Made from strong magnetic elements to create some of the world's most powerful magnetic alloys, rare earth magnets are some of the mainstays of today's technology. They inherit their name from the days of the development of the periodic table, when the elements used to create these metals were considered to be rare and precious metals. Today, the metals used to create the magnets retain the name but not the quality, because the metals are actually found in abundance throughout the world. Rare earth magnets are used for many applications in today's society, from wind turbine generators to headphones to electric guitar pickups and so much more. To ensure that you are using the right magnets for the correct need, follow the standard grading system and be sure that you are treating them correctly.
The Rare Earth Magnets Grading System
Rare earth magnets are assigned certain letters of the alphabet based on how high of temperatures the magnet can withstand. Here is a basic rundown of the different grades.
*N Magnets-can withstand temperatures from 70-80 degrees Celsius or 158-176 degrees Fahrenheit
*M Magnets-can withstand temperatures up to 100 degrees Celsius or 212 degrees Fahrenheit
*H Magnets-can withstand temperatures up to 120 degrees Celsius or 248 degrees Fahrenheit
*SH Magnets-can withstand temperatures up to 150 degrees Celsius or 302 degrees Fahrenheit
*UH Magnets-can withstand temperatures up to 180 degrees Celsius or 356 degrees Fahrenheit
*EH Magnets-can withstand temperatures up to 200 degrees Celsius or 392 degrees Fahrenheit
It is important to remember that these temperatures should not be exceeded while working with your magnets. Overheating could damage their magnetic capabilities, and, in some cases, cause them to shatter or break more easily. If you need a magnet with a higher resistance, purchase one with a higher grade instead of using what you already have and damaging one or two. This will not only save you money, but will also help keep your magnets in top condition.
It is equally important to know your needs before you purchase. Remember that the higher the grade, the more brittle the magnet will be. This means that you will either need to be super-careful with the powerful magnets, or you need to find a way to protect them by finding a professional business that will coat or plate them for you.
Understanding the grading chart for rare earth magnets as well as understanding what you need will reap you many benefits in the long run. Be sure to educate yourself before purchasing so that you are fully aware of the exact magnets you need. By having all this information under your belt, you will be able to keep your magnets strong and useful for many years to come.
