Micro 1mm small size NdFeB magnets are ultra-precision miniature permanent magnetic materials developed for miniaturization, precision and lightweight development trend of modern electronic and intelligent equipment. With a minimum dimensional accuracy of 1mm, including 1mm diameter circular magnets, 1mm thick square magnets, 1mm cylindrical and special-shaped tiny magnets, they break the size limitation of traditional NdFeB magnets and fill the market gap of high-precision miniature magnetic components. These tiny magnets are processed by advanced ultra-fine cutting, wire cutting and precision grinding technology, which effectively avoids edge collapse, burrs and dimensional errors in the processing of small-size magnets, and the dimensional tolerance is strictly controlled within ±0.01mm, reaching industrial high-precision level.

Despite their tiny size, the micro 1mm NdFeB magnets retain the excellent magnetic characteristics of high-performance NdFeB materials, with high remanence, strong magnetic suction and stable magnetic field distribution. Compared with ordinary ferrite miniature magnets, they have more than 3 times stronger magnetic force under the same volume, realizing ultra-small size and super strong magnetic performance, which is irreplaceable in micro-precision equipment. The products adopt high-density sintering process, with uniform internal material structure, no internal pores, stable magnetic properties, no demagnetization under normal temperature working environment, and consistent magnetic field output of each batch of products, ensuring the assembly consistency of precision equipment.

In terms of surface treatment, micro 1mm small size magnets support diversified anti-corrosion treatments such as nickel plating, zinc plating and epoxy coating according to user needs. The ultra-thin protective coating will not affect the overall dimensional accuracy and assembly gap of the magnet, while effectively improving the anti-oxidation and anti-corrosion ability of the tiny magnet. The product has excellent adaptability to assembly, with smooth surface, no burrs, uniform stress, suitable for glue bonding, embedded assembly, snap installation and other various assembly methods, and will not cause scratch damage to precision parts and circuit boards.

The application fields of 1mm micro NdFeB magnets are highly concentrated in high-precision micro-equipment, including wearable electronic devices such as smart watches, Bluetooth headsets and smart bracelets, micro-sensors, micro-motors, precision instruments, medical miniature equipment, optical devices, 3C electronic accessories and intelligent robot micro-components. In Bluetooth headsets, tiny magnets are used for magnetic attraction closing and structural fixation; in medical micro-detection equipment, they provide stable magnetic field support for precision detection; in micro-vibration motors, they drive high-frequency vibration operation. With the continuous miniaturization of electronic products, micro 1mm small size NdFeB magnets have become core basic components of high-end precision manufacturing, providing reliable magnetic support for the lightweight, miniaturization and high-precision upgrading of modern intelligent equipment.
