Have you ever seen such a tiny neodymium iron boron disc magnet? It measures just 0.5mm in diameter and 0.4mm in thickness.
Recently, we successfully completed sample production of a 0.5mm x 0.4mm neodymium iron boron disc magnet commissioned by a South Korean client. This specification represents one of the smallest sizes of sintered neodymium iron boron magnets that can currently be reliably manufactured.
The image below shows a neodymium disc magnet with a diameter of 0.5mm and a thickness of 0.4mm.

Miniature Round Rare Earth Magnet 0.5x0.4mm, Don't be fooled by how small they look—there are 600 of them.

In terms of applications, these miniature magnets are primarily used in precision electronics, precision sensors, wearable devices, micro-positioning structures, and similar fields.
With the ongoing advancement of microelectronics and precision manufacturing, the application scenarios for such micro-sized magnets continue to expand. Should your company require ultra-small, ultra-thin rare-earth permanent magnets, please feel free to contact us.
