NdFeB micro magnetic steel refers to ultra-small size precision NdFeB permanent magnet components, which are miniaturized, refined and high-precision processed on the basis of conventional NdFeB magnet materials. The size of this type of magnetic steel is usually in the millimeter or even sub-millimeter level, with ultra-small thickness, ultra-fine diameter and ultra-precise dimensional tolerance, and it is a core magnetic component dedicated to miniaturized, lightweight and high-precision electronic and mechanical equipment. Made of high-purity NdFeB raw materials through ultra-fine powder making, high-precision molding, low-deformation sintering and micro-precision grinding processes, NdFeB micro magnetic steel overcomes the problems of large size, low precision and poor consistency of traditional magnets, and meets the strict requirements of high-end precision equipment for magnetic component size, performance and stability.

In terms of precision and performance advantages, NdFeB micro magnetic steel has extremely high dimensional accuracy, with the dimensional tolerance controlled within ±0.01mm, and the flatness, verticality and surface smoothness of the product reach the industrial high-precision level. While maintaining ultra-small size, it retains the high magnetic energy product and strong magnetic force characteristics of NdFeB materials, with concentrated magnetic field and stable magnetic performance, no magnetic attenuation in long-term use, and good anti-demagnetization ability. The product can adapt to high-frequency working environments, with stable magnetic induction performance, and can accurately complete magnetic induction, positioning, transmission and other functions in micro-equipment. In addition, through professional surface treatment processes such as ultra-thin nickel plating and passivation, the micro magnetic steel has excellent anti-oxidation and anti-corrosion capabilities, avoiding rust and performance degradation caused by tiny surface defects in micro-size state, and ensuring the long-term stable operation of precision equipment. According to the demand of miniaturized equipment, NdFeB micro magnetic steel can be processed into micro-square, micro-circular, micro-cylindrical, micro-ring and other special-shaped structures, with flexible molding and strong customization.

NdFeB micro magnetic steel is mainly used in high-end precision manufacturing fields that require miniaturization and high sensitivity. In the consumer electronics industry, it is widely used in mobile phone mini vibration motors, fingerprint identification modules, camera lifting and focusing components, TWS Bluetooth headset magnetic components, smart watch sensor magnets, etc., which is the key material to realize the lightweight and intelligent functions of electronic products. In the field of precision medical equipment, micro magnetic steel is applied to miniature medical sensors, minimally invasive surgical instrument positioning components, portable medical detection equipment, realizing precise magnetic induction and micro-positioning. In industrial automation, it is used in micro proximity switches, miniature magnetic encoders, precision servo motors and micro transmission equipment, improving the control accuracy and response speed of automated equipment. In addition, NdFeB micro magnetic steel also plays a key role in aerospace precision instruments, robot micro-joint sensors, automotive electronic precision components and other high-end fields. With the continuous miniaturization and precision development of intelligent equipment, the market demand for high-precision NdFeB micro magnetic steel is increasing year by year, and it has become an important supporting material for the upgrading of high-end precision manufacturing industry.
