From Raw Material to Final Product: Inside the Neodymium Magnet Supply Chain

What is a Neodymium Magnet?

These magnets are super strong! They pull metal really, really hard. People put them in all sorts of stuff. Stuff that can’t be made without something as strong as a Neodymium Magnet. We call them NdFeB magnets because of the things that make them unique. This is short for neodymium, iron, and boron. These are elements. These magnets are small but mighty!

• They help make electric cars go.
• They make windmills turn to make power.
• Doctors use them in MRI machines that scan the body.
• You can find them in your headphones and speakers.
• They are even in games and toys! [^29]

We make these strong magnets for you! We are good at it, and want to show you!

We are your go-to NdFeB Magnets Factory!

Finding the Stuff to Make Magnets! (Sourcing Rare Earth Materials)

First, people dig up rocks. These rocks are rare earth elements (REEs). You can find these elements in the crust of our planet. We call the rocks minerals. The minerals in the rock that we care about are the ones we call Bastnäsite and Monazite. These have the neodymium.

• Most of these rocks come from China.
• Some come from the USA and Australia, too.
• It is kind of like a treasure hunt to find them!

But, digging can hurt the Earth. Mines can cause pollution. The mining process can affect water usage in mining.

We get our rocks from good places. We make sure it is safe, and do not pull from any conflict mineral policies

Making the Magnet Mix! (Refining and Alloy Production)

It is like cooking! But with hot metal, not food.

1. We get the neodymium out of the rocks with Rare Earth Element Extraction. We also preform Rare earth purification and impurity removal. This is not easy!
2. We mix it with iron and boron. This forms the NdFeB structure. When the three are mixed together at the right time, and the right amounts it becomes a powerful alloy (NdFeB).

3. We use a special way to mix it:

   • Solvent extraction: Like making juice.
   • Strip casting: Making thin metal sheets.
   • Hydrogen decrepitation: Using gas to break it up.
   • After we get all the rare earth elements we want, we dispose of the tailings management safely.

We use different kinds of ways to do this based on what you, our customer needs:

• Hydrometallurgical processing: This is a great way to get good ore concentration.
• Electrowinning techniques: Makes it very pure.
• Smelting and calcination

We are very good at this. So, we can mix it right. Our magnets are the best!

These ways of mining, and mixing are all Metallurgical techniques.

We are experts at making the best Magnet Grade for your needs

Making the Magnet Shapes! (Magnet Manufacturing)

Now, we make the magnets! It is like making cookies.

1. Powder metallurgy: We make the mix into tiny bits, a rare earth powder. Like flour.
2. Pressing and compaction: We squish the bits into a shape. Like making cookies, but we press them into blocks, circles, and squares.
3. Sintering process: We make it hot to stick together. It is like baking! Vacuum sintering is used when we need to be extra careful.
4. Magnet shaping (blocks, discs, rings): We cut it into the shape you want.
5. Cryogenic milling: Sometimes, after we start making the magnets, we will use this process to mill it down better!
6. Magnet magnetization: Add the magic! Make it pull metal.
7. We put a shiny shield. This is the coat. The magnet coating (nickel, zinc) that keeps away rust. Like jackets for magnets!
8. Magnet corrosion protection: We use high-tec tools to check if the coating is perfect.
9. Magnet performance testing: We make sure it’s strong enough.

And the best part, we can also make the magnets gold magnetic!

We do cool ways, like:

• Magnetic separation technology
• Magnet assembly processes

We can make any shape! Big, small, round, square. You pick!

We have many Magnet Coating options. Just ask!

Where Do Magnets Go? (Applications Across Industries)

These magnets are everywhere:

• Cars: Electric cars use lots of them!
• Windmills: To make clean power.
• Robots: To move and do things.
• Phones: Speakers and motors.
• Planes: In engines and other parts.
• Hard Drives: In computers.
• MRI Machines: Help the doctor look at people.[^37]
• Home: You can find them in your kitchen in your household appliances!

More places you can find them:

• Renewable energy systems: They are good for the Planet.
• Automotive electrification: Many cars are starting to use this!
• Aerospace applications: In all the newest flight stuff!

It is crazy how many magnets are used! Here are just a few:

• Robotics and actuators: To be quick.
• Permanent magnet properties: to be strong!
• Hard disk drives: To go in hard drives and computers!

One time, a company used our magnets. They made their car motors smaller!

Problems in Getting Magnets (Challenges in the NdFeB Supply Chain)

Sometimes, it is hard to get these magnets.

• The world needs to come together to get rocks. It can be tricky because countries do not work together.
• There could be conflict, and it’s hard to get all the resources you need (mineral deposit exploration might be slow).
• We want to be good to the Earth.

Here are some ways we get around this:

• Mining permits and regulations
• Making sure we are ok: ISO 9001 certification[^27]
• Environmental compliance
• Raw material traceability: We know where all the minerals come from.
• Critical mineral strategies: We have a good plan!

Here are some things we need to think of in the process:

• Ore refinement
• Supply chain logistics
• Making sure we are ok: ISO 9001 certification
• Environmental compliance
• Raw material traceability
• Critical mineral strategies

We store lots of stuff. So we always have enough for you.

Keeping it Green! (Sustainability & Recycling)

It is good to use things again.

• We can take old magnets and make new ones!
• This helps the Earth.
• It helps the planet, and also provides us more rare earth element.s
• There are now special magnet recycling technologies that take apart old electronics that still have useful materials inside.

We do this! It is good for all of us. It is part of being good to the Earth. We make magnets, but we also care about the Earth. The Circular economy initiatives help make this work.

There are also rules we need to follow when making these magnets.

• Export/import regulations
• Global rare earth trade.
• Trade policies (e.g., tariffs)
• Rare earth stockpiling: We always save some extra.
• Conflict mineral policies: This helps us stop bad things from happening.

We are green. We want a clean future, so offer many Customized Neodymium Magnets from recycled content
