Compared with other permanent magnet materials, samarium cobalt (SmCo) magnets boast outstanding magnetic properties, featuring ultra-high Curie temperature, excellent coercivity, and remarkable temperature stability.

They also exhibit strong corrosion resistance and high mechanical strength, maintaining stable performance even under harsh environmental conditions.

These exceptional characteristics make samarium cobalt permanent magnets widely applied in high-end industrial equipment and aerospace technologies.

Typical applications include high-temperature motors, sensors, traveling wave tubes, aerospace instruments, and magnetic drive devices, and more.

Processing Technologies We Provide:

Mechanical Processing

After sintering, SmCo magnets undergo grinding, cutting and other mechanical processing.

We are equipped with various grinders, slicers and multi-wire cutting machines, enabling precise machining to meet your final shape and tolerance requirements.

EDM Machining

EDM is ideal for processing hard SmCo magnets, allowing complex cutting and shaping with minimal mechanical stress, thus reducing the risk of cracking. We own high-speed and medium-speed wire-cut EDM machines to support profile cutting of SmCo materials.

Laser Cutting

​​​​​​​Laser cutting is suitable for ultra-thin parts (≤3mm) requiring complex shapes, with high precision and minimal material waste. However, it may not be feasible for thick products and can cause thermal damage to the edges.

​​​​​​​Special Profile Grinding

​​​​​​​With custom grinding wheels and fixtures, we perform precision grinding on magnet surfaces to achieve high surface finish and dimensional accuracy.

​​​​​​​Drilling

​​​​​​​Due to SmCo’s high hardness and brittleness, drilling requires specialized diamond tools and custom fixtures, and is only feasible for small-diameter holes (≤3mm) to avoid chipping. 

​​​​​​​Custom Shapes

​​​​​​​We can produce SmCo magnets into various special shapes, including rings, flats, embedded designs and more.
