FAQ
Q1: What are Neodymium Arc Magnets?
A: Neodymium arc magnets are high-strength permanent magnets made from NdFeB (Neodymium Iron Boron) with a curved (arc-shaped) design. They are widely used in motors, sensors, and industrial applications requiring strong magnetic fields in a compact form.
Q2: What is the strongest grade available for arc magnets?
A: Our N52-grade neodymium arc magnets offer the highest magnetic strength. We also provide lower grades (N35–N50) for applications with different temperature or cost requirements.
Q3: Can I get custom-sized Neodymium arc magnets?
A: Yes! We specialize in custom arc magnets with tailored dimensions (OD, ID, thickness, arc angle). Submit your requirements, and we’ll manufacture them to your exact specifications.
Q4: What coatings are available for corrosion protection?
A: Standard coating is nickel plating (most cost-effective). We also offer epoxy, gold, or zinc coatings for enhanced corrosion resistance in harsh environments.
Q5: What temperature can these magnets withstand?
A: Standard N52 magnets operate up to 80°C. For higher temperatures (up to 200°C), we offer high-temperature grades (e.g., N42SH, N38EH).
Q6: How do I determine the right arc magnet for my application?
A: Consider:
Size (OD/ID, thickness, arc angle)
Magnetic strength (grade)
Temperature resistance
Coating type

Q7: Are these magnets brittle? How should I handle them?
A: Yes, neodymium magnets are brittle. Avoid impacts, drilling, or sudden temperature changes. Use gloves for handling to prevent injuries from strong magnetic attraction.
Q8: Do you offer bulk/OEM discounts?
A: Yes! We provide volume pricing for large orders. Contact us with your quantity and specifications for a customized quote.
