Most people treat scrap metal like it's all the same pile. It's not. Steel and iron look similar, weigh the same, and both stick to a magnet — but they price out very differently at the yard. If you're hauling loads without knowing the difference, you're probably leaving money on the table.
This guide breaks down what separates steel from iron scrap, why the price gap exists, and how that knowledge applies whether you're clearing a job site in Baltimore or selling a mix of metals from a renovation. We'll also touch on where aluminum scrap price today fits into the bigger picture — because non-ferrous pricing gets its own rules entirely.
Steel vs. Iron: What's Actually Different?
Both steel and iron are ferrous metals — they contain iron as the base element. But that's roughly where the similarity ends. Cast iron is a brittle, high-carbon alloy. Think engine blocks, old radiators, wood stove bodies, manhole covers, and vintage cookware. It's dense and heavy, but it fractures instead of bending.
Steel is a refined alloy with less carbon than cast iron. It's more malleable, more versatile, and more widely used in modern construction and manufacturing. Most structural beams, rebar, pipes, car frames, and appliances are steel. Because steel dominates modern industry, there's a massive, liquid recycling market for it — which directly affects how it prices at the yard.
Here's the practical breakdown:
- Cast iron — heavy, brittle, high-carbon, typically prices slightly higher per pound than mixed steel scrap due to its density and specific remelting uses
- Wrought iron — rare in modern scrap, low-carbon, highly malleable; mostly found in older decorative fencing and railings
- Structural steel / HMS (Heavy Melting Steel) — the most common category; includes beams, plate, heavy pipe, and car bodies
- Light gauge steel — sheet metal, thin-wall tubing, appliance shells; prices lower than HMS because mills need to process more volume
- Stainless steel — different category entirely; contains nickel and chromium and commands a significantly higher price than carbon steel
Understanding these categories isn't trivia. Every time you sort your load correctly, you're negotiating with the yard using real information instead of guessing.
Why the Price Gap Exists Between Steel and Iron Scrap
The price difference between cast iron and various grades of steel comes down to mill demand, processing cost, and chemistry. Steel mills buying ferrous scrap care deeply about metallurgical consistency. A load of clean HMS1 (heavy melting steel, no gauge requirement under a quarter inch) is predictable. A mixed load of cast iron, mystery metal, and light gauge introduces variables mills don't want to pay for.
Cast iron, specifically, requires different furnace settings when it's remelted. It's not bad scrap — it's just specialized. Foundries that produce new castings want clean iron. Steel mills making structural product don't. That narrower buyer pool tends to suppress cast iron prices compared to what clean structural steel fetches in active markets.
The other driver is global steel demand. When construction activity in the U.S. is high, HMS prices rise because mills are buying more scrap to feed electric arc furnaces. When demand drops — due to slower housing starts, reduced infrastructure spending, or import competition — ferrous prices follow. Cast iron pricing moves in the same direction but doesn't always track at the same rate.

Where Aluminum Scrap Price Today Fits Into Your Selling Strategy
You're probably wondering: why does an article about steel and iron mention aluminum scrap price today? Because most real-world loads are mixed. A renovation demo might turn up steel studs, cast iron pipe, aluminum window frames, and copper wiring all in the same haul. Sorting those streams correctly before you go to the yard changes your payout significantly.
Aluminum is non-ferrous — it doesn't stick to a magnet, it's lightweight, and it commands a much higher price per pound than steel or iron. Even in a down aluminum market, the gap between aluminum and HMS steel is substantial. A pound of aluminum scrap might be worth five to ten times what a pound of steel scrap is worth, depending on the grade and the current market.
So when you're building a load, keep your non-ferrous separate. A few pounds of aluminum accidentally thrown into a steel bin gets priced out at steel rates — you lose the premium entirely. The same logic applies to copper, brass, and stainless. Know what you have, weigh it separately, and sell your scrap metal on GetMyScrap where the process is built around giving sellers clear, transparent pricing by material type.
Aluminum price specifically depends on grade:
- Clean aluminum extrusions — higher value; clean, unpainted, no attachments
- Mixed / painted aluminum — lower than clean extrusions due to mill processing deductions
- Aluminum cans (UBC) — traded actively as a commodity; price fluctuates with LME aluminum
- Cast aluminum — engine blocks, wheels; valued above steel but below clean extrusions
- Aluminum breakage / irony — contaminated aluminum with iron attachments; priced at a discount
Selling Scrap Steel and Iron in Baltimore: What to Know Before You Go
If you're looking for the best scrap metal prices in Baltimore, preparation beats luck every time. Maryland yards are competitive, especially for ferrous — there are multiple buyers in the Baltimore corridor, which means market rates tend to be close to regional benchmarks. But the difference between a good payout and a great payout often comes down to how you present your load.
Baltimore has a strong industrial and construction base, which means yards there see a lot of mixed ferrous. Demolition debris, commercial HVAC equipment, structural steel from industrial retrofits — it moves through Maryland yards regularly. The buyers know what they're looking at. You should too.
A few practical rules before you load the truck:
- Sort your ferrous by grade. Don't mix cast iron with light gauge steel. If you can't separate physically, at least know the rough percentage of each so you can have an honest conversation at the scale.
- Remove obvious non-ferrous attachments. Copper fittings on iron pipe, aluminum brackets on a steel frame — pull those off. You'll get more for the non-ferrous and a cleaner price on the ferrous.
- Know your approximate weight. If you have a trailer scale or access to a public weigh station, weigh your load before you go. It eliminates the guesswork and gives you a reference point when the yard weighs your truck.
- Call ahead on large loads. Baltimore yards sometimes have preferences on what they're buying heavy on a given week based on what they've accumulated. A quick call can save you a trip.
If you want a more streamlined experience — especially for larger loads or recurring material — Baltimore scrap metal services through GetMyScrap connect you to buyers who compete for your material rather than set the price unilaterally.
Why Competition Changes the Price You Actually Get
Here's the thing about scrap: most sellers use one buyer. They call the same yard, take the price offered, and load out. That's the old way. It works, but it doesn't optimize anything. The yard has zero pressure to offer more than baseline because there's no competition in the room.
Platforms like North America's B2B scrap metal auction platform — SMASH — are built specifically to change that dynamic. When vetted buyers compete for your load, price discovery happens in real time. That's how markets are supposed to work. SMASH puts scrap sellers in a position where the buyer is working to win the load, not the other way around.
Whether you're in Baltimore, somewhere else in Maryland, or anywhere across the U.S., more competition means better information. You learn what your material is actually worth in the current market, not what one buyer decided to offer today. That's not hype — it's basic market structure.
SMASH also handles photo documentation, inventory tools, and auto-invoicing, which matters when you're moving multiple loads or managing mixed ferrous and non-ferrous material. Less paperwork friction means faster deals and cleaner records.
How to Position Your Scrap Load for the Best Price in Any Market
Whether you're selling structural steel, cast iron, or a mixed non-ferrous load that includes aluminum, the positioning steps are the same. Documentation, sorting, and market timing all move the needle — and none of them require specialized knowledge, just discipline.
Start with what you have. Photograph your load before it moves. Note approximate weights by category. Separate your non-ferrous from your ferrous. If you have catalytic converters, keep those completely separate — they need VIN or serial tracking and price on their own PGM-driven market, not with your steel. If you want to get a fair price for your scrap today, showing up organized is half the battle.
Timing also matters. Ferrous prices tend to soften in slow construction periods and firm up when mill demand picks up heading into active building seasons. Aluminum pricing tracks LME with a lag. Neither metal holds a static price — the market moves, sometimes weekly. Checking current rates before you sell isn't paranoia, it's just good practice.
Frequently Asked Questions
Q: Is cast iron worth more than steel scrap?
Cast iron is often priced slightly higher per pound than light gauge steel due to its density and specific foundry demand. However, clean HMS (heavy melting steel) can price competitively with or above cast iron depending on market conditions. It varies by yard and by what buyers are actively accumulating that week.
Q: What's the difference between HMS1 and HMS2?
HMS1 (Heavy Melting Steel 1) is heavier gauge steel — typically quarter inch or thicker — free of prohibited metals and excessive rust. HMS2 allows thinner gauge material and generally prices below HMS1. Most yards grade your load on arrival, so knowing which category your material falls into helps you set realistic expectations before you pull up to the scale.
Q: Where can I find the aluminum scrap price today in Baltimore?
Aluminum prices fluctuate with LME movements and local yard demand, so calling yards directly or using a platform that shows real buyer bids is the most accurate approach. GetMyScrap and SMASH both connect sellers with active buyers so you're seeing market price, not a posted number that may be days old. Prices change — always check current rates before you sell.
Q: How do I get the best scrap metal prices in Maryland?
Sort your loads by material type, remove non-ferrous attachments from ferrous scrap, document your load with photos, and bring your material to buyers who are competing for it rather than setting a take-it-or-leave-it price. Multiple buyers bidding on your load is the fastest path to understanding what your scrap is actually worth in today's market.
Q: Can I sell scrap metal online instead of driving to a yard?
Yes. Platforms designed for scrap sellers let you list loads, upload photos, and receive competitive bids without cold-calling yards. This is especially useful for larger loads or specialty material like catalytic converters, where price varies significantly between buyers. Selling scrap metal online saves time and creates the buyer competition that a single yard call never produces.
If you've got steel, iron, aluminum, or a mixed load sitting on your lot, don't guess at the price — find out what the market will actually pay. Request a pickup and get a fair price for your scrap today at getmyscrap.com. The load's already there. Might as well get the right number for it.
Disclaimer: Scrap metal prices fluctuate based on market conditions, grade, and buyer demand. Always verify current rates before selling.
