1J30 Fe-Ni Soft Magnetic Alloy N30
1J30, also referred to as N30 alloy, is an iron-nickel soft magnetic alloy. It consists of approximately 30% nickel and 70% iron, with trace chromium and silicon additions. As a professional Chinese precision alloy supplier, ZYTC Alloy supplies high-quality 1J30 soft magnetic alloy bars, sheets, strips and custom machined parts with stable and consistent magnetic performance for global customers.
This alloy features high magnetic permeability and low saturation magnetic induction, coupled with outstanding magnetic characteristics and excellent machinability. 1J30 is characterized by a low Curie temperature ranging from 25¡æ to 200¡æ. Below its Curie temperature, the magnetic induction drops sharply and nearly linearly with rising temperature, making it ideal for temperature-sensitive magnetic compensation designs. Besides unique magnetic behavior, 1J30 alloy delivers good thermal stability and corrosion resistance, enabling long-term stable service under harsh working environments.

Key Features
- High magnetic permeability, low magnetic saturation induction
- Near-linear reduction of magnetic induction with temperature below Curie point (25~200¡æ)
- Low Curie temperature, perfect for magnetic shunt & temperature compensation
- Excellent machinability and forming performance
- Good thermal stability and corrosion resistance
- Reliable performance for long-term operation in tough environments
Process Performance
Solution treatment or aging after cold rolling can optimize mechanical properties and extend service life. Annealing / tempering after cold rolling reduces hardness and improves machinability. This process also expands the usable temperature range and enhances physical properties including low-temperature toughness and corrosion resistance.
Heat Treatment Property
1J30 Fe-Ni soft magnetic alloy possesses balanced mechanical and processing properties. It retains good strength and plasticity under high-temperature conditions.
Note: The room-temperature fatigue limit of 1J30 reaches 300~400 HRC. It features decent thermal strength and oxidation resistance.
