Sintered vs bonded NdFeB: manufacturing trade-offs
Compare sintered and bonded NdFeB for strength, temperature, and geometry.
Last updated on 2026/01/26
Overview
Sintered and bonded NdFeB serve different design needs. Understanding the trade-offs helps reduce cost and improve manufacturability.
Sintered NdFeB
- Higher magnetic strength.
- Better for high-performance applications.
- Typically more brittle and limited in complex shapes.
Bonded NdFeB
- Lower magnetic strength than sintered.
- Allows more complex shapes and tighter dimensional control.
- Often useful for high-volume, complex geometry parts.
Procurement considerations
- Performance vs geometry trade-offs.
- Tolerance requirements and finishing steps.
- Lead time implications based on tooling and processing.
RFQ guidance
- Specify performance targets and key dimensions.
- Indicate whether complex geometry is required.
- Confirm acceptable tolerances and coating needs.
