N38 high-magnetic-force NdFeB magnets are upgraded medium-grade sintered NdFeB permanent magnets developed on the basis of N35 magnets, with a standard magnetic energy product reaching 38MGOe, achieving a significant improvement in magnetic density and adsorption force compared with N35 grade. Adopting optimized formula batching and precision sintering process, N38 NdFeB magnets have higher residual magnetism and stronger magnetic permeability, with more concentrated magnetic field and more stable magnetic output. This grade is positioned in the middle-end industrial field, suitable for scenarios requiring higher magnetic force than conventional basic magnets while controlling comprehensive costs, and is one of the most widely used magnetic materials in medium-end precision equipment.

In terms of performance advantages, N38 NdFeB magnets have a residual magnetic flux density of 1.22-1.26T, with effectively improved magnetic suction and magnetic induction sensitivity compared with N35 grade. The product maintains excellent anti-demagnetization performance and structural stability at normal temperature, with a maximum working temperature of 80°C, adapting to most indoor industrial and precision electronic working environments. Through optimized sintering and tempering technology, the internal structure of the magnet is denser, with fewer internal pores, higher product consistency, and more uniform batch magnetic performance. The dimensional tolerance after precision processing is small, with smooth surface and good assembly compatibility. Conventional zinc plating, nickel plating, and epoxy coating treatments are available to enhance environmental adaptability, resisting oxidation and corrosion in long-term working processes and ensuring no obvious magnetic attenuation within the service cycle.

N38 high-magnetic-force NdFeB magnets are mainly used in medium-end industrial equipment, precision electronic products, and intelligent civilian equipment with higher magnetic force requirements. In the intelligent hardware industry, they are core magnetic components for smart wearable devices, intelligent door locks, sensor equipment, and Bluetooth intelligent devices, providing sensitive and stable magnetic induction and strong adsorption positioning. In the automation industry, N38 magnets are applied to precision tooling positioning, automated mechanical arm auxiliary adsorption, and assembly line precision fixing, improving the stability and accuracy of automated equipment operation. In the motor industry, they serve as magnetic steel for small and medium-sized high-efficiency motors, micro servo motors, and household appliance drive motors, optimizing motor operating efficiency. In addition, they are extensively used in medical auxiliary equipment, precision instrument accessories, automotive electronic components, and customized medium-end magnetic products. With higher magnetic performance and moderate price, N38 NdFeB magnets fill the performance gap between basic N35 magnets and high-end high-grade magnets, becoming the optimal choice for medium-end industrial product upgrading and precision magnetic matching.
