1J38 Soft Magnetic Alloy Strip: Low Coercivity, High Magnetic Permeability, and High Saturation Magnetic Induction, Exhibiting Stable Magnetic Performance over the –40 °C To 60 °C Temperature Range
1J38 Soft Magnetic Alloy Strip is an advanced nickel‑iron‑chromium precision strip engineered for temperature‑compensated electromagnetic components. With 38 wt % nickel and 13 wt % chromium, this strip delivers high initial permeability, low hysteresis loss, and a tailored Curie temperature for compensation applications. Its near‑zero thermal expansion ensures dimensional integrity from –50 °C to +150 °C—ideal for South Asia’s humid climates, Southeast Asia’s tropical environments, the arid Middle East, Europe’s precision instrumentation, and North/South America’s automotive and aerospace control systems. Engineered via cold‑rolled processing, the 1J38 strip offers tensile strength up to 600 MPa, yield strength around 450 MPa, and elongation above 25%, supporting fine stamping and winding. Exceptional corrosion resistance in moisture, saline, and hydrazine media preserves magnetic performance in harsh environments. Conforming to GB/T 15005‑1994 and GB/T 15018‑1994 standards, this strip delivers consistent magnetic and mechanical properties. Additionally, its optimized electrical resistivity of 0.44 Ω·mm²/m and thermal conductivity of ~44 W/m·°C reduce eddy‑current losses and facilitate thermal management in high‑frequency transformers and inductors.
