Import Excellent Quality Sintered Ndfeb Magnetic Cylind — Buy in Bulk from Supplier in China

The product is a sintered neodymium-iron-boron (NdFeB) magnetic cylinder, manufactured using strip casting and HDDR technology to achieve dense microstructure and aligned magnetic domains. The listing confirms high magnetic strength and thermal stability, with no exact grade or Br value provided, but the material type aligns with N35 to N52 commercial grades commonly used in industrial motors. Dimensions and tolerances are not specified, but standard sintered NdFeB cylinders typically have diameters from 5mm to 50mm and lengths from 5mm to 100mm with ±0.05mm dimensional tolerances.

These magnets are sintered, not bonded, meaning they offer higher energy products and better temperature resistance than bonded alternatives. The material is typically coated with nickel-copper-nickel (Ni-Cu-Ni) for corrosion protection, though the listing does not confirm coating type. Standard operating temperatures range from 80°C to 220°C depending on grade, with higher grades like N42SH offering improved coercivity at elevated temperatures. The absence of a specified grade suggests the product may be offered in multiple grades, common among suppliers serving diverse motor and sensor applications.

End users include manufacturers of brushless DC motors, servo systems, magnetic couplings, and wind turbine generators. Buyers typically require consistent flux output and mechanical precision for integration into rotating assemblies. Trade terms are not stated, but standard practice for this product includes carton packaging with anti-magnetic shielding, bulk palletization, and shipment under FOB Shanghai or CIF terms. MOQ and lead time are not listed; buyers should request these directly with the supplier.

Hefei Super Electronics Co., Ltd. is a supplier based in Hefei, Anhui Province, China, with a registered address at Room1401, Building20, Zhong Jie Crystal. The listing confirms the company is classified as an imported supplier with harbor trust tier, indicating verified export capability and compliance with basic trade documentation standards. No information is provided regarding company size, years in operation, production capacity, or client list.

The supplier’s profile does not state certifications, workforce size, or revenue. The absence of response rate and average response time suggests limited buyer interaction history on the platform. The company appears to focus on permanent magnet products, particularly sintered NdFeB, as reflected in the product listing. Buyers should confirm technical capabilities and quality control processes directly before placing orders.
