How to select the materials and grades of rare earth magnets?
When customers don’t know what magnet to use, we will provide suggestion. Our suggestion depends on application and specific size.
If you use magnet on room temperature, neodymium magnet is best. With small magnet size and low grade, it gets strongest power than other material.
The magnet size can be smaller compared with N35 magnet if you use N52 magnet.
If you need strong magnet with max working temp 300 centigrade, samarium cobalt magnet is the right choice.
When you use magnet on a car starting dynamo or similar structure, you have to use neodymium magnet in SH series or above.
Keep in mind that the higher the grade the more brittle the magnets will be while selecting a grade.
Make sure you will not reach or exceed the max value, or the magnets will be damaged while selecting a grade based on working temperature.
China Magnets Source Material has the ability to produce magnets in a variety of materials and grades that can be applied to all applications. Please feel free to contact us if you have any question for choosing a material or grade.
