ISO 14001 Certified High-Temperature Sintered Neodymium Magnet for Industrial Use

High-Temperature Sintered Neodymium Magnet – ISO 14001 Certified for Industrial Applications
Meta Title: ISO 14001 High-Temp Sintered NdFeB Magnets | 150–230 °C Grade | Industrial Use
Meta Description: Certified ISO 14001 high-temperature sintered neodymium magnets (N35AH–N54UH) rated 150–230 °C. Precise tolerances, anti-corrosion coatings, and fast global delivery for motors, sensors, and pumps.

  1. Product Overview
    Boost efficiency in demanding environments with our high-temperature sintered neodymium magnets. Manufactured under ISO 14001 environmental standards, they retain ≥90 % flux at 150 °C to 230 °C, outperforming standard N-series grades. Ideal for servo motors, turbochargers, magnetic couplings, and down-hole sensors.
