- 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.
