Rare Earth Permanent Magnet

Sintered NdFeB is a rare-earth permanent magnet material renowned for its extremely high energy product and excellent magnetic properties. It is small in size and light in weight, yet it can provide a stronger magnetic field than other magnetic materials. Additionally, it has a high coercivity and strong resistance to demagnetization.

Flexible NdFeB is a new type of flexible bonded permanent magnet material that combines the high magnetic properties of NdFeB with the processability of flexible materials. This material is typically prepared using rubber-based organics as binders, rapidly quenched NdFeB powder as filler, and auxiliary processing additives, through the production process of rubber-based products. Flexible NdFeB not only exhibits high magnetic and mechanical properties but is also easy to process into various complex shapes such as flexible bonded magnetic plates, strips, and rings, thereby meeting a wide range of application needs. Additionally, it has advantages such as good impact resistance, resistance to fragmentation, and the ability to be embedded in metal or non-metal parts for integral molding.

Molded NdFeB is a strongly magnetic material composed of elements such as neodymium, iron, and boron, prepared through a molding and pressing process. It boasts an extremely high energy product and magnetic energy density, making it one of the most powerful commercialized permanent magnet materials available. Molded NdFeB is corrosion-resistant, temperature-stable, and has good processability, making it widely applicable in various fields such as electronic devices, the automotive industry, and medical equipment.

Injection-molded NdFeB magnets are a type of bonded NdFeB magnets produced through an injection molding process. They are made by mixing NdFeB magnetic powder with thermoplastic binders (such as nylon, PPS, etc.) and a small amount of polymer additives (such as coupling agents, lubricants, antioxidants, etc.). Injection-molded NdFeB magnets feature high dimensional accuracy, suitability for complex shapes, elimination of the need for subsequent processing steps, and ease of mass production. They can also be directly injection-molded in combination with components made of other materials to form assemblies. Additionally, injection-molded NdFeB magnets exhibit good toughness and corrosion resistance.

Neodymium-Iron-Boron laminations are a type of laminated structure made from Neodymium-Iron-Boron magnetic material, commonly used to enhance the magnetic field effect of motors, thereby improving overall performance and efficiency. This laminated structure is precisely stacked with magnetic sheets of various shapes, quantities, and materials, aiming to strengthen the magnetic field intensity of the motor, optimize the magnetic field distribution, reduce magnetic field gradients and magnetic clamping losses, and ensure more stable and reliable motor operation. In the manufacturing process, techniques such as pressing, injection molding, extrusion, and winding can be employed to ensure precise shaping of the lamination and meet complex design requirements. Neodymium-Iron-Boron lamination are widely favored for their high magnetic energy product, strong magnetization force, and excellent corrosion resistance, especially in applications where high-performance permanent magnetic materials are required.
