Large industrial super-sized NdFeB magnets are heavy-duty high-performance permanent magnetic materials customized for large industrial equipment, heavy machinery and large energy equipment, breaking the size limit of conventional small and medium-sized NdFeB magnets. This series of products covers super-large specifications such as large square blocks, large cylinders, large fan-shaped and large special-shaped magnets, which are integrally sintered and processed by professional large-scale sintering equipment, avoiding the performance loss and structural instability caused by magnet splicing. The maximum single-piece size can reach several hundred millimeters, and the product density is high, the structure is compact, and the overall magnetic field is uniform, meeting the strong magnetic force and stable operation requirements of large industrial equipment.

Different from ordinary small magnets, large industrial super-sized NdFeB magnets adopt optimized industrial-grade high-energy product magnetic steel formula, with high magnetic energy product, high coercivity and high remanence, and can provide super strong and stable magnetic suction and magnetic field output in a large area. The products have excellent anti-demagnetization ability, can resist strong external magnetic field interference and mechanical vibration, and maintain long-term stable magnetic performance in high-load and continuous working industrial scenarios. After strict high-temperature aging treatment and magnetic stability treatment, the magnetic attenuation rate is extremely low, which can adapt to long-term continuous operation of industrial equipment for more than 10 years.

In the production process, super-sized NdFeB magnets adopt integrated integral molding technology, with strict control of raw material ratio, sintering temperature, holding time and cooling process, ensuring the uniformity of internal material structure of large-size magnets and avoiding quality problems such as internal cracks, magnetic deviation and performance difference in different areas caused by oversized volume. The surface is treated with thickened nickel plating, heavy-duty epoxy coating or waterproof and anti-corrosion special treatment, which has super strong wear resistance, corrosion resistance and weather resistance, and can adapt to harsh industrial environments such as high temperature, high humidity, heavy dust and chemical corrosion.

This type of magnet is widely used in heavy industrial fields, including large wind power generators, large industrial motors, mining magnetic separation equipment, magnetic suspension equipment, large mechanical fixture equipment, port magnetic cranes, metallurgical magnetic separation equipment and new energy power generation equipment. In wind power generation, super-large NdFeB magnets are used as the core magnetic components of permanent magnet generators, supporting high-power power generation and stable operation of wind turbines; in mining and metallurgical industries, they realize efficient separation of minerals and removal of iron impurities through strong magnetic field; in port handling machinery, they provide super magnetic suction for lifting steel materials. Large industrial super-sized NdFeB magnets are the core magnetic foundation of heavy industrial equipment, helping major industrial equipment improve operating efficiency, reduce energy consumption and enhance operational stability, and play an indispensable role in industrial upgrading and new energy equipment manufacturing.
