Rare earth magnets are generally made from alloys or other materials. They are the strongest permanent magnet among the same kind. One good thing about using rare earth super magnet is that their crystalline structures feature very high anusotroph, which indicates that a crystal of the material is located at the very east of magnetic field in one particular direction while resisting being magnetized in any other direction. Here, we present the SmCo type, a type of rare earth magnets that performs in good condition in low temperature. This type of magnet possesses strong magnetic and coercive force, high resistance to corrosion and high working temperature (350 degree centigrade).

This product we are going to introduce to you is an efficient permanent magnet made of samarium, cobalt and other elements of rare earth magnets. SmCo magnet is widely used in manufacturing headphone, speaker, watch, transducers, motors, generator and radar, etc. If you are looking for optimum permanent magnets, Micromeg Technology is your best choice. Please do not hesitate to send inquiry for more info. We are confident to serve you with our best.
