Products Description
Neodymium rare earth disc magnets are a type of rare earth magnet known for their strong magnetic properties. They are composed of neodymium, iron, and boron-hence the chemical formula NdFeB. These magnets are renowned for their exceptional strength, which is several times greater than that of traditional ferrite magnets.
Features of neodymium rare earth disc magnets
Strength: They are some of the strongest permanent magnets available in terms of magnetic strength per mass or volume.
Size and Shape: Disc-shaped neodymium magnets come in a variety of sizes, from very small to quite large, and their dimensions can be tailored to meet specific requirements.
Temperature Sensitivity: Neodymium magnets lose their strength at higher temperatures, and their maximum operating temperatures are usually lower compared to other magnet materials.
Corrosion Resistance: They can be susceptible to corrosion, so they are often coated with nickel, zinc, or other materials to protect them from environmental factors.
Hardness: Neodymium magnets are very hard and brittle, which means they can be easily chipped or broken if dropped or if they collide with another magnet.
Applications of Neodymium rare earth disc magnets
1.Electronics: Used in speakers, headphones, and microphones for sound reproduction.
2.Motors and Generators: Found in electric vehicles, wind turbines, and other types of motors and generators for energy conversion.
3.Industrial: Utilized in various industrial applications, such as robotics, forklifts, and lifting systems.
4.Consumer Products: Common in household items like magnetic hooks, door latches, and separators.
5.Medical Devices: Employed in medical equipment like magnetic resonance imaging (MRI) machines.
