1J36 Μαλακό κράμα σιδήρου με θερμομαγνητική σταθερότητα και χαμηλή οπισθέλκουσα για συστήματα ελέγχου ακριβείας

Engineered specifically for demanding industrial control instrumentation, aviation sensors, and harsh environment electromagnetic systems, our 1J36 Soft Magnetic Alloy Strip delivers ultra-stable magnetic permeability, optimized Curie temperature control, and exceptional dimensional stability under severe thermal and mechanical stresses.

1J36 is a specialized binary nickel-iron soft magnetic alloy containing approximately 36% nickel, engineered to provide high initial permeability, low coercive force, and precise thermal-magnetic stability across wide temperature fluctuations.

Manufactured through vacuum induction melting (VIM) followed by electroslag remelting (ESR) and multi-pass cold rolling, DLX 1J36 strip ensures ultra-low gas content, zero surface micro-cracks, and homogeneous grain orientation. It is the premier core material for electromagnetic actuators, flowmeter sensors, magnetic shielding cans, and harsh-environment telemetry switches requiring minimal hysteresis losses and zero drift.

• Minimal Thermal Drift: Maintains consistent magnetic induction and flux density across varying temperature regimes, avoiding sensor calibration errors in deep-well or subsea monitoring units.
• Low Core Losses: Ultra-clean internal grain structure reduces magnetic hysteresis loop area and minimizes heat generation during rapid switching cycles.

• Sub-Micron Thickness Consistency: Continuous thickness laser-gauging during cold rolling guarantees uniform electromagnetic response across the entire coil length.
• Zero Edge Burr & Micro-Crack Free: Advanced rotary slitting technology delivers clean edges ready for high-speed continuous progressive stamping dies.

• High Oxidation Resistance: Higher nickel content compared to standard silicon steels provides superior resistance against atmospheric moisture, industrial chemicals, and sulfur-free process gases.

• High-pressure magnetic flowmeters, logging-while-drilling (LWD) electromagnetic pickups, and cryogenic control valves.

• Gyroscope magnetic shields, cockpit sensor relays, high-reliability solenoid valves, and altitude telemetry components.

• Sensitive magnetic triggers, leakage protection switch cores, magnetic amplifier laminations, and current transformer shields.

• Dedicated 1,200 Tons/Month Production Capacity: Complete in-house metallurgical capability spanning VIM melting, ESR refining, precision hot/cold rolling, continuous hydrogen atmosphere annealing, and CNC slitting.
• 100% Full-Process Quality Assurance: Every batch undergoes chemical spectroscopy (OES), eddy current testing, tensile verification, dimensional laser inspection, and magnetic B-H loop curve certification.
• Custom OEM & Slitting Services: Tailored strip thicknesses, custom edge conditioning, protective interleaving, and vacuum-sealed desiccant packaging for international sea and air freight.
• Global B2B Supply Chain Support: Rapid turnaround on custom pilot runs, export documentation compliance, and dedicated metallurgical engineering support.

To achieve optimal magnetic permeability and relieve internal stresses induced by stamping or bending, 1J36 components should undergo protective atmosphere heat treatment. We recommend dry hydrogen or high-vacuum annealing at 1100°C−1150°C for 2−3 hours, followed by controlled furnace cooling down to 200°C.

While 1J50 (approx. 50% Ni) offers higher maximum permeability and saturation magnetic induction (Bs), 1J36 exhibits unique thermal expansion compatibility and stable magnetic response in specific temperature compensation and harsh environment control loops where 50% Ni alloys might suffer from higher thermal drift.

We offer flexible B2B minimum order quantities based on strip gauge and custom slitting requirements. Coils are securely packed with anti-corrosion VCI paper, desiccant pouches, protective plastic film, and heavy-duty ISPM-15 compliant export wooden crates to ensure zero rust during oceanic transit.

Yes. Our precision slitting lines can slit strip down to 5.0 mm width with slit width tolerances within ±0.05 mm, accompanied by deburred, rounded, or slit edges optimized to extend tool life in automated stamping presses.
