FAQ
Ferrite Demagnetization Curves — FAQ
Can ferrite withstand continuous demagnetizing fields?
Ferrite has high coercivity and is fairly stable, but sustained strong opposing fields can still cause irreversible loss. Verify the working point with the B-H curve for your design.
Is curve data available for FEM simulation?
Yes, we provide tabulated B-H data compatible with FEM software on request.
Do you provide free samples for testing?
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.
Can the factory produce to my drawing with special tolerances?
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.
