Ferrite Block Magnet 50x25x10mm

Ferrite Block Magnet 50×25×10mm is a rectangular ceramic permanent magnet manufactured with a 50 mm length, 25 mm width, and 10 mm thickness for magnetic holding, separation, and industrial magnetic field applications.
Produced from strontium ferrite material through pressing and high-temperature sintering processes to provide stable magnetic properties and corrosion resistance without additional surface coating.
The block structure supports axial magnetization through the 10 mm thickness direction, generating magnetic flux between the two large flat surfaces.
Commonly used in magnetic separators, magnetic holding systems, motor assemblies, sensors, speakers, and OEM industrial magnetic components requiring stable magnetic field distribution and rectangular installation structures.

Material & Magnetic Properties

Material Type: Manufactured from high-quality ceramic ferrite, these magnets offer strong magnetic performance while remaining affordable.
Density: With a density range of 4.8 - 5.0 g/cm³, ferrite magnets are lightweight yet robust, ideal for various robotic applications.
Coercivity: These magnets exhibit a coercivity range of 1500 - 3000 Oe, which ensures excellent resistance to external demagnetizing fields, crucial for robotics where stability is essential.
Remanence (Br): A remanence range of 2000 - 4500 Gauss ensures strong magnetic flux retention, enhancing the motor's efficiency and performance.

Quality Control System

Dimensional Inspection

Each Ferrite Block Magnet 50×25×10mm is measured for length, width, and thickness to ensure accurate fit in motor assemblies, magnetic fixtures, and industrial equipment structures. This controls assembly alignment and reduces installation deviation during mass production.

Magnetic Testing

Magnetic flux and surface field strength are tested during batch production to maintain consistent magnetic performance between individual magnets. This ensures stable magnetic field distribution in motors, magnetic separators, and other industrial applications.

Surface & Batch Verification

Surface inspection is carried out to detect cracks, edge chipping, and sintering defects that may affect structural integrity. Final batch sampling is performed before shipment to confirm dimensional stability and production consistency.

FAQ
