Global Permalloy Industry Outlook 2026-2032: Analyzing the Background of Increasing Demand and a Growth Rate of 2.8%
Permalloy is a soft magnetic alloy with high permeability, primarily composed of nickel and iron. Typical compositions include Ni-Fe systems with a nickel content of about 35-50% and high-nickel systems with about 77-82%. Ni-Fe-Mo and Ni-Fe-Cu systems, which have added molybdenum or copper, are also used. Due to its high initial permeability, low coercivity, low hysteresis loss, and low magnetostriction, it is suitable for applications that require responsiveness to weak magnetic fields and magnetic shielding performance. According to the latest research report published by Global Reports titled "Global Market Size, Share, Company Rankings, Sales, and Demand Trends Forecast for Permalloy (2026-2032)," the global market for permalloy is expected to expand from approximately \$279 million in 2025 to about \$283 million in 2026, with a projected compound annual growth rate (CAGR) of 2.8% from 2026 to 2032, reaching approximately \$334 million by 2032. As the stability of magnetic properties is emphasized in precision electronic devices, industrial sensors, and medical/aerospace equipment, the demand for permalloy as a soft magnetic material with high permeability and low coercivity remains robust.

basic information
High sensitivity and electromagnetic environment measures support demand. The main applications of permalloy include magnetic shields, instrument transformers, current sensors, relays, small transformers, low-noise inductors, and magnetic heads. As electronic devices become smaller and more sensitive, the demand for materials that can accurately detect weak magnetic signals and suppress errors caused by external magnetic fields is increasing. In leakage circuit breakers, current detection components, and precision relays, variations in magnetic properties affect detection accuracy and operational stability, making the alloy composition and heat treatment management tailored to specific applications crucial. Additionally, in electric vehicles (EVs), industrial control devices, communication equipment, and semiconductor manufacturing equipment, the importance of current sensing and electromagnetic compatibility (EMC) is growing. In medical imaging diagnostic devices, aerospace equipment, and scientific research instruments, shielding from external magnetic fields and stable magnetic performance are required, supporting the adoption of high-performance permalloy.

Applications/Examples of results
Alloy composition and processing technology determine product competitiveness. In the manufacturing of permalloy, raw materials such as nickel, iron, molybdenum, and copper are procured, and through processes including vacuum melting, forging, hot rolling, cold rolling, wire drawing, annealing, slitting, punching, and inspection, products are created. The product forms vary widely, including strips, thin strips, sheets, foils, wires, rods, and powders. In particular, magnetic properties are influenced not only by composition and impurities but also by internal stresses generated during processing and annealing conditions. There are cases where permeability decreases due to punching, bending, welding, and assembly, making it essential to design processes that stabilize magnetic properties after processing.
