Neodymium Permanent Magnet Price
1) High and stable Performance
2) Excellent anti-corrosion property
3) Perfect Consistence
The third generation permanent magnet in lanthanide series
Currently the most powerful permanent magnet
Excellent demagnetization effect
Surface coating to prevent Oxidization. Normally we can provide nickel, zinc, tin and epoxy coating. In the meantime we can also coating the magnet according to customer requirement.
Our magnet are widely used in aerospace machinery, electronic, medical, electronic acoustic, mechanical and electrical and instrumentation field.
Most frequent applications of sintered NdFeB magnets rod magnet neodymium rod are:
Electroacoustics: Loudspeaker, headphone, microphones
Engines & generators: Stepping motors, servo actuators & DC machines
Hard Disk Drive assemblies
Sensor technology, measuring technique
Impressive rod 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.
