PiezoNova offers high-quality piezo elements based on PZT (Lead Zirconate Titanate)
We offer piezoceramics of various dimensions and shapes (disc, plate, ring or hemisphere).
We standartly use to Silver or Gold for metallisation of electrode.
We can provide all ceramics also with wrap-around electrode (WAE).
If you do not choose from standard offer, please contact us at info@piezonova.com
