Custom High Performance Ceramic Magnets

As a trusted global manufacturing partner and supplier specializing in custom high-performance ferrite (ceramic) magnets, we serve industrial OEMs, electric motor manufacturers, and automation equipment builders. By leveraging optimized strontium ferrite formulations (SrO*6Fe2O3) and precision high-temperature sintering, we deliver magnets with stable magnetic output, exceptional environmental stability, and tight dimensional tolerances.

Global Quality & Compliance: Certified under ISO 9001 and IATF 16949, our operations strictly align with international automotive and industrial quality standards. All products are fully compliant with RoHS and REACH environmental directives, backed by full lot traceability.

High-performance ceramic magnets are permanent magnets manufactured from iron oxide and strontium ferrite. Through advanced powder preparation, wet/dry pressing, sintering, and precision machining, these magnets provide reliable, long-term magnetic retention with inherent resistance to oxidation.

Core Material Advantages
Cost-Effective Scalability: Significantly lower raw material costs compared to rare-earth alternatives (such as NdFeB), making them the optimal choice for high-volume manufacturing.

Superior Corrosion Resistance: Stable metallic oxide composition eliminates the need for protective electroplated coatings, preventing flaking or peeling.

High Thermal Stability: Maintains stable magnetic properties and domain orientation in continuous operating environments up to 250°C.

High Intrinsic Coercivity: Excellent resistance to external demagnetization fields, ensuring dependable performance over time.

Batch-to-Batch Magnetic Consistency: Inconsistent magnetic strength causes calibration failures in motors and sensors. We maintain strict control over raw material particle size and sintering dwell times to ensure predictable magnetic flux density across large production runs, minimizing secondary assembly adjustments.

Uncoated Environmental Durability: Because ferrite magnets are chemically stable oxides, they do not require protective nickel, zinc, or epoxy coatings. This prevents coating delamination in humid or wet conditions, making them ideal for water pumps, fluid flow meters, and outdoor automation.

High-Temperature Domain Stability: Unlike neodymium magnets, which experience severe magnetic degradation at elevated temperatures, our strontium ferrite formulations maintain stable magnetic flux up to 250°C, fitting continuous-duty industrial motors and heating elements.

Rigorous In-House Testing & Traceability: Every production batch undergoes strict testing for remanence (Br), coercivity (Hcb/Hcj), maximum energy product (BHmax), and dimensional accuracy using calibrated hysteresis graphs and 3D projectors. Each shipment is laser-marked or labeled with a unique lot code for complete backward and forward traceability.

We manufacture custom ferrite magnets precisely to your engineering drawings, CAD models, or physical samples.

Available Geometries: Blocks, Discs, Rings, Arcs, Segments, and complex irregular profiles.

Precision Finishing Operations: Advanced grinding and cutting to achieve tight dimensional tolerances (+/-0.05 mm or per specification).

Documentation Support: Material Test Reports (MTR), Magnetic Flux Reports, and Dimensional Inspection Sheets supplied with every shipment.

Electric Motors & Actuators: Widely integrated into Permanent Magnet Direct Current (PMDC) motors and brushless DC applications requiring steady magnetic fields and temperature resistance.

Sensors & Reed Switches: Delivers repeatable, precise magnetic switching points for industrial automation equipment and security systems.

Magnetic Separation Systems: Utilized in recycling, agricultural, and mining setups due to high coercivity and resistance to environmental degradation.

Acoustic Transducers: Built into loudspeaker magnetic circuits to provide cost-effective, high-volume sound reproduction.

Requirement Submission: Send your CAD drawings, target dimensions, material grade, and estimated annual usage (EAU) to our engineering team.

Engineering Feasibility Review: Our technical experts evaluate tooling design, pressing direction, and magnetic orientation requirements, returning a formal DFM (Design for Manufacturability) report within 24 hours.

Prototyping & Sampling: Rapid sample production for physical assembly, prototyping, and functional verification (Standard sampling lead time: 2 to 3 weeks).

Volume Production & Global Logistics: Mass manufacturing backed by in-process quality control, export-compliant protective packaging, and standard production scheduling (Mass production lead time: 3 to 4 weeks).
