Isotropic SmFeN bonded magnets (NITROQUENCH-P)

Feature of NITROQUENCH-P

Material Powder

Provided by Daido Special Steel original manufacturing.

The highest magnetic property in isotropic bonded magnet

Exeeding NdFeB bonded magnet, (BH)max 98～112 kJ/m³

Excellent corrosion resistance

Possible to use without coating according to circumstances.

Execellent heat resistance

Thermal coefficient of emanance -0.05 %/deg C～-0.07 %/deg C ( -20～+120 deg.C.)

Long stable heat resistance

Longer stable heat resistance compared to NdFeB bonded magnet

Magnetization easiness

Saturation magnetizing field is 2400 kA/m (30 kOe), needs much higher magnetic field than NEOQUENCH-P.
In case of multipole magnetization when it cannot be raised input voltage, please let us support on the magnetization.

Application of NITROQUENCH-P

NITROQUENCH-P is isotropic magnet, different from anisotropic magnet which needs to be pressed in magnetic field. Since there is no magnetic field in the process, it is easier to measure to magnetic dust contamination.
This mganet is multiused with the cost performance, such as perosnal computer, cell phone, and various sensor.

Manufacturing process NITROQUENCH-P

There are 2 methods forming of NITROQUENCH-P, Injection mold and compression.

Injection mold

The injection molded is made from the compound that mixed Nd magnet powder and high end resin. Wide range of characteristic is covered as an isotropic bonded magnet including heat resistant and higher performance. Injection mold has flexibility of shape design and simultaneous mold with other part or different materials injections are possible, thus meets various kinds of needs from the customer. 2 shots technology contribute manufacturing cost saving through skipping process bonding a part with the other by the simaltaneous injection mold, improving concentricity quality at the same time.

Feature of injection mold magnet

1. Injection molded magnet has high level of charcteristic as isotropic bonded magnet.
2. Since this is isotropic manget, magnetization direction is free to choose, and advantageous for the multipole magnetization.
3. Injection molding shows better dimensional accuracy and excellent serial productivity.
4. Thin wall thickness minimum 0.3 mm, complicated shape can be produced. *1
5. The metal part such as backyoke, hub, shaft or other resin part can be produced with this simultaneous injection mold method.
6. Since the resin wraps the manget powder, it is rust proof and can be used by no coating. *2

• 1   There is some case that manufacturing the thickness 0.3 mm could be difficult because of design, please consult with sales staff.
• 2   When the coating is necessary by use condition, appropriate coating for the injection mold is prepared. Please consult with sales staff.

2 Shots technology

2 Shots technology is the method of simultaneous injection molding magnetic powder & resin material together.

Feature of 2 shots injection molding

• Skipping bonding and assembling process
• Improving concentricity
• Decreasing manufacturing cost

Compression magnet

Compression product is made from mixing magnetic powder with resin binder and reaches higher level of performance than injection mold product's.

Feature of compression product

1. As isotropic bonded manget, the highest level of magnetic performance
2. Since this is isotropic manget, magnetization direction is free to choose, and advantageous for the multipole magnetization.
3. Wall thickness ( Minimum 0.3 mm ) is available to produce. *1
4. An excellent anti-rust performance is realized by the Daido original coating technology.

1   Up to the shape 0.3 mm thickness might be difficult. Please consult with sales staff.
