1J22 Soft Magnetic Alloy Strip : Ultra‑High Saturation and Precision Performance

Product Description 

1J22 Soft Magnetic Alloy Strip represents the pinnacle of high‑saturation iron‑cobalt‑vanadium alloys, engineered to deliver exceptional magnetic performance . Boasting a saturation flux density of up to 2.4 Tesla and a Curie temperature of 980 °C, this strip ensures stable operation under extreme conditions —from Southeast Asia’s tropical humidity and the Middle East’s desert heat to Europe’s precision instrumentation environments and the Americas’ power grids . Its elevated magnetostriction coefficient (60 – 100 ×10⁻⁶) enables high‑output magnetostrictive transducers , while low electrical resistivity (0.40 μΩ·m) minimizes eddy‑current losses in sensitive cores . The balanced composition of 49 – 51 % cobalt and 0.80 – 1.80 % vanadium, with trace carbon, manganese, silicon, phosphorus, sulfur, copper, and nickel, provides tensile strength of 490 MPa in the annealed state and 1,325 MPa when unannealed, facilitating precision stamping and intricate geometries . Fully compliant with GB/T15002‑1994, 1J22 Soft Magnetic Alloy Strip empowers engineers in telecom, automotive, aerospace, and energy sectors to reduce component size and enhance efficiency .
