Frequently Asked Questions

What are permanent cylindrical neodymium magnets?
They are high-strength permanent magnets made from an alloy of neodymium, iron, and boron (NdFeB), shaped into cylinders for various industrial uses requiring strong magnetic fields.
How long do permanent neodymium magnets last?
Neodymium magnets are highly stable and lose less than 1% of their magnetic strength over ten years if maintained within their specified operating temperatures and kept free from physical damage and corrosion.
Why do cylindrical neodymium magnets require surface treatment?
Neodymium magnets contain iron, which makes them susceptible to oxidation and corrosion. Surface coatings like nickel, copper-nickel, or epoxy are applied to protect them from environmental humidity and rust.
Can these magnets withstand high temperatures?
Standard neodymium magnets work best under 80°C (176°F). Exceeding their maximum operating temperature can lead to permanent loss of magnetization. Always select the appropriate grade if your application involves high-heat environments.
Are custom sizes available for cylindrical neodymium magnets?
Yes, they can be customized in terms of height, diameter, magnetization direction (axial or radial), and plating to fit the precise engineering requirements of your application.
