Product Overview
Our wind-power-grade powder-metallurgy magnets combine high-energy magnetic performance with extreme durability. Each magnet is compact-pressed and sintered, then finished with a triple-layer Ni-Cu-Ni coating to withstand salt spray, humidity, and thermal cycling in offshore and onshore wind turbines.
Key Benefits
- Wind-Turbine Optimized - N38SH-N52UH grades deliver 11.7-14.8 kG at 150 °C.
- Ni-Cu-Ni Triple Coating - 1,000 h salt-spray (ASTM B117) for offshore life.
- Powder Metallurgy Precision - ±0.05 mm tolerance, minimal eddy-current losses.
- Custom Arc & Block Shapes - fit stator & rotor slots perfectly.
- Eco & Quality Certified - ISO 9001, ISO 14001, IATF 16949, RoHS, REACH.
- 7-Day Prototypes - 3-D printed tooling, global express delivery.
