Disc neodymium magnets from Sky Magnetech( Ningbo) Co., Ltd. are sintered NdFeB permanent magnets manufactured to industrial standards, with magnetic grades ranging from N35 to N52 and surface coatings of nickel or zinc for corrosion protection. These magnets are produced using precise sintering techniques to ensure consistent magnetic flux density and dimensional accuracy, with typical diameters from 5mm to 100mm and thicknesses from 1mm to 20mm. The material composition is neodymium iron boron, offering the highest energy product of any commercially available permanent magnet, making them ideal for space-constrained applications.
The magnets are supplied in standard tolerances of ±0.05mm for diameter and ±0.1mm for thickness, which align with typical industry norms for precision assemblies. Surface plating is applied to prevent oxidation, as bare NdFeB is prone to corrosion in humid environments. Nickel plating is the most common, offering good durability and appearance, while zinc plating is used for cost-sensitive applications. These magnets are not suitable for continuous operation above 80°C without grade-specific thermal stabilization, and demagnetization risks increase significantly beyond their maximum operating temperature.
These magnets are primarily purchased by manufacturers of brushless DC motors, magnetic sensors, audio equipment, and automation systems in North America, Europe, and Southeast Asia. Buyers typically order in bulk quantities of 1,000 to 10,000 units per shipment, packed in anti-magnetic containers with individual spacers to prevent chipping. Trade terms are usually FOB Ningbo Port, with lead times of 15 to 25 days after order confirmation. Buyers should request a magnetization direction report and flux measurement data per batch to ensure performance consistency.

Sky Magnetech( Ningbo) Co., Ltd. is a manufacturing supplier based in Yinzhou District, Ningbo, China, with a registered address at Rm 1202, Jinshan Mansion, No.555 Changshou South Road. The company operates as a direct producer of sintered rare earth magnets, with no public information indicating third-party sourcing or trading activity. Its trust tier is classified as harbor, suggesting verified factory status but no independent audit certifications are disclosed in the listing.
The supplier does not publish details on annual production volume, workforce size, or client list. There is no indication of ISO certification, export history, or quality control documentation in the provided data. Response metrics show zero response rate and zero average response hours, which may indicate limited customer service capacity or automated listing management. Buyers should treat this as a factory-level producer and verify operational capacity directly before placing bulk orders.
Disc neodymium magnets are high-grade sintered NdFeB permanent magnets widely used in electric motors, generators, sensors, and consumer electronics. These rare earth magnets offer superior magnetic strength per unit size, typically supplied in N35 to N52 grades with nickel or zinc plating for corrosion resistance. As a key industrial component traded globally, disc neodymium magnets are exported in bulk packaging from major manufacturing hubs for use in automotive, renewable energy, and automation sectors.

Before ordering, verify the exact magnetic grade, coating type, and tolerance specifications in writing. Confirm the magnetization direction and whether the batch will include flux measurement data. Request a sample for pull-force testing against your application requirements. Do not rely on product titles alone - N42 and N42SH have vastly different thermal performance.
Lead time is typically 15 to 25 days after deposit, with FOB Ningbo as the default incoterm. Payment terms are commonly 30% advance, 70% against copy of bill of lading. Confirm whether the supplier handles export documentation, including commercial invoice, packing list, and material safety data sheet. For large orders, request a production schedule with milestones.
Conduct incoming quality checks using a gauss meter to verify flux density and a pull tester for holding force. Inspect plating for pinholes or peeling under magnification. Request a batch-specific test report for coercivity and maximum energy product. Retain samples from each shipment for future comparison. Ensure packaging includes desiccant if the magnets will be stored in humid environments.
