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.
