A cool guide of neodymium magnet grades
I work with Neodymium (NdFeB) magnets every day, and if there’s one thing I’ve noticed, it’s that picking the wrong grade is the #1 cause of project failure. Whether it's losing strength in heat or just not being strong enough, the 'N' numbers can be confusing. Here’s a quick, no-nonsense breakdown to help you pick the right one.
**1. The "N": Stands for Neodymium Iron Boron.**
**2. The Number (e.g., 35, 42, 52): This is the Maximum Energy Product.**
* Higher number = Stronger magnetic pull.
* N52 is currently the strongest grade.
**3. The Trailing Letters (The Temp Grade):**
This is where most people fail. The letter tells you the Max Working Temperature:
|Grade|Max Working Temperature|
|:-|:-|
||
|N|≤80℃|
|M|≤100℃|
|H|≤120℃|
|SH|≤150℃|
|UH|≤180℃|
|EH|≤200℃|
|AH|≤220℃|
**Pro Tip:** A thicker magnet is actually more resistant to demagnetization than a thin one of the same grade!
Happy to answer any technical questions if you're stuck on choosing the right magnet for your DIY project or design!
