Product Description
ccording the max working temperature, we can divide Sintered magnet to 7 grades, N grade is for 80 ℃,grade M is for 100℃,grade H is for 120℃,grade SH is for 120℃,grade UH is for 150℃ and grade EH is for 200℃,you according your demand to choose the grade which you need.
The main physical properties of sintered NdFeB
Our products
Mostly of rare earth permanent magnet always work do not at room temperature or under vacuum, in order to keep the accuracy of shape size and avoid the Corrosion and oxidation, we must make the coating on the surface.
Sometime, the customers have high demand of NdFeB anti-corrosion, antioxidant, we can design the magnet,add some elements, such as: niobium, vanadium, cobalt and other metal to replace part of the iron to catch the customer requirements of the acid and alkali resistant,antioxidant level, however, because of special material, we need MOQ for it.

Our products
The application of ndfeb magnet with fillister, we are easy to only pay attention to the magnetic properties of materials, the stability of its great importance is not enough, the stability of the material used, including stability, temperature stability, externalmagnetic field under the action of stability, and ironmagnetic material exposure to the role of stability, stability under mechanical action, the stability of the-ray irradiation, chemical stability and so on.
So when you choose the magnet, pls consider more.
