What Do Neodymium Magnets Stick To

What Do Neodymium Magnets Stick To?

Have you ever picked up a small, silver magnet and been shocked by how strong it is?

That’s a neodymium magnet. These things are powerful.

But most people don’t actually understand what do neodymium magnets stick to – and what they don’t.

So today, as a professional custom neodymium magnets manufacturer, I’m going to break it all down for you.

What Do Neodymium Magnets Stick To

What Do Neodymium Magnets Stick To?

Neodymium magnets stick exclusively to ferromagnetic metals – materials that can be magnetized and are strongly attracted to magnets (contain elements like iron, nickel, or cobalt).

1. Iron (And Anything That Contains It)

Iron

Iron is the most common ferromagnetic material on the planet.

And because neodymium magnets are so strong, they’ll stick to:

  • Pure iron
  • Cast iron
  • Wrought iron

Most metals you encounter day-to-day aren’t pure iron. They’re alloys.

And that’s where neodymium magnets really shine.

2. Steel (The Heavy Hitter)

Steel

Steel is mostly iron.

Which means neodymium magnets LOVE steel.

In fact, steel is one of the strongest materials for them to stick to.

This includes:

  • Mild steel (used in cars, construction, tools)
  • Carbon steel
  • Tool steel

Pro Tip: If you’re looking for a surface to test your neodymium magnet, grab something made of plain steel. I personally use a steel tool chest in my workshop – it’s perfect for holding all kinds of magnetic accessories.

3. Nickel (Pure Form Only)

Nickel

Pure nickel is ferromagnetic.

But most “nickel” things you see (like nickel coins) aren’t pure nickel. They’re alloys mixed with non-magnetic metals like copper.

So will a neodymium magnet stick to a nickel coin?

Probably not.

But it will stick to pure elemental nickel and certain nickel-heavy alloys.

4. Cobalt

Cobalt

Cobalt is another ferromagnetic metal.

It’s less common in everyday objects, but neodymium magnets will absolutely stick to pure cobalt and some cobalt alloys.

5. Other Rare Earth Magnets

Other Rare Earth Magnets

This one surprises a lot of people.

Neodymium magnets will vigorously stick to other rare earth magnets – including other neodymium magnets and samarium-cobalt magnets.

Just be careful.

I’ve had two Magneti N52 snap together from three inches away and chip the edge of both of them.

Not fun.

The Stainless Steel Confusion (Most People Get This Wrong)

Not all stainless steel is magnetic.

I know, it sounds strange.

But here’s the breakdown:

Ferritic Stainless Steel (Magnetic)

Ferritic Stainless Steel

Grades like 409, 430, 434, and 439 contain more iron and lack something called “austenite.”

Result?

Your neodymium magnet will stick to them just fine.

Austenitic Stainless Steel (NOT Magnetic)

Austenitic Stainless Steel

This is where people get frustrated.

Grades like 304 and 316 (the stuff your kitchen appliances are probably made of) contain high levels of nickel and have a different crystal structure.

Neodymium magnets will NOT stick to austenitic stainless steel.

So if you’ve ever tried to stick a magnet to your fancy refrigerator and watched it fall…

Now you know why.

What Neodymium Magnets DO NOT Stick To

Here’s a list of materials where neodymium magnets will not work:

Common Non-Ferrous Metals

Common Non-Ferrous Metals

  • Aluminum (this one tricks people – it looks like steel but isn’t magnetic)
  • Copper
  • Brass
  • Oro
  • Silver
  • Lead
  • Tin
  • Platinum
Everyday Non-Metal Objects

Everyday Non-Metal Objects

  • Glass
  • Wood
  • Plastic
  • Rubber
  • Ceramic
  • Paper
  • Cloth

The Bottom Line?

If it doesn’t contain iron, nickel, or cobalt in significant amounts…

Your neodymium magnet won’t stick.

A Real-World Example (From My Own Experience)

A few years ago, I wanted to hang a heavy whiteboard in my office.

I didn’t want to drill holes in the wall.

So I grabbed a few neodymium magnets and tried to stick the whiteboard directly to the wall.

It fell. Obviously.

The wall was drywall – not magnetic at all.

But here’s the trick:

I found the steel screws behind the drywall (the ones holding the studs together).

And the magnets stuck to those screws like glue.

That’s actually a pro-level hack:

You can use neodymium magnets to find metal studs behind walls by letting them stick to the steel screws embedded in the wood or drywall.

Works like a charm.

What About “Paramagnetic” Metals?

You might hear this term thrown around.

Paramagnetic metals (like aluminum, copper, and gold) have a very weak attraction to magnets.

But here’s the truth:

You’ll barely notice it.

In fact, for practical purposes, you can consider them non-magnetic.

The attraction is so weak that gravity will overcome it instantly.

So no, your neodymium magnet won’t pick up a copper penny or an aluminum soda can.

Quick Reference Table

MaterialWill a Neodymium Magnet Stick?
Iron✅ YES
Steel (most types)✅ YES
Ferritic Stainless Steel✅ YES
Austenitic Stainless Steel (304/316)❌ NO
Nickel (pure)✅ YES
Cobalt✅ YES
Aluminum❌ NO
Copper❌ NO
Brass❌ NO
Wood/Plastic/Glass❌ NO

Pro Tips For Using Neodymium Magnets

Based on years of messing around with these things, here’s what I’ve learned:

1. Check your stainless steel first – If you’re not sure if something is magnetic, test it with a small magnet before assuming it’ll work.

2. Use a barrier – Put a piece of tape or paper between magnets when sliding them. It prevents them from snapping together too hard.

3. Store them safely – Keep neodymium magnets in a box with foam separators. Otherwise, they’ll find each other and become impossible to separate.

4. Watch your electronics – These magnets can damage credit cards, hard drives, and pacemakers. Don’t put them near anything sensitive.

Final Thoughts

So let’s circle back to the main question:

What do neodymium magnets stick to?

They stick to ferromagnetic metals – primarily iron, steel, nickel, and cobalt.

They do NOT stick to aluminum, copper, brass, austenitic stainless steel, or any non-metal materials.

And because they’re incredibly strong, they’re perfect for heavy-duty applications… as long as you use them on the right surface.
