Annealed 1J79 Soft Magnetic Alloy Wire for Sensitive Magnetic Circuit Designs

Product Description

Overview
Annealed 1J79 magnetic alloy wire is specially processed for high sensitivity magnetic circuits that require optimal soft magnetic properties. It undergoes a strict hydrogen annealing process to enhance permeability and reduce internal stress, making it a go-to choice for highly sensitive or miniaturized devices.

Product Characteristics

• Fully annealed in hydrogen atmosphere

• Ultra-low coercivity

• Exceptional permeability uniformity

• Optimized for low residual magnetism

• Mirror-like surface for precision use

Application Scenarios

• Medical diagnostics equipment

• Magnetic amplifiers

• Navigation and positioning modules

• Smart energy sensors

• Precision electromagnetic control coils

Working Mechanism
The annealing process restructures the alloy’s crystalline lattice, relieving internal stress and improving domain wall movement. This results in higher μmax and stability across repeated magnetic cycling.

Specifications

• Optimized for low-noise, high-sensitivity devices

• Exceptional magnetic repeatability

• Reduced remanence and coercivity

• Supplied with certificate and MTC

• Long coil lengths with uniform quality

FAQ

Q1: Can the wire be used in cryogenic conditions?
Yes, 1J79 maintains stable properties at temperatures as low as -196°C.

Q2: What’s the standard annealing atmosphere?
Pure hydrogen, to prevent oxidation and maximize grain growth.

Q3: How is the wire stored or packaged?
In vacuum-sealed spools or moisture-proof reels, depending on customer requirements.
