Ndfeb Materials

Core Features
Outstanding Magnetic Performance
Available in grades from N35 to N52, with maximum energy product ranging from 280 kJ/m (35 MGOe) to 400 kJ/m (50 MGOe). High remanence (1.17-1.45 T) and coercivity (876 kA/m) ensure strong and stable magnetic force.

Durable & Corrosion-Resistant
Surface treated with nickel-copper-nickel (Ni-Cu-Ni) plating as standard, with optional gold, silver, or epoxy coating. Effectively resists corrosion and wear, extending service life in harsh environments.

Precision Dimensions
Customizable block sizes (length: 2-250mm, width: 1.5-150mm, thickness: 0.5-50mm) with tight dimensional tolerance ±0.03mm to ±0.15mm depending on size), ensuring perfect fit for assembly.

Wide Operating Temperature Range
Standard grade (N series) operates at -40 to 80; high-temperature grades (M/H/SH/UH/EH) are available for environments up to 200, meeting diverse application requirements.
