Custom service

Rare Earth Neodymium countersunk magnets are among the most powerful permanent magnets available. Our range is suited to a wide range of applications, including office and home.

Countersunk ndfeb magnet are extremely strong for their size. Shapes include rings, blocks, discs and custom. To prevent unwanted oxidation, neodymium magnets are usually finished with zinc, nickel or epoxy coating.

Note:

1. Keep away from pacemakers.

2. Powerful magnets can hurt your fingers.

3. Not for children, parental supervision required.

4. All magnets may chip and shatter, but if used correctly can last a lifetime.

5. If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage.

FAQ:

Q1. What are neodymium countersunk magnets?
A1. Neodymium countersunk magnets are powerful magnets that have a countersunk hole in the center, making them ideal for applications where the magnet needs to be securely attached to a surface.

Q2. What are the benefits of using neodymium countersunk magnets?
A2. Neodymium countersunk magnets are known for their strength, durability, and versatility. They have a strong magnetic pull, making them ideal for holding applications, and the countersunk hole allows them to be securely attached to a surface.

Q3. What are the drawbacks of using neodymium countersunk magnets?
A3. Neodymium countersunk magnets can be brittle and can break if dropped or exposed to strong impact. They also have a very strong magnetic field and should be handled with care.

Q4. What is the maximum operating temperature for neodymium countersunk magnets?
A4. The maximum operating temperature for neodymium countersunk magnets is around 80-200°C (176-392°F), depending on the specific grade of the magnet.

Q5. How can you increase the strength of a neodymium magnet?

A5. By exposing the weakened magnet to freezing temperatures, the molecules in the magnet will have less kinetic energy and will slow down. This decreased movement will allow the atoms to line up better creating a more concentrated magnetic field which will result in a stronger magnet.
