1J22 alloy -iron cobalt soft magnetic alloy

1J22 alloy is high saturation magnetic induction strength iron cobalt vanadium soft magnetic alloy, in the existing soft magnetic material of the alloy saturated magnetic induction intensity was the highest (2.4t), Curie point is also very high (980 DEG C), the saturation magnetostriction coefficient maximum (60 to 100 * 10-6).

Due to high saturation magnetic induction strength, in the production of the same power of the motor, can greatly reduce the volume, when making an electromagnet, in the same cross-sectional area can produce a large suction force. Due to the high Curie point, so that the alloy can be in other soft magnetic material has been completely demagnetization under high temperature working, and keep the good magnetic stability. Due to the large magnetostrictive coefficient, which is very suitable for the magnetostrictive transducer, the output energy is high, and the work efficiency is also high. The low resistivity of the alloy (0.27 M /), it is not suitable for use in high frequency. The price is more expensive, easy to oxidation, processing performance is poor, add the appropriate amount of nickel or other elements, can improve its processing.

Process performance and requirements of 1J22 alloy
1.After 880 degrees Celsius, the alloy can be processed into thin strips and filaments, which can be punched, rolled or processed into various shapes of components.
2.hot rolled (forging) material, drawing wire and strip of this alloy can be cut and grinded. When the alloy is processed into a device, and after the slow cooling of the final heat treatment, the plastic is very poor, can only be slightly grinding.

Application of 1J22 alloy
With Stable performance and mature materials. It is suitable for light weight, small size of aviation, aerospace electrical components, such as the micro electronic rotor, the magnet pole, relays, transducers, etc..
