SmCo magnets are produced by alloy melting, powder milling, pressing in a magnetic field and vacuum sintering, followed by precision grinding.
The process is similar to NdFeB but uses a different alloy system and higher sintering temperatures.

FAQ
SmCo Magnet Production Flow — FAQ
Why is SmCo pressed in a magnetic field?
Orienting the magnetic particles during pressing aligns the easy axis, maximizing the output of the finished magnet.
How are SmCo magnets quality checked?
Dimensions, magnetic flux, density and, for critical applications, temperature cycling tests are performed before shipment.
Do you provide free samples for testing?
Yes, sample orders are welcome. Send your drawing or specification together with the intended application so our engineers can recommend the correct grade, magnetization direction and coating before we prepare samples.
Can the factory produce to my drawing with special tolerances?
Yes. We machine, grind and inspect to customer drawing tolerances. For sintered NdFeB the standard machining tolerance is ±0.05 mm and can be tightened to ±0.02 mm with diamond grinding where the geometry allows.
