magnetic assemblies bread shaped Neodymium Magnet

Horizon supply Neodymium magnets in loaf or bread shaped. The loaf magnets are always used in industrial markets.

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.

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: L (Length): 1~180mm, W (Width): 3~180mm, H (Height): 1.5~100mm

Electric motors bread shaped Neodymium Magnet  Maximum Size: L50 x W180 xH80mm, L180 x W80 xH50mm,

Minimum Size: L1x W3 x H2mm

Orientation Direction Size: Lower than 80mm

Tolerance: Generally +/-0.1mm, Particularly +/-0.05mm.

Machining Method:

Generally the loaf requires only EDM cutting from the big block. Sometimes, for large quantity, it can be sliced from a big block to many small blocks, and then the small blocks need processing with a shaped diamond grinding wheel which provides the precise dimensions and speeds up the machining process. Prior to coating, the small loaf needs vibration tumbling and the big loaf needs manual chamfering.

Loaf Neodymium Magnet  Main Application:

Electric motors, wind turbines, pump couplings, chemical pumps, magnetic assemblies, 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.
