Product Overview
This N52 neodymium magnet is a high-energy permanent magnet produced from premium NdFeB (neodymium iron boron) material, selected for applications requiring compact size and strong magnetic output. Compared with lower-grade magnetic materials, N52 offers greater magnetic flux density in the same volume, enabling engineers to design smaller, lighter magnetic assemblies without reducing performance.
Rather than presenting generic strength claims, this product emphasizes stable magnetic behavior, precision manufacturing, and ease of integration into assemblies such as motors, sensors, fixtures, and automation modules.

N52 magnets achieve a high maximum energy product (BHmax) while maintaining coercivity and remanence suitable for a wide range of industrial tasks.
Key Performance Characteristics
Compact Field Strength
The N52 grade provides a balanced combination of high flux density and stable performance, especially beneficial in space-limited designs. Rather than oversizing magnet geometry to achieve holding force, designers can use N52 to meet performance targets and retain compact form.
Predictable Magnetic Behavior
In practical applications, engineers rely more on consistent field behavior than on isolated pull-force numbers. This magnet has been manufactured and magnetized to deliver repeatable performance across batches, which is important for production quality control and assembly consistency.
Integration-Friendly
Precision tolerances and multiple magnetization options allow N52 magnets to be integrated into assemblies without additional adjustments to housing or tooling alignments. This is particularly useful in automated assembly lines and precision motion systems.
Typical Application Scenarios
N52 neodymium magnets are commonly used in:
- Electric Motors & Generators: Rotors, stators, magnetic circuits requiring uniform flux
- Sensors & Actuators: Magnetic field sources in position or speed sensing devices
- Industrial Fixtures: Magnetic separators, holding plates, or jigs in production lines
- Automation & Robotics: Magnetic coupling and retention components
- Consumer/Electronics: Magnetic modules in compact devices
These use cases benefit from a balance of force, volume, and stability, rather than just raw magnetic pull.
Procurement & Customization Support
We support bulk orders and OEM partnerships for high-volume or long-term projects. Custom service options include:
- Dimension and shape customization (block, disc, ring, or special profiles)
- Magnetization direction and pole pattern specification
- Alternative plating/coating for humidity, wear, or chemical exposure
- Packaging tailored for production line delivery
Early provision of CAD drawings and operating environment details helps ensure correct magnet selection and minimizes revision cycles.
Samples can be supplied for testing before placing bulk orders to confirm fit, field strength, and integration readiness.
Quality Documentation
Each batch can be supplied with:
- Dimensional inspection data
- Magnetic property reports (flux density, coercivity)
- Coating quality verification
- Batch traceability certificates
This documentation supports incoming inspection and quality assurance in manufacturing environments.
FAQ
Q: What distinguishes N52 from lower grades like N35 or N42?
A: N52 has higher energy density, providing stronger magnetic fields in the same size magnet, which is useful for compact or advanced designs.
Q: Can custom magnetization patterns be produced?
A: Yes - axial, radial, multi-pole, or other patterns can be configured based on your drawings.
Q: Are sample quantities available before placing larger orders?
A: Yes - sample magnets can be supplied for preliminary evaluation before committing to Bulk Orders.
