Long strip rectangular strong magnetic bar is a strip-shaped NdFeB permanent magnet product with long strip rectangular structure, which is processed from high-performance sintered NdFeB magnetic materials through cutting, grinding and surface treatment. The product is characterized by long strip shape, large flat area and regular structure, with uniform overall magnetic force and strong linear magnetic field distribution. As one of the most basic and widely used special-shaped magnets, the long strip strong magnetic bar can realize long-distance linear magnetic adsorption and magnetic field coverage, and is suitable for linear fixing, strip positioning and long-range magnetic induction scenarios that circular and square magnets cannot adapt to. The product has complete size specifications, and can be customized in length, width, thickness and tolerance according to actual working needs, with high flexibility and strong applicability.

In terms of core performance advantages, the long strip rectangular strong magnetic bar retains the super strong magnetic force of NdFeB materials, with high remanence and magnetic energy product, strong single-point adsorption force and large overall magnetic coverage area. The strip linear structure makes the magnetic field distributed in a long linear shape, which can realize uniform magnetic force coverage in the long strip range, solving the problem of uneven magnetic force and small coverage area of block magnets in linear working scenarios. The product has stable magnetic performance, strong anti-demagnetization ability, no magnetic attenuation after long-term use, and can maintain stable adsorption and induction performance in continuous working state. After precision grinding treatment, the surface of the magnetic bar is flat and smooth, the edges and corners are neat, the dimensional accuracy is high, and the fitting degree with the fixed surface is excellent. Through professional electroplating anti-corrosion treatment, the magnetic bar has good oxidation resistance, corrosion resistance and wear resistance, adapting to indoor, outdoor, humid and dusty industrial working environments, with long service life and low failure rate.

Long strip rectangular strong magnetic bars are widely used in industrial fixing, equipment assembly, magnetic separation screening, intelligent equipment and other fields. In industrial production and processing, they are used for linear positioning of production line workpieces, strip fixing of mechanical accessories and auxiliary assembly of long structural parts, improving the linear accuracy and assembly efficiency of equipment. In the magnetic separation industry, long strip strong magnetic bars are assembled into magnetic separation frames and magnetic separation equipment, used for iron removal and impurity separation of granular, powdery and liquid materials in food, chemical, mining and building materials industries, effectively removing iron impurities in materials and improving product purity. In the field of household appliances and electronic equipment, they are applied to strip magnetic fixing of refrigerators, air conditioners, washing machines and other household appliances, as well as linear magnetic induction components of intelligent electronic equipment. In addition, long strip rectangular strong magnetic bars are also commonly used in advertising display fixing, warehouse storage sorting, mechanical equipment damping positioning, automobile interior fixing and teaching experimental equipment. Its unique linear magnetic field advantage makes it the preferred magnetic component for long-range linear fixing and magnetic separation scenarios.
