Demagnetization curves for AlNiCo grades show its characteristic behaviour — high remanence, low coercivity and excellent linear stability over temperature.
Curve data supports design and working-point verification.

FAQ
AlNiCo Demagnetization Curves — FAQ
Why does AlNiCo demagnetization curve matter for instrument design?
Because AlNiCo has low coercivity, verifying the working point on the B-H curve prevents irreversible loss when the magnet faces opposing fields.
Can AlNiCo be stabilized before shipment?
Yes, we offer partial demagnetization stabilization so the magnet reaches its final operating point in application.
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.
