Product Description

Permanent neodymium magnet countersunk hole ring magnet with screw


What are neodymium magnets?


Neodymium magnets are made from neodymium (Nd), iron (Fe) and boron (B) and are the strongest magnets that currently exist. The energy product of neodymium magnets is eight times stronger than that of anisotropic ferrite magnets and they have excellent mechanical strength. Since they rust easily, they are normally surface treated with nickel plating. The disadvantages of neodymium magnets are that they sensitive to heat and require careful handling. They are used widely for industrial products and in daily items such as clothing and household products. Our customers range from those who want to buy a small but strong magnet to companies making magnetic products.


It has many advantages like high coercive force, high energy, high performance/ cost ratio and can be easily formed into various shapes and widely used in many fields such as aviation, electronics, instruments, meters, DC motors, Liner motors, MRI, medical and health products. It is the third generation of rare earth permanent magnet and at the same time the most powerful and advanced commercialized permanent magnet today.
