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.
