As an original manufacturer for high quality magnets, we are able to supply the rare earth Neodymium magnets in many different grades such as N35, N38, N40, N42, N45, N48, N50, N52...... Here are some frequently asked questions when you are thinking about how to choose the suitable magnets?
What are Magnet Grades?
The number comes from an actual material property, the Maximum Energy Product of the magnet material, expressed in MGOe (Mega Gauss Oersteds). It represents the strongest point on the magnet's Demagnetization Curve, or BH Curve.
For your information here are the materials grades which can produce for the Neodymium magnets.
A magnet grade is a good measure of the strength of a magnet. In general, the higher numbers indicate the stronger magnet.

How to measure the magnetic strength of a magnet?
Pull force is how much force you have to pull on a magnet to move it away from something, such as a steel surface or another magnet. The specific way the magnet is tested can have a great influence on the measured strength.
There are two common measures of a magnet's strength: the pull force and the strength of the magnetic field.
Pull force is how much force you have to pull on a magnet to move it away from something, such as a steel surface or another magnet. The specific way the magnet is tested can have a great influence on the measured strength.
It is a great reference for magnet strength, expressed as a single number. Even if your application doesn't pull on the magnet in the same way, this is often a good number to use to compare the strength of different magnets.
The Magnetic Field Strength is a measurement of the magnetic field's strength and direction at a particular point near the magnet. It is expressed in Gauss or Tesla. The magnetic field strength usually depends on the size, shape and grade of the magnet, where the measurement is performed, and the presence of any other magnets or ferromagnetic materials nearby.
What Grade Should I Choose?
If you need the magnet to be with the highest strength and to be used at the room temperature, the N52 grade is the strongest available.
If you need the magnet to be workable under high working temperatures, so you can choose our high temp magnets such as N35SH, N38SH, N40SH, N42SH, N45SH etc.
Hope these information will be helpful for you to choose the suitable magnets for your application!
It depends on the your application for the Neodymium magnets.
If you need the magnet to be with the highest strength and to be used at the room temperature, the N52 grade is the strongest available.
If you need the magnets to be used under the working temperature 60°C -80°C, you can choose the N series grades, such as N35, N38, N42, N45, N48, N50, N52.
If you need the magnet to be workable under high working temperatures, so you can choose our high temp magnets such as N35SH, N38SH, N40SH, N42SH, N45SH etc.
Hope these information will be helpful for you to choose the suitable magnets for your application!
