Bonded NdFeB Magnets

Rare-earth bonded NdFeB magnet components for compact rotors and sensing parts that need stronger output than ferrite.

Target Buyer:Best for buyers who need stronger magnetic performance but still require molded shape control and chip-free handling.

Capability Highlights

Higher magnetic output than bonded ferrite in compact envelopes
Moldable geometry for rings, sleeves, hubs, and custom rotor shapes
Suitable for precision sensor, motor, and actuator programs

Typical Applications

Compact motor rotors
EV sensor modules
Encoder rings
High-output molded magnets

Engineering Focus

Magnetic output versus resin loading and mechanical strength
Corrosion, temperature, and coating/encapsulation assumptions
Tooling wear and powder loading impact on production repeatability

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Magnetic output target	Flux density or sensor curve defined by buyer test setup	Bonded NdFeB is selected when ferrite cannot meet signal or torque density in the available package.

RFQ Checklist

2D/3D drawing, material target, magnetic pattern, and sensing datum
Operating temperature, vibration, media exposure, and lifetime requirement
Sample quantity, tooling target, annual forecast, destination, and PPAP needs

Risk Controls

Brittle sintered magnet carried into a vibration-critical assembly: Review bonded magnet material and molded geometry when chipping, cracking, or adhesive failure can affect functional safety.
Magnetic pattern accepted without measurable criteria: Define flux density, pole count, angle error, sensing radius, concentricity, and inspection method before sample tooling.

Buyer FAQ

Is bonded NdFeB as strong as sintered NdFeB?

No. Bonded NdFeB normally has lower energy density than sintered NdFeB, but it enables molded shape complexity, crack resistance, and multi-pole production advantages.
