Compact and strong rod magnet of neodymium in high grade of magnetisation (N42), an elegant pin board magnet, easy to grasp. Also suitable to create impressive compact Platonic solids. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnet.
Warning: Super Strong Rod Magnet NdFeB Not suitable for children under three years due to small parts. Magnets are no toys. Inappropriate use might cause injuries.
As the world invents and develops, we humans are continuously being introduced to new materials and methods for improving our living standards and making life easy. Leaps in the magnets industry is yet another area of development and focus. Neodymium is basically a rare Earth element which is mixed up with other important elements such as iron and boron to produce the world’s strongest permanent magnets. These permanent magnets are infamously known as neodymium magnets as well as neo, NIB, NdFeb and super magnets commonly. The extreme strength threshold of these magnets can be understood from the fact that even a small mass has the ability to easily support a load a thousand times its own weight. Due to the easily available raw materials along with the affordable price and remarkable product performance, neodymium magnets of all shapes and sizes are mass produced and are readily available for numerous applications in electronics, jewelry, toys and various industrial equipment.
We have developed new magnet for high temperature application ! Copper Coating Magnet
Neodymium magnet is with much higher Br than any other magnets such as AlNiCo, Sm-Co etc, but it also has a disadvantage, that its maximum working temperature and temperature stability are much worse than other magnetic materials, which directly restrict the wide application of Neodymium magnet in some special fields.
Usually, the temperature coefficient βHcj of Neodymium magnet is over -0.7%/℃, now we can supply new magnet less than -0.4%℃, this helps neodymium magnet with excellent temperature stability. Reversible temperature coefficient of Remanence( αBr) and Reversible temperature coefficient of Hcj is relative to ratio of length, square, length/thickness diagram( BH CURVE) etc.
If you need high temperature magnet for some special applications, we are ready to support you, also will be your best choice.
