High Flux 1J22 Soft Magnetic Alloy and Hiperco 50 Strip with Ultra-Thin 0.05mm Gauge for High-Power Magnetic Devices

DLX Alloy delivers high-purity 1J22 (Hiperco 50 equivalent) precision soft magnetic alloy strip, cold-rolled to ultra-thin gauges (down to 0.05 mm) with strict dimensional tolerances and tailored magnetic permeability. Engineered with ~49-51% Cobalt, 1.5-2.0% Vanadium, and high-purity Iron, this Iron-Cobalt-Vanadium (Fe-Co-V) alloy delivers an unmatched saturation magnetic induction (Bs≥2.4 T), making it the premier core material for high-power magnetic devices, aerospace stators, and high-frequency transformers where compact footprint and maximum flux density are essential.

Engineered for next-generation electromagnetic actuators, high-density rotating machines, and aviation-grade pulse generators, our 1J22 (Hiperco 50) soft magnetic strip offers the highest saturation magnetization among commercially available soft magnetic alloys.

Through precision Vacuum Induction Melting (VIM) and multi-pass cold rolling under controlled tension, DLX ensures homogeneous metallurgical structure, ultra-low carbon content, and minimal non-metallic inclusions. When properly final-annealed in a dry hydrogen atmosphere, the material exhibits optimized magnetic domains, low coercive force, high Curie temperature, and low core loss under alternating magnetic fields.

• Maximum Saturation Flux Density: Delivers up to 2.4 Tesla saturation induction, allowing a 30% to 50% weight and volume reduction in electromagnetic cores compared with silicon steel or permalloy.
• High Curie Temperature Operating Window: Maintains stable ferromagnetic characteristics and magnetic permeability at high ambient temperatures exceeding 400°C to 500°C without irreversible flux degradation.
• Ultra-Fine Dimensional Tolerance: Cold-rolled on high-precision Sendzimir mills with automated gauge control (AGC), achieving tight thickness tolerances and low edge-camber for uniform core stacking.
• Customized Heat-Treatment Response: Optimized vanadium balance enhances cold-workability and ductility while providing predictable grain growth during final dry hydrogen magnetic annealing.

• Aviation & Defense Power Systems: High-torque density starter-generators, airborne APUs, and servo motor laminations.
• Electromagnetic Actuators & Relays: Fast-response magnetic valves, magnetic bearings, and ultra-high magnetic field poles.
• Medical Imaging & Optical Scanners: Deflection yokes, beam-focusing pole pieces, and magnetic flux concentrators.
• Precision Laminated Cores: High-frequency pulse transformers, inductors, and specialized sensor cores.

• Integrated Full-Chain Production: Complete in-house processing from vacuum melting, electroslag remelting (ESR), hot forging, precision cold rolling, to bright continuous annealing.
• Stringent Quality & Traceability: 100% heat-lot traceability with full spectroscopic chemical verification, eddy-current surface inspection, and magnetic property testing reports.
• Robust Monthly Capacity: Over 1,200 tons/month total precision alloy production capacity, ensuring short lead times and flexible volume scaling.
• Tailored B2B Customization: Customizable supply formats (slitted coils, straight precision-cut strips, custom hardness tempers, and batch-matched pilot trial lots).

1J22 (Fe-Co-V alloy) provides the highest saturation magnetic induction (Bs≈2.4 T), making it ideal for systems requiring maximum magnetic force within constrained volume/weight limits. In contrast, 1J50 and 1J79 (Fe-Ni alloys) provide higher initial and maximum permeability with lower coercive force, but saturate at much lower magnetic fields (0.75−1.55 T).

Yes. 1J22 strip is supplied in a cold-worked or lightly annealed state to facilitate stamping, laser cutting, or winding. To achieve peak magnetic properties (Bs≥2.35 T and minimum Hc), the finished parts must undergo high-temperature final annealing in a pure dry hydrogen atmosphere (dew point ≤−50°C) at 820°C - 860°C, followed by controlled cooling.

We provide strip slitting widths from 3.0 mm to 350 mm with slitting width tolerances controlled within ±0.05 mm. Strips are packaged with anti-rust vapor corrosion inhibitor (VCI) paper, sealed inside moisture-barrier bags, and secured in export-grade fumigated wooden crates on pallets.
