High working temperature rod Neodymium magnets

Horizon supply Neodymium magnets in round shaped.

Usually we call them cylinder Neodymium magnets, disc Neodymium magnets or rod Neodymium magnets.

Neodymium magnets known as NdFeB, Neodymium-Iron-Boron, Neo, NIB or Rare Earth Neodymium magnets, are the third generation of rare earth permanent magnets.

They offer the highest energy product of any material today and are available in a very wide range of shapes, sizes and grades.

These qualities have made NdFeB magnets preferable over the commonly used larger and less powerful Ferrite magnets.

Although the Curie temperature for NdFeB materials is 310-370ºC, some irreversible loss of output may be expected at even moderate temperatures.

NdFeB magnets also have a moderately high reversible temperature coefficient of Br which reduces total magnetic output as temperature rises.

Selection of NdFeB instead of SmCo, for example, is a function of the maximum temperature of the application, required magnetic output at typical use temperature and total cost of the system.

However, they are sensitive to oxidization and can develop corrosion, so they require surface protection like phosphate, passivation, Ni, NiCuNi, Zn, Epoxy, NiCuNi+Sn or others.

sensors rod Neodymium magnets Characteristics:

Genuine Neodymium magnet, without La (Lanthanum) or Ce (Cerium) to destroy magnet quality

Outstanding magnetic properties – Br high to 14.5 kGs (1 - 45T) and (BH)max high to 52 MGOe (414 kJ/m3)

High demagnetization resistance –maximum Hcj higher than 35 kOe (2785 kA/m)

High working temperature – maximum working temperature high to 230ºC

Wide range of grades with new ones regularly being developed – High magnetic properties, AH grades or Low Weight Loss materials and so on.

Size:

Normal Size Range: D (Diameter): 1~180mm, T (Thickness): 0.4~150mm

Maximum Size: D180 x T60mm, D80 x T150mm

Minimum Size: D1 x T0.4mm

Orientation Direction Size: Lower than 80mm

Tolerance: Generally +/-0.1mm, Particularly +/-0.03mm

Cylinder Neodymium Magnet Machining Method:

Generally the small axially oriented cylinder (D10mm) can be pressed to shape and then grinded and sliced.

But sometimes the big axially oriented cylinder should be core-drilled or EDM cut from a block, so as to ensure the magnetic properties especially for high end grades or shorten the lead time.

Prior to coating, the small cylinder needs vibration tumbling and the big cylinder needs manual chamfering.

Main Application:

High speed electric motors, sensors, magnetic sputtering cathodes, magnetic assemblies, holding applications, etc.

Main Test Items Prior to Delivery:

In order to ensure NdFeB magnets to meet requirements, we main test following items: size, weight loss, magnetic properties, flux, flux density, angle deviation, magnetic loss, appearance, coating thickness, corrosion resistance, etc.
