Buy & Import Custom Magnet Coatings from Anhui Hanhai New Material Co., Ltd. - Wholesale Supply

Custom magnet coatings for neodymium iron boron (NdFeB) magnets are applied to prevent corrosion and maintain magnetic performance in demanding environments. Anhui Hanhai New Material Co., Ltd. provides coatings including nickel, zinc, epoxy, and gold, applied to magnets with compositions of 64-66% iron, which are inherently susceptible to oxidation. These coatings are not decorative but functional, preserving coercivity and surface integrity under exposure to moisture, salt spray, acids, or elevated temperatures.

The standard coating thickness ranges from 8 to 25 micrometers depending on the material and application. Nickel coatings are most common for general industrial use, offering good corrosion resistance and a smooth finish. Zinc coatings are economical and suitable for dry environments, while epoxy provides superior protection against saltwater exposure. Gold plating is used in medical or high-reliability electronics where biocompatibility and low contact resistance are required. These coating types align with industry standards for rare earth magnet protection, though exact thickness and adhesion are specified per customer request.

These coated magnets are purchased by manufacturers of electric motors, sensors, wind turbine generators, hard disk drives, and consumer audio devices. Buyers typically require consistent coating uniformity, minimal pinholes, and compliance with ASTM B117 salt spray testing or ISO 9227 standards. Trade terms are negotiated per order; packaging is usually anti-corrosion sealed with desiccant, and bulk shipments are palletized. Lead times vary with customization level, and minimum order quantities are not publicly listed but are typically above 1,000 pieces for custom geometries.

The company specializes in custom magnet production and coating services, with documented ISO9001 certification for quality management. The supplier does not claim to hold ISO14001, IATF 16949, or REACH compliance, nor does it list any export history or client names.

Response metrics show no recorded response rate or average response time, indicating limited or no active trade engagement on the platform. The supplier does not publish financial data, workforce size, or years in operation. Its credibility derives from its manufacturing footprint and stated certification, not from marketing claims or third-party endorsements. Buyers should verify coating specifications directly, as public documentation is limited to product descriptions and general facility details.

Custom magnet coating services for neodymium iron boron (NdFeB) permanent magnets provide essential corrosion and oxidation resistance for industrial applications. These rare earth magnets with protective coatings such as nickel, zinc, or epoxy are widely used in motors, generators, sensors, and consumer electronics. Sourced primarily from China, coated neodymium magnets are a high-demand import commodity for manufacturers seeking durable magnetic components at competitive pricing.

Frequently Asked Questions About Custom Magnet Coatings from Anhui Hanhai New Material Co., Ltd.
Adhesion is typically verified using ASTM B571, which involves applying pressure-sensitive tape and peeling it off after 24 hours. A合格 result shows no coating delamination. This test ensures the coating remains bonded under mechanical stress during assembly or operation.

Sourcing Custom Magnet Coatings from Anhui Hanhai New Material Co., Ltd. - China Import Guide

Before placing an order, verify the exact coating type, thickness tolerance, and adhesion test results with the supplier. Request a sample batch tested to ASTM B117 or ISO 9227 for salt spray resistance, especially if the magnet will be used in humid or coastal environments. Confirm that the coating does not interfere with magnetic field alignment in your assembly, as even minor surface irregularities can affect performance in sensors or motors.

Lead time for custom coatings is typically 2 to 4 weeks after design approval, depending on batch size and complexity. Incoterms are usually FOB Anqing Port or CIF destination, but must be confirmed per order. Payment terms commonly involve 30% advance and 70% against shipping documents. Buyers should ensure the supplier provides a material compliance statement for each shipment, especially if the product enters regulated markets like the EU or US medical device supply chains.

Quality verification should include visual inspection for coating defects, thickness measurement with a magnetic induction gauge, and adhesion testing on a sample per batch. Request a certificate of conformity referencing ISO9001 and the specific coating specification used. For critical applications, arrange third-party inspection before shipment to validate porosity, salt spray performance, and dimensional stability. Documentation must accompany each shipment to avoid customs delays.
