Magnetic material at home and abroadDesignated suppliers of famous enterprises both at home and abroad

It has extremely high dimensional precision and magnetic uniformity.

It can be made into complex shapes that are difficult to realize by machining, and it is easy to integrate with other parts.

There are many characteristics such as the variety of magnetic charging method, low eddy current loss and corrosion resistance

The magnetic properties of ndfeb are as follows

Br: 3000 ~ 8000 gs

Hci: 4000-16000 Oe

BHmax: 2.5-11.5 MGOe

Commonly used surface treatment is electrophoresis epoxy, color is black grey

Salt spray test 72 Hours or more, and the maximum working temperature of 150-180 ℃

In order to achieve good, uniform mechanical and magnetic energy, the maximum size of the forming height is 50mm, and the wall thickness is 0.35mm

The inner diameter tolerance can be + / -0.05 mm or less.

Product performance:

It is isotropic to bond with the nd-b, which does not require the magnetic field orientation of the magnet in the pressing process.

In each isotropic magnet, it is found that the magnetic property of ndfeb is the highest.

Product application:

It is mainly used in various micro motors, such as spindle motor, stepper motor, synchronous motor, dc motor, brushless dc motor.

It can be used to replace the magnetic and ferrite magnets of nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-nd-n

The magnets can be coated with cathodic electrophoresis, Parylene coating and sprayed epoxy coating.

The coating effect is smooth and dense, with good anti-rust effect and anti-shedding property. According to the customer's needs, the magnetic body is radiated in a radial multipole, planar multipole and radial direction magnetization.

Fill in plastic inserts and metal inserts for customers

Product features:

It is usually made from the mixture of ndfe-boron alloyed powder and epoxy resin. It can also be mixed with plastic by injection or extrusion. It has the following characteristics:

1. Magnetic energy can be high: magnetic can be in between sintered nd-nd-ferroboron magnet and ferrite magnet, which is better in consistency and stability.

2. High precision and freedom of shape: the shape and size of the product are determined by the mold. It can be shaped like ring, tile, block, etc., without sintering and post-machining.

3. Good corrosion resistance: after electrophoresis coating or some special treatment, it can be used in daily or harsh environment.

4. Diversification of the magnetization method: the magnetic pole can be charged as multi-pole and oblique pole, and the waveform can be square wave and sine wave.

5. Suitable for large quantity and high production efficiency.
