Precision 1J79 Soft Magnetic Wire for Low-Frequency Electromagnetic Applications

Product Description

Introduction
1J79 soft magnetic wire is engineered for low-frequency electromagnetic applications where magnetic accuracy and response are critical. With its low coercivity and high magnetic permeability, this nickel-iron alloy wire ensures consistent signal response and reduced magnetic losses, especially under low-intensity AC fields.

Core Properties

• Nickel content around 79%

• Extremely low hysteresis loss

• Excellent magnetic linearity

• High maximum permeability at low field strength

• Smooth, burr-free finish for coil winding

Applications
1J79 wire is an ideal material for:

• Chokes and inductors

• Signal transformers

• Low-frequency oscillators

• Aerospace navigation sensors

• Electroacoustic devices

Working Principle
The wire magnetizes easily at low field strengths, thanks to minimal domain wall resistance and low retentivity. Its high nickel composition aligns the structure into a soft magnetic phase, allowing accurate and fast electromagnetic signal conversion in low-frequency ranges.

Technical Data

• Minimal energy loss in alternating magnetic fields

• Excellent ductility for micro winding

• Stable performance under low frequency (<100 kHz)

• Highly uniform magnetic behavior

• Can be annealed to customer specifications
