10 Frequently Asked Questions About Magnets

1. What is the strongest type of magnet? Neodymium (NdFeB) magnets are the strongest, with a maximum energy product (BHmax) up to 52 MGOe.
2. Can magnets lose their magnetism over time? Yes, through heat, physical shock, or exposure to opposing magnetic fields. NdFeB magnets lose about 0.1-0.5% per year at room temperature.
3. What is the working temperature for SmCo magnets? SmCo magnets operate up to 350°C, while NdFeB is limited to 80-200°C depending on grade.
4. Are ferrite magnets cheaper than NdFeB? Yes, ferrite magnets cost about $1-5/kg, while NdFeB costs $30-100/kg depending on grade and coating.
5. How are magnets coated to prevent corrosion? Common coatings include nickel-copper-nickel, zinc, epoxy, and parylene. NdFeB requires coating due to high iron content.
6. What is the difference between sintered and bonded magnets? Sintered magnets have higher magnetic performance but are brittle. Bonded magnets are easier to shape but have lower energy product.
7. Can I drill or machine a magnet? It is not recommended due to brittleness. Custom shapes should be ordered from the factory.
8. What is the recycling rate for rare earth magnets? Less than 5% currently. New technologies are being developed for urban mining.
9. How do I choose between NdFeB and ferrite? Ferrite is cost-effective for low-performance applications. NdFeB is for high-power density needs like motors.
10. Are magnets safe to ship by air? Yes, but they must be packed in mu-metal shielding to avoid interference with aircraft systems.

Procurement Considerations for Magnets

When sourcing magnets from factories, consider these factors:

• Grade and Tolerance: Specify N35, N52, or custom grades. Request magnetic flux density (Br), coercivity (Hcj), and maximum operating temperature.
• Coating and Corrosion Resistance: For NdFeB, require Ni-Cu-Ni or epoxy for outdoor use. For ferrite, standard coating is sufficient.
• Magnetization Pattern: Axial, radial, or multi-pole. Provide drawings for custom magnetization.
• Quality Certifications: ISO 9001, IATF 16949 for automotive, and REACH/RoHS compliance for European markets.
• Lead Time: Chinese factories typically deliver in 15-30 days for standard sizes. Custom shapes take 30-45 days.
• Minimum Order Quantity (MOQ): For NdFeB, MOQ is often 500-1000 pieces. Ferrite MOQ is higher due to tooling costs.

Product Pricing for Magnets

Prices vary by type, grade, and quantity. Below are approximate ranges for bulk orders (10,000+ pieces) from Chinese factories in 2025.

Magnet Type	Grade	Size Example	Price per Piece (USD)
NdFeB Sintered	N35	10x10x5 mm	$0.15 – $0.30
NdFeB Sintered	N52	10x10x5 mm	$0.45 – $0.80
Ferrite (Ceramic)	C8	30x20x10 mm	$0.05 – $0.10
