Product Introduction

Our 1J75 Soft Magnetic Bar is a high-performance iron-nickel alloy designed for high-temperature magnetic components. With approximately 75% nickel, balanced with iron and trace elements, this alloy delivers exceptional magnetic permeability (up to 0.1 H/m) and low coercivity (0.05 Oe), maintaining stability in extreme heat. It’s the perfect choice for transformers, sensors, and magnetic shielding in demanding environments like aerospace and industrial systems.
