Piezoelectric Staves

CeramTec is a leader in the design and manufacture of complex piezoelectric ceramic components and assemblies used in a wide range of applications and cutting edge technologies.

Applications include
    • Choice of metallisation (Silver, Nickel, Gold and others)
    • Evaporated and chemically deposited metallisation's available
    • Thickness/Radial frequency tuning available on request
    • Wrap around electrode configuration
    • Wide choice of piezoceramic formulations
    Typical Stave Configurations
    Piezoelectric tube segment in grey and yellow


    Piezoelectric stave in grey and yellow


    Other custom stave design in combination with electrode configurations and metallisation’s are available on request.

    Dimensional Range

    Barrel Design

    • Outside Diameter from 8mm (0.3”) to 150mm (5.9”)
    • Inside Diameter from 6mm (0.24”) to 140mm (5.5”)
    • Length from 1mm (0.039”) to 150mm (5.9”)

    Stave Design

    • Length from 1mm (0.039”) to 150 (5.9”)
    • Width from 8mm (0.3”) to 25.4mm (1”)
    • Thickness from 5mm (0.2”) to 25.4mm (1”)

    Custom sizes dimensions outside of the above may be possible – please consult for further information.

    Standard Mechanical Tolerances
    • Outside Diameter (*) ± 0.150mm
    • Inside Diameter (*) ± 0.150mm
    • Length (**) ± 0.05mm
    • Width (**) ± 0.150mm
    • Thickness (**) ± 0.05mm
    • Angle ± 0.25°

    Tighter mechanical tolerances are achievable but are dependent on the ring inside and outside diameters and thickness.

    Notes: (*) Barrel design, (**) Wedge design

    Metallisation Type
    • Silver fired thick film - Evaporated Nickel
    • Electroless nickel - Gold flash
    • Tin - Evaporated Gold and others available on request
