Import Arc Bonded Ndfeb Magnets — Buy in Bulk from Supplier in China

Arc Bonded NdFeB Magnets from China-Base Ningbo Foreign Trade Co., Ltd. are compression-bonded permanent magnets manufactured from isotropic neodymium-iron-boron (NdFeB) powder mixed with epoxy resin binders. The compression process yields magnets with higher magnetic density than injection-moulded alternatives, though it limits geometric complexity to simpler shapes like arcs, rings or blocks. These magnets are coated with epoxy or parylene for superior corrosion resistance, making them suitable for industrial and automotive environments exposed to solvents, fluids and temperature extremes.

The magnets exhibit typical magnetic properties such as a maximum energy product (BHmax) ranging from 8 to 12 MGOe, intrinsic coercivity (Hcj) of 12 to 16 kOe and remanence (Br) of 6,000 to 7,500 Gauss, depending on the grade of NdFeB powder used. Standard operating temperatures span from -40°C to 150°C, with some grades extending to 165°C for high-temperature applications. The epoxy coating ensures a smooth, defect-free surface with no bubbles, cracks or delamination, critical for applications requiring tight dimensional tolerances.

Primary applications include mini-motors, auto motors, air-conditioner compressors, sensors, automatic control devices and telecommunications equipment. The magnets are supplied as single-pole or multi-pole oriented components, with typical dimensional tolerances of ±0.1 mm for critical features. Buyers in the automotive and electronics sectors prioritise these magnets for their high magnetic strength-to-weight ratio and stability in mass production. Trade terms and packaging are confirmed directly with the supplier, with ocean, land and air freight options available.

China-Base Ningbo Foreign Trade Co., Ltd. is headquartered in Ningbo, Zhejiang Province, at N0.666 Tiandong South Road, Yinzhou District. The company specialises in the export of bonded NdFeB magnets and other magnetic materials, catering to industries such as automotive, electronics and industrial automation. Its product portfolio includes compression-bonded and injection-moulded magnets, with a focus on high-volume, precision applications.

The supplier operates under China’s imported tier classification and holds a harbor trust tier, indicating a baseline trade credibility. While the listed response rate and average response hours are currently zero, this may reflect a lack of recent activity rather than capability. The company does not provide explicit details on production capacity, certifications or client references in its profile, so buyers should request this information directly to assess suitability.
