Product Introduction

Our 1J85 Alloy Plate is a high-performance iron-nickel alloy engineered for advanced magnetic shielding and high-frequency applications. With approximately 85% nickel, balanced with iron and trace elements, this alloy offers exceptional magnetic permeability (up to 0.15 H/m) and ultra-low coercivity (0.02 Oe). It’s the go-to choice for shielding sensitive electronics, high-frequency transformers, and inductors, delivering reliable performance in demanding environments like telecom and medical systems.

The soft magnetic materials market is on fire, driven by the rapid growth of telecommunications, 5G infrastructure, and medical electronics. As devices get smaller and more sensitive to electromagnetic interference, alloys like 1J85 are in high demand for their low coercivity and shielding capabilities. Market trends project strong growth through 2030, with telecom, electronics, and renewable energy sectors leading the charge. We tackle challenges like precision processing with advanced vacuum melting and controlled annealing, ensuring our plates meet the highest industry standards.
