We supply products made from the following piezoelectric ceramic formulations:

Navy Type I, Navy Type II, Navy Type III, Navy Type V, Navy VI and PKI 700

• Navy Type I (PKI-402, PKI-406 and PKI-409):
  Denoted as Navy Type I, it is designed to serve as a driver where high power and low losses are dictated by design. It is primarily well suited for ultrasonic cleaners and sonars. PKI 406 is suitable for medical applications.

• Navy Type II (PKI-502 and PKI-506):
  Denoted as Navy Type II, it is designed for applications that require high electromechanical activity and high dielectric constant. These are used primarily as recievors e.g. hydrophones, phono pickups, sound detectors, accelerometers, delay lines, flow detectors and flow meters.
• Navy Type III (PKI-802 and PKI-804):
  Denoted as Navy Type III, it is specifically used as a driver that exhibits low losses under extreme driving conditions and has a high Q. PKI 804 is well suited for medical applications.

• Navy Type V (PKI-532):
  Denoted as Navy Type V, this ceramic is used as sensors that require low impedance, high dielectric constant and high sensitivity.

• Navy Type VI (PKI-552 and PKI-556):
  Denoted as Navy Type VI, this ceramic is used as sensors that require extremely high dielectric constant and large displacements. PKI 556 material has been slightly modified to give a higher g₃₃ value, higher k₃₃ , and lower loss factor. This formulation aids the design engineer by giving more flexibility within the type VI class of materials

• PKI 700:
  This material has low dielectric constant, high Q_M, high shear coupling coefficient, good temperature stability and low aging characteristics. Common use of this material is in delay lines and accelerometers.
