Ni-Cu-Ni Coated Powder Metallurgy Magnet for Wind Turbines - N38SH to N52UH Grades

Meta Title: Ni-Cu-Ni Coated Powder Metallurgy Magnet for Wind Power | High Durability
Meta Description: ISO-certified powder-metallurgy neodymium magnets with triple-layer Ni-Cu-Ni coating for wind turbines. 150 °C rating, ±0.05 mm tolerance, custom arcs & blocks, global stock.

  1. 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.

  1. 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.
