Product Introduction

Our 1J75 Nickel-Iron Plate is a high-performance Soft Magnetic Alloy tailored for high-frequency inductor cores and other precision applications. With approximately 75% nickel, balanced with iron and minor additives, this alloy delivers exceptional magnetic permeability (up to 0.1 H/m) and ultra-low core losses. It’s a reliable choice for compact, high-efficiency components like inductors, transformers, and magnetic shields, ensuring top-notch performance in demanding high-frequency environments.

The soft magnetic materials market is growing fast, driven by the boom in high-frequency electronics, telecommunications, and renewable energy systems. As devices trend toward smaller sizes and higher efficiency, alloys like 1J75 are in high demand for their ability to minimize energy loss in high-frequency applications. Market projections show robust growth through 2030, with electronics, telecom, and automotive sectors leading the charge. We tackle challenges like processing precision with advanced vacuum melting and controlled annealing, ensuring our plates meet the highest standards for performance and reliability.
