Sintered NdFeB permanent magnets from China-Base Ningbo Foreign Trade Co., Ltd. are engineered from a neodymium-iron-boron rare earth alloy, available in grades N35 through N52. These magnets deliver the highest commercially available magnetic flux density, with coercivity and thermal stability enhanced through precise sintering and post-processing. The supplier’s material specification confirms the alloy composition as NdFeB, with grade-dependent energy products and demagnetisation resistance tailored for industrial applications.
The magnets are produced to meet the exacting demands of EV motors, wind turbine generators, and high-precision electronics, where compact size and high magnetic strength are critical. Standard industry grades like N35 to N52 are defined by their maximum energy product (BHmax), which typically ranges from 33 to 50 MGOe for these grades, with higher grades offering superior performance at elevated temperatures. Surface treatments such as nickel or epoxy coatings are typical to mitigate corrosion, a known limitation of uncoated NdFeB alloys.
Primary buyers include manufacturers in the automotive, renewable energy, and industrial automation sectors, where these magnets are integrated into rotors, sensors, and actuators. The product is traded in bulk, often with custom shapes and tolerances to match assembly requirements. For sourcing, buyers should confirm dimensional tolerances, coating specifications, and magnetic orientation, as these directly impact performance in end-use applications.

Before ordering sintered NdFeB magnets from China-Base Ningbo Foreign Trade Co., Ltd., verify the exact grade and magnetic properties required for your application. Request a material certificate that includes BHmax, Br, and HcJ values, as well as the coating type and thickness. Confirm whether the supplier can provide third-party testing reports, such as those from SGS or Bureau Veritas, to validate the material’s performance.
Logistics for these magnets require careful planning due to their strong magnetic fields, which can interfere with electronic devices and other cargo. Confirm the Incoterms (e.g., FOB Ningbo) and packaging standards to ensure safe transport. Lead times for custom grades or shapes may vary, so request a production schedule and shipping timeline. Payment terms, such as TT or LC, should also be agreed upon in advance to avoid delays.
Quality checks should include visual inspection for surface defects, coating uniformity, and dimensional accuracy using calipers or micrometers. For critical applications, perform magnetic property tests, such as flux density or coercivity measurements, using a teslameter or hysteresis graph. Request the supplier’s quality control process documentation, including inspection reports and test methods, to ensure compliance with your specifications.
