    The magic touch

    Haptic actuation devices are powerful sensory tools that drive advancements in augmented and virtual reality applications. Our Hiperco® alloys improve user experience across the board:

    • 40% higher induction and industry-leading high permeability
    • 15% faster device acceleration
    • Better touch response and sensory feedback
    • Significant power savings
    • Longer battery and device life
    • Product miniaturization

    Our corrosion-resistant Chrome Core® alloys offer an alternative for high reliability in more demanding ambient operating environments.

    Our Evanohm® R resistance alloys have low TCR and are highly stable, well-suited for accurate readings during charging and operating cycles in battery management systems.

    Our soft magnetic alloys have also been used for magnetic shielding and flux focusing to resolve magnetic interference issues inherent in some highly compact designs.

    Higher sound pressure levels for improved audio output

    Microspeakers

    Big advances in small electronics

    The ever-expanding demand for miniaturized electronics and multimedia technology requires smaller microspeakers with improved audio output. Reducing the size of magnetic circuits has been an obstacle in the past — but no more.

    Our materials and processes allow OEMs to produce smaller, lighter acoustic transducers with similar power levels, or create more powerful transducers of a similar size.

    Microspeakers built with Hiperco® soft magnetic alloys have the competitive advantage over steel-based magnetic assemblies:

    • More sound pressure level (SPL) dense
    • 30% smaller, lighter soft magnet
    • 17% smaller, lighter rare earth permanent magnet
    • 7% more battery life due to reduced operating current

    Compact, lightweight sound amplification

    Hearing Aids

    An audio lifeline

    Hearing aids have to perform with varying and unpredictable audio inputs while providing exceptional sound amplification and clarity. Devices must also be compact and lightweight for user experience and use compliance.

    To meet these needs, hearing aid acoustic designers rely on very high-permeability soft magnetic alloys in their dynamic drivers.

    Our high-permeability iron-nickel alloys offer different combinations of properties suited for components in high-fidelity systems.

    High Permeability 49 has good magnetic induction and provides excellent response and miniaturization. HyMu 80 has exceptional permeability and is ideal for magnetic shielding to insulate and isolate critical components.
