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.

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.

High-Temperature Applications

• Servo & Stepper Motors – stable flux at 150 °C windings.
• Turbo Actuators & EGR Valves – survive under-hood 180 °C spikes.
• Oil & Gas Sensors – 220 °C down-hole reliability.
• Magnetic Couplings & Pumps – zero leakage, high torque transfer.
• Wind-Turbine Pitch Controls – long-term demagnetization resistance.
