1. Product Knowledge

Q: What are neodymium magnets and how are they made?
A: Neodymium magnets are a type of rare-earth magnet made from an alloy of neodymium, iron, and boron (NdFeB). They are manufactured by pressing and sintering powdered alloy into shape, then magnetizing it with a strong electromagnetic field. This process creates one of the most powerful permanent magnets available today.

Q: What is the difference between N35, N45, and N52 magnets?
A: These codes refer to the magnet’s grade, which indicates its maximum energy product. The higher the number, the stronger the magnet. For example, N52 is the most powerful grade commonly available, while N35 is less powerful but often more cost-effective.

Q: How do I choose the right pull force?
A: Pull force depends on your application, the surface type, and the contact area. A smooth, thick steel surface allows the magnet to reach its full pull force, while painted or uneven surfaces reduce strength. We recommend choosing a magnet with a pull force at least 2–3 times higher than your required holding force for safety.

Q: What coatings are available for neodymium magnets?
A: Common coatings include Nickel-Copper-Nickel (NiCuNi) for corrosion resistance, Zinc for cost-effectiveness, and Epoxy for added moisture protection. The best choice depends on the environment – for outdoor or humid conditions, epoxy or plastic-coated magnets are recommended.

Q: What is the maximum temperature for neodymium magnets?
A: Most standard neodymium magnets can be used up to about 80°C (176°F). High-temperature grades (e.g., N35EH) can withstand up to 200°C (392°F) but have lower maximum strength.

Q: What’s the difference between axial and radial magnetization?
A: Axial magnetization means the magnetic poles are on the flat faces (top and bottom) of the magnet. Radial magnetization means the poles are arranged around the circumference. The choice depends on the application’s magnetic field requirements.

2. Applications & Safety

Q: How should I handle strong neodymium magnets?
A: Always handle them with care. Keep fingers away from the gap between two magnets, as the strong attraction can cause injury. Wear gloves and eye protection when handling large magnets.

Q: Are neodymium magnets safe near electronics?
A: No. Strong magnetic fields can damage electronic devices, magnetic storage media, and credit cards. Keep them at least 20 cm (8 inches) away from such items.

Q: Can neodymium magnets be used outdoors?
A: Yes, but they must be coated or sealed to prevent corrosion. Nickel coatings are adequate for dry environments, but epoxy or plastic-coated magnets are better for outdoor or wet use.

Q: Can I drill or cut neodymium magnets?
A: No, this is not recommended. Neodymium magnets are brittle and may shatter when drilled or cut. The dust is flammable and hazardous. Always order the required size directly from the supplier.

Q: How do I store strong magnets safely?
A: Store magnets with spacers between them to reduce magnetic attraction. Keep them away from children and pacemakers. Large magnets should be stored in sturdy containers.

Q: Can magnets be used for medical or therapeutic purposes?
A: We do not recommend using magnets for medical purposes. While some products are marketed for magnetic therapy, scientific evidence for their effectiveness is limited.

3. Ordering, Shipping & Service

Q: Do you ship magnets internationally?
A: Yes. We ship worldwide. Shipping times and costs depend on the destination and order size.

Q: Can I request custom sizes or shapes?
A: Yes. We can produce custom neodymium magnets according to your specifications, including size, shape, coating, and magnetization direction.

Q: How are magnets packaged for shipping?
A: Magnets are packaged with steel separators, foam padding, and cardboard to comply with safety regulations and prevent damage during transport.

Q: Are there any shipping restrictions for magnets?
A: Some carriers have restrictions on shipping large or strong magnets by air. We ensure all shipments meet transport regulations.

Q: Do you offer bulk discounts?
A: Yes. We provide competitive discounts for bulk orders. Please contact us for a custom quote.

Q: What payment methods do you accept?
A: We accept major credit cards, PayPal, and bank transfers. All transactions are processed securely.

Q: What is your return policy?
A: The right of withdrawal applies only to consumers (private individuals) and not to businesses. Consumers may return unused magnets in their original packaging within 14 days of delivery. Custom-made items are non-refundable.
