Ultra-High Saturation Induction 2.4T Iron Cobalt Magnetic Alloy Hiperco 50 Sheet with Superior Magnetostrictive Output and High Curie Point Thermal Stability

Engineered for high-power magnetostrictive transducer cores, aviation electrical machines, and sensitive electromagnetic actuators, our precision 1J22 (Hiperco 50) iron-cobalt soft magnetic sheets deliver ultra-high saturation induction (2.4T), superior magnetostrictive response, and tight thickness tolerances.

High-power ultrasonic cleaning equipment, sonar arrays, and precision micro-displacement actuators demand core materials capable of maximum electromechanical energy conversion under intense magnetic fields. Precision iron cobalt magnetic alloy 1J22 Hiperco 50 sheet fulfills these critical engineering requirements by combining approximately 50% cobalt with high-purity iron and vanadium grain refinement, ensuring superior magnetostrictive strain (λs ≈ 60–80×10⁻⁶) and high magnetic saturation induction.

Manufactured through advanced vacuum induction melting (VIM), electroslag remelting (ESR), and multi-roll precision cold rolling, our precision iron cobalt magnetic alloy 1J22 Hiperco 50 sheet features ultra-clean grain boundaries, minimal non-metallic inclusions, and uniform crystallographic texture. Tight thickness tolerances and stress-controlled slitting guarantee zero micro-cracking and high dimensional accuracy during precision stamping, laser cutting, and laminated core stacking.

With a saturation flux density reaching 2.4 Tesla—the highest among all commercial soft magnetic alloys—this material allows engineering teams to reduce core volume and overall weight by up to 30% compared to traditional silicon steel or nickel-iron permalloy in aircraft generators, compact motors, and high-flux transformer assemblies.

Possessing an exceptionally strong positive saturation magnetostriction coefficient, precision 1J22 Hiperco 50 sheet produces powerful mechanical elongation when magnetized. This high electromechanical coupling factor ensures maximum acoustic energy radiation and high acoustic output efficiency in underwater sonar transmitters and industrial ultrasonic transducers.

Featuring a Curie temperature exceeding 930°C, 1J22 alloy preserves high magnetic flux capacity and stable permeability even under severe elevated-temperature working environments, preventing output degradation or magnetic thermal drift in aerospace propulsion systems.

Refined vanadium addition and controlled cold-reduction schedules optimize magnetic domain wall mobility and restrain grain coarsening during final magnetic heat treatment. This metallurgical control significantly lowers hysteresis loss and minimizes eddy current heating in medium-to-high frequency alternating field operations.

Serves as the vital magnetostrictive driving element in high-intensity ultrasonic welders, industrial cleaning transducers, sonar transmitters, acoustic echo sounders, and precision micro-positioning actuators.

Applied in high-power-density aircraft starter-generators, auxiliary power units (APU), radar magnetic components, and specialty lightweight electric motor stators and rotors.

Utilized in fast-acting magnetic valves, common-rail diesel injector actuators, precision optical shutter drives, and beam-steering electromagnetic deflection systems requiring millisecond-level response.

Engineered for ultra-high magnetic field shielding boxes, medical magnetic resonance focusing pole pieces, and particle accelerator beam guidance components where standard shielding alloys easily reach saturation.

DLX operates an end-to-end metallurgical production chain covering Vacuum Induction Melting (VIM), Electroslag Remelting (ESR), precision multi-roll cold rolling, and automated tension leveling. This comprehensive processing ensures ultra-low interstitial gas levels (C, S, P <= 0.02%), exceptional melt purity, and strict chemical uniformity across every batch.

Equipped with high-precision CNC slitting and progressive stamping facilities, DLX delivers continuous cold-rolled strips, custom stamped lamination profiles, and high-temperature inter-laminar oxide/inorganic insulation coatings customized to CAD drawings for immediate core assembly.

With a unified production capacity of 1,200 tons per month across specialized high-temperature and precision soft magnetic alloy lines, DLX supports flexible minimum order quantities for pilot prototyping as well as stable volume delivery for global tier-one electronics and aerospace suppliers.

Every production lot undergoes rigorous inspection for chemical composition via direct-reading spectrometry, dimensional micro-tolerances via laser gauges, and magnetic parameters (Bs, Hc, μm) using closed-circuit hysteresis graph testing. We provide detailed magnetic heat treatment profiles (dry hydrogen/vacuum protocols) to ensure clients achieve optimal target properties.

Cold-rolled 1J22 sheet possesses high internal lattice strain and high hardness, resulting in low initial permeability and elevated coercive force. Final annealing in a dry hydrogen or high-vacuum environment at 820°C–860°C relieves cold-working stress, promotes controlled grain growth, and achieves the atomic ordering balance required to minimize coercive force (Hc) and unlock full 2.4T saturation induction.

While 1J79 (80% Ni Permalloy) offers higher initial permeability at extremely weak magnetic fields, its saturation induction is limited to approximately 0.75T–0.80T. 1J22 provides three times the flux capacity (2.4T) and much higher magnetostrictive strain, making it the only viable choice for high-power-density cores, compact stators, and active transducer drivers.

Through multi-roller precision cold rolling and automated continuous gauge inspection, DLX maintains thickness tolerances within +/- 0.003mm to +/- 0.005mm on thin gauges (0.05mm to 0.50mm), guaranteeing consistent core stacking factors and uniform flux distribution in laminated stacks.

Yes. DLX provides precision custom laser cutting, micro-stamping, and deburring services based on customer CAD/technical drawings, including surface oxidation or specialized inorganic insulation coatings capable of withstanding subsequent magnetic annealing temperatures.

Slit strips and sheets are treated with neutral rust-inhibiting agents, interleaved with protective paper, vacuum-sealed with moisture-absorbing desiccant in heavy-duty foil barrier bags, and packed into reinforced export-grade plywood crates to prevent transit vibration, physical distortion, and moisture exposure.
