If you’ve ever brought scrap metal to a recycling yard or wondered how to sort through the different types of metal in your garage, you’ve probably come across the terms ferrous and non ferrous. But what do they actually mean? And why does it matter when it comes to scrap metal recycling?
At Sutter Metals, we help people across Tacoma and the South Sound recycle metal every day. Knowing the difference between ferrous vs non ferrous metals makes the process easier, more rewarding, and better for the environment. Let’s dig into what sets these metals apart, examples of each, and how to sort scrap metal like a pro.

Ferrous vs Non Ferrous Metals: The Basics
The biggest difference between ferrous and non ferrous metals is simple: Ferrous metals contain iron. Non ferrous metals do not.
That’s it! But this one difference leads to very distinct properties, uses, and recycling considerations. Let’s dive deeper.
Ferrous Metals
Ferrous metals are strong, magnetic, and commonly used in construction and manufacturing. If you think of heavy-duty items like steel beams, car parts, or cast iron pans, you’re thinking of ferrous metals.
Common Examples of Ferrous Metals
- Steel (used in buildings, tools, cars, appliances)
- Cast iron (skillets, pipes, radiators, bathtubs)
- Wrought iron (decorative fencing, gates)
Because ferrous metals are magnetic, they’re usually easier to identify and sort. A simple magnet test can quickly tell you if you’re dealing with a ferrous metal—if the magnet sticks, it’s ferrous.
Non-Ferrous Metals
Non-ferrous metals, on the other hand, are lighter, corrosion-resistant, and often more valuable as scrap. Since they don’t contain iron, they aren’t magnetic.
Common Examples of Non Ferrous Metals
- Aluminum (cans, siding, car parts, foil)
- Copper (wiring, plumbing pipes, roofing)
- Brass (plumbing fixtures, musical instruments)
- Lead (batteries, roofing materials)
- Zinc (coatings, alloys like brass)
These metals are prized for their unique properties. Copper is an excellent conductor of electricity, which is why it’s used in wiring. Aluminum is lightweight and resistant to rust, making it a go-to in transportation and packaging.
Why the Difference Matters in Recycling
So why should you care about ferrous vs non ferrous metals when it comes to recycling? Because it affects both the process and the value of your scrap.
Ferrous metals are recycled in large quantities. They’re incredibly common, and while they may not fetch the highest price, they’re essential to keep out of landfills. Recycling steel, for instance, saves up to 75% of the energy it would take to make new steel from raw materials (U.S. Environmental Protection Agency).
Non ferrous metals tend to be worth more per pound. Copper and aluminum, for example, are highly sought after in non ferrous metal recycling. Their properties don’t degrade when recycled, which means they can be reused indefinitely without losing quality.
At Sutter Metals, we accept both ferrous and non ferrous metals, making it easy for you to recycle responsibly—no matter what kind of scrap you have.
How to Sort Scrap Metal
Sorting scrap metal doesn’t have to be complicated. With just a magnet and a little know-how, you can make the process much easier.
- Grab a magnet. Place it against the metal in question.
- If it sticks strongly → ferrous metal.
- If it doesn’t stick → non ferrous metal.
- Separate into two piles. One for ferrous metals (like steel and iron), and one for non ferrous metals (like copper, brass, aluminum).
- Remove non-metal attachments. Items like wires, screws, or plastic coatings can usually be stripped or separated for easier processing.
Sorting your metals ahead of time can save you time at the recycling yard and sometimes even help you get a better return. Plus, it keeps the recycling process efficient and environmentally friendly.
Everyday Examples: What’s in Your Home or Garage?
Understanding types of metal isn’t just for contractors or scrap yards—you probably have a mix of ferrous and non ferrous metals in your home right now.
Old appliances, pipes, patio furniture, tools, and kitchenware often contain ferrous metals. Alternatively, soda cans, extension cords, plumbing fixtures, and bicycle frames are just a few of the common places you might find non-ferrous metals at home.
Once you start recognizing them, it’s easier to set items aside for scrap metal recycling instead of tossing them in the trash.
Sutter Metals: Tacoma Recycling Made Simple
Here in Tacoma, we know how important it is to keep our community clean and sustainable. Scrap metal recycling plays a big role in reducing waste and conserving resources. Recycling just one ton of steel saves about 2,800 pounds of iron ore, 1,600 pounds of coal, and 600 pounds of limestone.
By separating ferrous vs non ferrous metals, you’re helping make the recycling process smoother and more impactful. At Sutter Metals, we’re here to make sure your efforts go as far as possible.
