AlNiCo Permanent Magnets

Cast AlNiCo magnets can operate continuously up to 550 °C, making them the preferred choice for high-temperature instruments and aerospace applications.

Cast AlNiCo allows complex shapes and higher magnetic output (up to about 13.5 MGOe), while sintered AlNiCo offers tighter dimensional tolerance and better mechanical consistency for smaller precision parts.

Yes, sample orders are welcome. Send your drawing or specification together with the intended application so our engineers can recommend the correct grade, magnetization direction and coating before we prepare samples.

Yes. We machine, grind and inspect to customer drawing tolerances. For sintered NdFeB the standard machining tolerance is ±0.05 mm and can be tightened to ±0.02 mm with diamond grinding where the geometry allows.

Nickel (Ni-Cu-Ni) for general indoor use, zinc for cost-sensitive applications, and epoxy or Parylene for environments with humidity, salt or organic solvents. Our QC team can help select the best coating for your operating environment.
