully better payouts.
Q: What aluminum grades pay the most at scrap yards?
Clean, uncontaminated material consistently pays the most. Top grades include clean 6061 and 6063 extrusions (no paint or hardware), clean sheet aluminum, and clean cast aluminum with no steel inserts or heavy oil. Removing attachments and sorting by type before arrival is the single fastest way to improve your payout.
Q: Can I sell scrap aluminum online in Canada?
Yes. Platforms designed for the Canadian market — including SMASH — allow you to list your scrap material online, receive offers from multiple buyers, and arrange pickup or drop-off. Selling scrap metal online gives you access to buyers beyond your immediate local area, which is particularly valuable for sellers in Northwestern Ontario where local buyer competition may be limited.
Q: Is it worth separating aluminum from other metals before selling?
Absolutely. Separating aluminum from steel, copper, and other metals before you sell ensures each material is priced at its correct value — not blended down to a mixed-metal rate. Keeping non-ferrous metals like aluminum separate from ferrous metals (steel, iron) is one of the most impactful steps any scrap seller can take to improve their total payout.
If you're ready to stop leaving money on the table, start by knowing your grades, preparing your material, and comparing offers. Whether you're running a regular route in Thunder Bay or clearing out a one-time renovation project anywhere in Ontario, the right information gets you the right price. Find the best Canadian scrap metal prices today and see what your aluminum is actually worth on the current market.
