Import China Neodymium Magnet Block — Buy in Bulk from Supplier in China

The China Neodymium Magnet Block offered by Shanghai Haoqi Magnetic Materials Co., Ltd. is a solid NdFeB magnet fabricated in block shape. The supplier lists grades ranging from N35 to N52 with a maximum working temperature of 80 °C, N35M‑N50M up to 100 °C, N33H‑N48H up to 120 °C, N33SH‑N45SH up to 150 °C, N28UH‑N38UH up to 180 °C and N28EH‑N35EH up to 200 °C. Dimensions are supplied on a custom basis according to the buyer’s drawing, and the standard dimensional tolerance is ±0.1 mm. Available surface treatments include zinc, nickel, gold, silver, epoxy and parylene coatings.

NdFeB magnets such as these consist primarily of neodymium, iron and boron, a composition that delivers high remanence and coercivity across the listed grades. In the magnet industry, a typical Br (residual flux density) for an N35 grade is about 1.2 Tesla, while typical coercive force (Hc) reaches 950 kA m‑1. The density of NdFeB material is usually around 7.5 g cm‑3, providing a high energy product for compact designs. The offered coating options improve corrosion resistance and are selected according to the operating environment.

These blocks are commonly used in electric vehicle motors, wind‑turbine generators, industrial automation equipment and high‑performance consumer electronics. Buyers such as OEMs and system integrators often request custom dimensions and specific coating to match design constraints. Shanghai Haoqi Magnetic Materials Co., Ltd. advises prospective importers to confirm minimum order quantities, lead‑time estimates and preferred Incoterms directly with the supplier.

Shanghai Haoqi Magnetic Materials Co., Ltd. is located at Room 635 Jrun Building, 1658 Husong Highway, Shanghai 201615, China. The company is classified as an imported tier supplier and carries a harbor trust tier, indicating it sources raw material or finished products for export. According to the listing, the firm has not recorded any response activity, with a response rate shown as 0 % and an average response time of zero hours. Their catalogue focuses on NdFeB magnets in a wide variety of shapes and custom dimensions.

The supplier’s public profile does not disclose specific minimum order quantities, pricing structures or lead‑time commitments.
