Product Description
Ring Neodymium Magnet
Ring Neodymium Magnet Factory
Neodymium bar magnets
Genuine Neodymium magnet
Horizon supply Neodymium magnets in ring shaped. The ring 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 ******0ºC,
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 *4.5 kGs (1. *5T) and
(BH)max high to *2 MGOe (**4 kJ/m3)
High demagnetization resistance maximum Hcj higher than *5 kOe
(***5 kA/m)
High working temperature maximum working temperature high to
**0ºC
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 (Outer Diameter): 1.5~**0mm, d (Inner
Diameter): 0.4~**0mm, T (Thickness): 0.4~**0mm
Maximum Size: D**0 x d**0mm x T*0mm, D*0 x d*0 x T**0mm
Minimum Size: D1.5 x d0.4 x T0.4mm
Orientation Direction Size: Lower than *0mm
Tolerance: Generally +/*0.1mm, Particularly +/*0.*5mm
Machining Method:
The machining method for the outer diameter is same as that of the
cylinder. And then it goes to inner diameter drilling and then
slicing. Prior to coating, the small ring needs vibration tumbling
and the big ring needs manual chamfering.
High demagnetization resistance Neodymium magnet Main
Application:
Electric motors, sensors, speakers, 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.
