Product Introduction

Our 1J85 Soft Magnetic Plate is a high-performance iron-nickel alloy tailored for precision sensors and high-frequency applications. With approximately 85% nickel, balanced with iron and trace elements, this alloy delivers exceptional magnetic permeability (up to 0.15 H/m) and ultra-low coercivity (0.02 Oe). Its high nickel content ensures outstanding sensitivity and low core losses, making it perfect for precision sensors, transformers, and magnetic shielding in demanding industries like electronics and aerospace.

The soft magnetic materials market is booming, driven by the rise of precision electronics, 5G technology, and aerospace advancements. As industries demand higher sensitivity and compact designs, alloys like 1J85 are critical for their low-loss and high-permeability properties. Market projections show strong growth through 2030, with electronics, aerospace, and telecom sectors leading the way. We tackle challenges like material precision with advanced vacuum melting and controlled annealing, delivering plates that meet the strictest industry standards.
