Best for projects requiring custom geometry plus reliable field behavior at elevated temperature.
| Product Family | Primary Buyer Focus | Key Metric | Why It Matters |
|---|---|---|---|
| SmCo5 Magnets (1:5) | Best for engineering teams that need compact high-reliability magnets with predictable thermal behavior. | Recommended operating range: -55°C to +250°C | Prevents under-specification when the magnet works near thermal limits. |
| Sm2Co17 Magnets (2:17) | Best for teams prioritizing thermal headroom, magnetic retention, and long-lifecycle reliability. | Recommended operating range: -55°C to +350°C | Protects critical assemblies from magnetic degradation under high heat. |
| SmCo Ring Magnets | Best for teams that need strict geometric consistency with defined magnetic orientation in ring form factors. | Concentricity capability: Defined per geometry and tolerance stack | Directly impacts field symmetry and system-level repeatability. |
| SmCo Disc & Block Magnets | Best for projects requiring custom geometry plus reliable field behavior at elevated temperature. | Dimensional tolerance readiness: Reviewed per geometry and process route | Determines assembly fit and downstream scrap risk during pilot builds. |
