Meta Title: Grade 35H–48H Neodymium Iron Boron Magnets | Industrial Strength | Fast Quote
Meta Description: High-performance Grade 35H–48H neodymium iron magnets deliver 11.7–14.3 kG remanence and 120 °C operation. Perfect for motors, sensors, and magnetic assemblies. ISO-certified, ±0.05 mm tolerance, global delivery.

Product Overview
When your application demands maximum holding force and thermal stability up to 120 °C, choose Grade 35H–48H neodymium iron boron (NdFeB) magnets. Sintered for industrial strength, these magnets provide 11.7–14.3 kG remanence and ≥ 17 kOe coercivity—ideal for servo motors, linear actuators, magnetic separators, and sensor assemblies.

Key Benefits

• Grade 35H–48H Range – balanced energy vs. temperature for 120 °C continuous use.
• Industrial Strength – >50× stronger than ceramic magnets at equal size.
• ±0.05 mm Precision – press-fit into rotors, no secondary machining.
• Multi-Coat Protection – Ni-Cu-Ni, epoxy, or parylene ≥ 500 h salt-spray.
• ISO-Certified Plant – ISO 9001 & ISO 14001, RoHS & REACH compliant.
• 7-Day Prototypes – laser-cut tooling, fast sintering cycle.
