Disc neodymium magnet permanent magnets from Sky Magnetech( Ningbo) Co., Ltd. are sintered NdFeB components with residual flux densities exceeding 14,000 gauss in higher grades, produced for industrial automation and electronic device manufacturing. These magnets are available in grades N35 through N52, with standard diameters from 3mm to 120mm and thicknesses from 0.5mm to 25mm. The material is processed under controlled atmospheres to minimize oxidation and ensure consistent magnetic properties across batches.
Surface treatments include nickel, zinc, or epoxy coatings, selected based on environmental exposure and mechanical stress. Nickel plating is standard for most applications, offering a balance of durability and cost. These magnets are not inherently waterproof and should not be used in submerged environments without additional encapsulation. Their mechanical brittleness requires careful handling during assembly to avoid chipping or cracking under impact.
End users include manufacturers of electric vehicle components, hard disk drives, magnetic separators, and industrial sensors. Orders are commonly placed in quantities of 5,000 to 50,000 units per shipment, packed in bulk or tray formats depending on size. Trade is typically conducted under FOB Ningbo terms, with lead times of 20 to 30 days. Buyers should confirm whether the supplier provides magnetization axis alignment documentation and batch traceability.

Sky Magnetech( Ningbo) Co., Ltd. is a manufacturer located in Yinzhou District, Ningbo, China, with a physical address registered at Rm 1202, Jinshan Mansion, No.555 Changshou South Road. The supplier is identified as a direct producer of sintered neodymium magnets, with no public data indicating third-party sourcing or trading intermediaries. Its trust tier is harbor, indicating factory verification but no third-party audit reports are disclosed.
No information is provided regarding workforce size, production capacity, certifications, or export history. The supplier's response rate is zero and average response time is unrecorded, suggesting minimal customer service engagement. Buyers must assume this is a production facility without formal quality assurance documentation unless explicitly confirmed. All technical claims should be validated through independent testing prior to large-scale procurement.
Sintered NdFeB disc magnets are the most widely used rare earth permanent magnets in industrial applications including motors, generators, sensors, and consumer electronics. Available in high-grade options such as N35 through N52, these magnets offer exceptional magnetic strength with residual flux density exceeding 14,000 gauss. As a key input material for precision manufacturing, neodymium magnets are sourced globally by OEM manufacturers and trading firms, with pricing sensitive to rare earth commodity markets.

Verify the magnetic grade, coating type, and dimensional tolerances before placing an order. Confirm the magnetization direction and request a flux map for each batch. Do not assume N52 performance without independent verification - some suppliers label lower grades as N52. Test a sample under actual operating conditions to validate holding force and thermal stability.
Lead time is typically 20 to 30 days after deposit, with FOB Ningbo as the standard incoterm. Payment terms are usually 30% advance, 70% against shipping documents. Confirm whether the supplier provides export documentation, including certificate of origin and material compliance statements. For large orders, request a production timeline with inspection checkpoints.
Perform incoming inspection using a gauss meter to verify flux density and a pull tester for adhesion strength. Check plating integrity with a salt spray test or copper sulfate spot test. Retain a sample from each shipment for quality comparison. Ensure packaging prevents magnetic interference with other goods and includes moisture absorbers if stored long-term.
