SmCo (Samarium Cobalt) Magnets

SmCo keeps high magnetic output at operating temperatures of 250–350 °C where NdFeB demagnetizes, has excellent corrosion resistance without coating, and maintains stable magnetic performance over extreme temperature cycling.

Sm2Co17 offers higher energy product and better temperature coefficient, while Sm1Co5 offers very high coercivity and even better thermal stability. The choice depends on your operating temperature and output requirements.

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.
