Product Overview
Need reliable magnetic performance where temperatures soar? Our ISO 9001 certified sintered neodymium-iron-boron magnets are engineered for continuous operation from 80°C up to 220°C. Choose from N35SH to N54EH grades with automotive-grade dimensional accuracy and multi-layer anti-corrosion coatings—ideal for servo motors, turbo actuators, down-hole sensors, and magnetic couplings.
Key Advantages
- 80 - 220°C Range - SH, UH, EH grades prevent demagnetization at high heat.
- ISO 9001 Certified - full process traceability and consistent quality.
- Energy Levels 33-53 MGOe - maximum torque density in compact spaces.
- ±0.05 mm Precision - press-fit into rotors without secondary machining.
- Triple-Layer Coatings - Ni-Cu-Ni, epoxy, Zn, parylene ≥ 500 h salt-spray.
- 7-Day Custom - prototypes or volume orders, global shipping.
