Soft PZT

Pz27 is a solid, all-round material with good coupling factors and piezoelectric charge coefficients. Capable of serving as a direct replacement for all other Navy II materials, it has greatly improved aging rates and shows very stable performance over time. It is characterized by a low mechanical quality factor and low temperature coefficients.
