1j22 Nickel-Iron Soft Magnetic Alloy Wire is high saturation magnetic induction intensity of iron, cobalt, vanadium soft magnetic alloy in existing soft magnetic alloy calcium alloy has the highest saturated magnetic induction intensity (2.4 T), and high Curie temperature (980 ºC), saturation magnetostriction coefficient of maximum (60 ~ 100 * 10-6).Due to the high saturation magnetic induction intensity, when making an equal power of motor, can greatly reduce the volume, when making electromagnet, under the same cross-sectional area can produce larger suction force.Due to their high Curie point, can make the alloy can be in other soft magnetic alloy material has been completely demagnetization work under the high temperature, and maintain good magnetic stability.
Application: suitable for making quality is light, small volume of aviation and space flight with electrical components, such as, micro-motor rotor magnet pole head, relays, transducers, etc

Nickel-Iron Soft Magnetic Alloy Wire Picture:
.Due to the large magnetostrictive coefficient, and is suitable for used as a magnetostrictive transducer, output energy is high, the efficiency is high.The resistivity of low alloy (0.27 mu Ω m.), is not suitable for use under high frequency.Price is more expensive, easily oxidized, processing performance is poor, adding suitable nickel or other elements, can improve the processing performance.
