1、 High precision: The required precision is obtained after the shape-forming, without further process. 2、Excellent magnetic properties: The energy product is 3 times as large as anisotropic ferrite. The intrinsic coercive force is high. During the large-scale production, the magnetic properties are stable and the conformity is good. 3、Stable working temperature: The working temperature is high up to 150℃. 4、Good corrosion-resistance and nice surface: The product is coated with epoxy resin parylene-coating and the anti-corrosion is very good. The surface is smooth, clean and nice-looking. No bubble, no crack, no strip-off, and no chip.
