Permalloy iron-nickel alloy is a 79-80% nickel alloy, a high saturation magnetic induction soft magnetic alloy, with high initial permeability, maximum permeability and low coercivity.
The saturation magnetic induction intensity of 1J79 is greater than 0.75T. 1J79 alloy has good anti-rust performance and processing performance, and can be used to make components with extremely precise shapes and sizes.
Ni79Mo4 alloy is smelted in a vacuum induction furnace, and is made into cold-rolled strip, cold-drawn wire or hot-rolled (forged) plate and bar after hot and cold plastic deformation. In the aviation industry and other electronic industries, it is used to produce electronic components with high sensitivity, precise size, small size, low high-frequency loss, good time and temperature stability, and special functions.

- High frequency and low voltage transformer
- Leakage protection switch core
- Common mode inductor core
- Current transformer core
- Communication
- Instrumentation
- Electronic computer
- Telemetry
- Remote control
- Wireless charging and other systems
