This rod is identical in length and diameter and therefore a rod as well as a disc. Strong and handy, compact and elegant, suitable as pin board magnet even for glass boards and areas of magnetic paint. Also an ideal magnet for countersinking in wood or any other material. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnets.
NdFeB Rod Strong Rare Earth Magnet – The cylindrical shape allows smaller mechanical tolerance compared to segment magnets.
Motor assembly is made much easier; installation of one or more rings versus gluing arcs into place.
Currently attainable qualities: 35H, 40H, 45H, 38M, 35SH, 38SH, 42SH, 35UH, 40UH.
Rare Earth Craft Magnet sintering may prevent so-called weak spots.
Homogeneous flux of the poles.
Uniformity of the magnetic field is significantly better than that of segment magnets.
Magnets are multi-poled – thus the ring does not compromise the magnetic properties.
Ring magnets offer substantial cost savings on assembling the rotor.
No additional rings or protecting cases are required for fixation.
Different types of magnetization are possible: diametrical, multipolar as well asso called “skewed” magnetization.
This ring provides high cost-effectiveness as well as better motor performance (as compared to the usual segment magnets).
The radial orientation results in a super strong magnet by virtue of superior metallurgy developed specifically to BE radially oriented.
Impressive Strong Rare Earth Magnet, sticks a whole calender to a refridgerator or heavier objects to pin boards. Also suitable for research and science duties. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnets.
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.
