1J36 Soft Magnetic Alloy Strip (UNS K93600) : High Initial Permeability and Near‑Zero Thermal Expansion
1J36 Soft Magnetic Alloy Strip represents the pinnacle of low‑carbon nickel‑iron precision materials, delivering unparalleled magnetic performance and dimensional stability for critical electromagnetic applications. Engineered with 36 wt % nickel content and a balance of iron, this strip exhibits high initial permeability, low coercivity, and minimal hysteresis loss under alternating magnetic fields. Its exceptional resistance to corrosion in humid, saline, and hydrazine environments ensures reliable operation in South Asia’s monsoon climates, Southeast Asia’s tropical conditions, the arid Middle East, Europe’s precision instrumentation, and the automotive and aerospace sectors of the Americas. With a near‑zero thermal expansion coefficient and a Curie temperature above 230 °C, the 1J36 strip maintains tight dimensional tolerances across a broad temperature range, making it ideal for precision transformers, sensors, magnetic shielding, and compensation coils. Drawing upon decades of material‑science expertise, this alloy strip offers tensile strength exceeding 490 MPa and yield strength above 275 MPa, combined with elongation over 40%, ensuring mechanical integrity during forming and assembly. Tailored to standards such as GB/T 15018‑1994 and ASTM B388, it meets the rigorous demands of advanced control systems and high‑performance electronic assemblies.
