Technical Specifications

Frequently Asked Questions

How strong is this N52 rod magnet?
This magnet can produce an estimated pull force of up to 17.5 lbs under ideal conditions. As a Grade N52 magnet, it is among the strongest commercially available, exceeding N50, N48, N45, and lower grades, offering excellent strength in compact applications.

What are the coating and durability features?
This magnet is coated with a durable triple-layer Nickel-Copper-Nickel finish, which provides excellent corrosion resistance and mechanical protection.

Is it safe to use around electronics and other devices?
While safe when used properly, neodymium magnets should always be kept away from pacemakers, magnetic media, and sensitive electronics due to their intense magnetic fields.

What is the maximum operating temperature?
This N52 magnet is rated for continuous use up to 80°C (176°F). Exceeding this temperature may cause a permanent reduction in magnetic strength.

Can I order in bulk?
Yes. For large quantity purchases, please contact us directly for wholesale pricing and availability.

Safety Note:

These magnets are extremely powerful and fragile. They can pinch fingers or break if allowed to collide. Always handle with care, keep out of reach of children, and avoid contact with pacemakers or sensitive electronics. Review safety guidelines before use.
