NiFe Alloy 1J30

Short Introduction:

  • NiFe Alloy 1J30 is suitable for traveling wave tube, magnetron, voltage regulator, odometer, wind anemometer and meter magnetic shunt compensation components.


    NiFe Alloy 1J30

    1J30 alloy is an iron-nickel alloy, also known as N30 alloy. It is composed of about 30% nickel and about 70% iron with small amounts of chromium and silicon. It is a magnetic material with high magnetic permeability and low magnetic saturation, as well as excellent magnetic properties and good processing properties.

    Process performance:

    Solution treatment or aging treatment after cold rolling can improve its mechanical properties and service life. Annealing or tempering after cold rolling can improve the machinability and reduce the hardness, thereby improving its operating temperature range and physical indicators such as low-temperature toughness and corrosion resistance.

    Heat treatment:

    NiFe Alloy 1J30 stainless steel has good comprehensive mechanical properties and process performance. 1 J 30 can maintain high strength and plasticity at high temperatures. The room temperature fatigue limit of 1 J 30 can reach 300~400 HRC. It has thermal strength and oxidation resistance. Good, 1 J 31 has high creep strength and durable plasticity below 800°C, and can still maintain certain plasticity and toughness at 250°C. 2 1 J 31 has good corrosion resistance and weldability. 3 1 J 31 The thermal expansion coefficient is small.

    Features: Below the Curie temperature, its magnetic induction intensity decreases sharply and approximately linearly as the temperature increases.

    1J30 alloy is mainly used to manufacture electromagnetic components, such as inductors, sensors, transformers, etc. Due to its high magnetic permeability and low magnetic saturation, the efficiency and performance of electromagnetic components can be greatly improved. At the same time, 1J30 alloy has high thermal stability and corrosion resistance, and can operate stably for a long time in harsh environments.
