How to Choose the Right Magnet Material
| Material | Strength | Max Working Temp | Corrosion | Relative Cost | Best For |
|---|---|---|---|---|---|
| Sintered NdFeB | Highest | 80–200 °C | Needs coating | High | Compact high-force designs |
| SmCo | High | 250–350 °C | Excellent | Very high | Aerospace, high temperature |
| AlNiCo | Medium | up to 550 °C | Good | Medium | Stable flux instruments |
| Ferrite | Low | 250 °C | Excellent | Lowest | Cost & outdoor use |
| Rubber / Flexible | Very low | 70–80 °C | Excellent | Low | Thin flexible surfaces |
| Bonded NdFeB | Medium | 100–150 °C | Good | Medium | Complex shaped multi-pole parts |
