According to our (Global Info Research) latest study, the global Extremely Thin Permalloy Foil market size was valued at US$ 94.66 million in 2025 and is forecast to a readjusted size of US$ 148 million by 2032 with a CAGR of 6.5% during review period.
In 2025, global Extremely Thin Permalloy Foil production reached approximately 400 tons, with an average global market price of around 230 US$/kg.
Extremely Thin Permalloy Foil refers to a high-permeability soft magnetic nickel–iron alloy foil, typically based on Ni-Fe or Ni-Fe-Mo compositions such as 1J79, 1J85, 79HM, moly permalloy, PB/PC/PD/PE series permalloys, and related high-nickel magnetic alloys. Based on the product ranges of the confirmed manufacturers, the statistical thickness scope can be defined as approximately 2–100 μm, with 2–10 μm representing ultra-high-precision specialty foil, >10–50 μm representing mainstream extremely thin magnetic shielding and sensor-use foil, and >50–100 μm representing thin permalloy foil or precision soft magnetic strip used in shielding, yokes, magnetic sensors, relays, transformers, inductors, magnetic heads, aerospace electronics, medical electronics, and precision instruments. The product is manufactured through vacuum melting, precision cold rolling, repeated annealing, magnetic heat treatment, surface cleaning, slitting, and tight tolerance control, and is characterized by very high magnetic permeability, low coercivity, low magnetic loss, good weak-field sensitivity, excellent shielding performance, and stable magnetic properties in compact electronic or precision magnetic assemblies.
The average single-line production capacity of Extremely Thin Permalloy Foil is 40 tons, the average gross profit margin was 31.8%.
The upstream includes high-purity nickel, iron, molybdenum, copper and other alloying metals, as well as vacuum melting materials, protective gases, rolling lubricants and annealing atmospheres. The midstream covers alloy smelting, casting, forging, hot rolling, cold rolling, precision foil rolling, heat treatment, magnetic annealing, surface cleaning, slitting and quality testing. The downstream includes magnetic shielding components, precision sensors, transformers, inductors, relays, medical electronics, aerospace systems, communication equipment, industrial instruments and consumer electronic modules.
The cost structure is dominated by nickel and alloy metals, accounting for about 45%–60%, followed by precision rolling, annealing and magnetic property control at 18%–25%, labor and manufacturing overhead at 8%–12%, energy and protective atmosphere costs at 5%–8%, quality inspection, slitting and packaging at 4%–7%, and R&D, certification, sales and administration at 6%–10%. Ultra-thin grades have higher yield-loss and process-control costs due to strict thickness tolerance and magnetic performance requirements.
Demand is driven by miniaturized electronics, high-sensitivity sensors, electromagnetic shielding, aerospace electronics, medical equipment, industrial automation and high-frequency precision magnetic components. Business opportunities are concentrated in ultra-thin magnetic shielding foils, customized slitting materials, high-permeability sensor foils, low-coercivity precision alloys, medical and aerospace-certified materials, and localized supply replacement. Growth is supported by increasing requirements for compact magnetic components, but barriers include nickel price volatility, strict heat-treatment control, thickness uniformity, magnetic consistency and long customer qualification cycles.
