1. Are neodymium and rare earth magnets the same thing?
Neodymium magnets are the most commonly used type of rare earth magnets. Rare earth magnets are made from rare earth elements found on the periodic table. Neodymium magnets are the strongest rare earth magnets and the strongest magnets in the world.
2. What does the N35, N40, N42, N45, N48, N50, N52 grade mean?
Neodymium magnets are graded by the maximum strength they can be magnetized to. The higher the number the stronger the magnet is, however the higher the number the more brittle the magnet becomes as well.
3. Do neodymium magnets lose their strength over time?
Very little. Neodymium magnets are the most permanent magnets in the world. As long as you don’t over heat them they will lose less than 1% of their strength every 10 years. You will not even notice unless you measure it.
4. What is the Gauss of your magnets?
The gauss varies depending on the size of magnet. All our magnets have the gauss listed in the description box of each product.
5. Why are neodymium magnets coated?
Neodymium magnets are coated to prevent oxidation and rust. Neodymium magnets are made of neodymium, iron and boron. The iron will oxidize quickly and will rust over time, the coating protects the magnet from this.
Strong development capability of magnet with 3M glue, stainless steel hardware products, magnet with plastic products and other custom made magnet assembly.
