Premium Soft Magnetic Alloy 1J30 Wire For Precision Magnetic Circuit Components

Engineered for critical temperature-dependent magnetic circuits, our 1J30 Soft Magnetic Alloy Wire offers reliable, linear thermomagnetic compensation across designated operating ranges. Manufactured under proprietary vacuum induction melting and ultra-precision cold-drawing processes, DLX delivers consistent Curie point stability and exceptional electromagnetic permeability for mission-critical sensor and instrumentation applications.

1J30 is a specialized nickel-iron based thermomagnetic compensation alloy characterized by a pronounced, controlled change in magnetic induction within standard working temperature windows. By shunting excess magnetic flux as ambient temperature shifts, 1J30 wire actively counteracts thermal drift in permanent magnet systems, voltage regulators, electric meters, and precision aerospace sensors.

• Controlled Curie Temperature: Strict metallurgical control ensures accurate magnetic transition points tailored to your specific circuit requirements.
• High Electromagnetic Uniformity: State-of-the-art continuous hydrogen-atmosphere annealing yields superior batch-to-batch consistency and low core loss.
• Ultra-Fine Dimensional Tolerance: Advanced multi-die diamond drawing achieves microscopic diameter precision down to ultra-fine wire gauges.
• Custom Mechanical Properties: Available in fully annealed soft condition (M state) or customized spring-temper/semi-hard conditions for specialized coiling and assembly.

1. Linear Magnetic Permeability Response: Predictable drop in magnetic permeability across temperature increases allows exact system calibration.
2. Superior Chemical Purity: Vacuum induction melting (VIM) and electroslag refining minimize non-metallic inclusions, preventing localized flux saturation.
3. Pliable & Ductile Formability: Annealed wire exhibits excellent elongation and tensile properties, suitable for high-density coiling without surface cracking.
4. Stable Long-Term Performance: Resistant to structural aging and permanent magnetic degradation over millions of thermal cycles.
