Cell Lab Nickel/Iron (Ni/Fe 81/19 wt.%) Pellets Evaporation Materials

Soft Magnetic Alloy for Thin-Film and Microelectronic Applications

General Description

Cell Lab Nickel/Iron (Ni/Fe 81/19 wt.%) Pellets are precision-engineered alloy evaporation materials designed for magnetic thin films, microelectronic components, and sensor applications. The Ni–Fe system—often referred to as Permalloy—is valued for its low thermal expansion, excellent soft magnetic behaviour, and corrosion resistance, making it a cornerstone material for flux guides, magneto-resistive sensors, and bubble memory devices.

These pellets provide high stability during E-beam and thermal evaporation, ensuring consistent thin-film composition and uniformity across substrates.
