NdFeB Magnets: High-Performance Magnetic Solutions for Small Appliances
NdFeB Magnets: Good Magnets for Small Things!
Table of Contents
What are NdFeB Magnets?
NdFeB magnets are rare earth magnets. “Rare earth” means they are made from special stuff. This stuff is not easy to find! These magnets are also called neodymium magnets. They are the strongest magnets you can buy!
: Rare earth magnets are strong magnets. : Neodymium magnets are strongest.
Why are They Good for Small Things?
- Small size, big power: NdFeB magnets are small but very strong. This is good for small appliances. You don’t need a big magnet.
- They last long: These magnets stay strong for a long time.
- They work in hot and cold: changes in temperature can make magnets get weaker, but NdFeB magnets are more temperature Stable.
- No rust!: If magnets get wet, they can rust. NdFeB magnets have a special coating. The coating stops rust. We offer Nickel, zinc, and gold coatings.
: Small but strong. : Stays Strong. : coating to stop rust.
How We Make NdFeB Magnets
Making these magnets is like making a cake! But it is much harder.
- Mix the stuff: We mix neodymium, iron, and boron. These are like the flour, eggs, and sugar for our magnet “cake.”
- Press it hard: We put the mix in a special mold. Then we press it very, very hard.
- Bake it: We put the mold in a hot oven. This is called sintering.
- Cool it: We let it cool down slowly.
- Cut it: We cut the big magnet into smaller shapes. We can make any shape you need!
- Coat it: We put a special coating on the magnet, like a jacket, so its a corrosion-resistant coating. This keeps it safe from water and air.
- Make it magnetic: We use a big machine to make it a magnet. This is called magnetization.
: Sintering is like baking.
We are a Neodymium Magnets Factory. We do all these steps! This means we can make the best magnets for you.
What Can You Make with NdFeB Magnets?
You can put NdFeB magnets in lots of small appliances!
| Appliance | What the Magnet Does |
|---|---|
| Blender | Makes the blades spin very fast |
| Vacuum cleaner | Helps the motor suck up dirt |
| Fan | Spins the blades to blow air |
| Hair dryer | Makes the motor spin to blow hot air |
| Electric toothbrush | Makes the brush head move back and forth |
| Refrigerator | Keeps the door closed tight |
| Cabinet door | Keeps the door shut |
| Smart home device | Talks to other devices to change settings. |
Case Study: Blender
A company made a new blender. They used a big, old magnet. The blender was big and heavy.
Then, they asked us for help! We gave them a small NdFeB magnet. It was N42SH grade. This means it can work when it’s hot.
The new blender was:
- Smaller
- Lighter
- Used less power
- The magnet helped it work a lot better.
: N42SH grade is good for hot things.
This is like the case study!
Miniaturized brushless DC motor + fan reduced oven size by 35% while maintaining airflow efficiency. aspina-group.com
We can do the same for you! We are so good, we can even make Customized NdFeB Magnets!
How to Pick the Right NdFeB Magnet
It’s like picking the right shoes! You need the right size and type.
1. Size and Shape
- How big is your appliance?
- What shape do you need? We can make any shape!
- Blocks
- Discs
- Rings
- Custom shapes
2. Grade
The grade tells you how strong the magnet is.
- N35 is strong.
- N52 is very, very strong. It has a high energy density!
- For hot things, use N42SH or N38SH.
- Grain boundary diffusion of the raw materials makes it more resistant to heat.
: Grade = strength. : N52 = super strong.
3. Temperature
- How hot will the magnet get?
- NdFeB magnets can work up to 150°C!
- If it gets too hot, it can lose its power. This is called demagnetization.
: 150°C is very hot!
4. Coating
The coating protects the magnet.
- Nickel is good.
- Epoxy is even better.
- Gold is the best, but it costs more, but it’s a great corrosion-resistant coating.
5. Magnetic Field Strength
We check magnetic field strength so you always get the best.
6. Intrinsic Coercivity
We make sure that the intrinsic coercivity is just right.
7. Magnetic Flux Density
We can measure the magnetic flux density, guaranteed.
We can help you pick the right magnet. Just ask!
