ISO9001 Certified Sintered Neodymium Magnet for High-Temperature 80-220°C Applications

Neodymium–Iron–Boron (NdFeB) for 80 °C – 220 °C High-Temperature Applications
Meta Title: ISO 9001 High-Temp NdFeB Magnet 80-220 °C | Sintered Neodymium Iron Boron
Meta Description: ISO 9001 certified sintered NdFeB magnets rated 80–220 °C. N35SH–N54EH grades, ±0.05 mm tolerance, Ni-Cu-Ni or epoxy coating. Perfect for motors, sensors, actuators. Global stock & 7-day custom.

  1. 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.

  1. 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.
