Background information about piezo cylinders

Custom Designed and Engineered Cylinders
To meet your unique specifications, APCI can manufacture cylinders (tubes) in a wide range of sizes and thicknesses and out of materials other than our standard material (APC 850-E). To discuss your requirements, simply contact an APCI representative with your drawing or sketch including: tolerance values, material, and electrode pattern.

Standard Piezo Cylinders
Constructed from APC 850-E material (See properties below).
Electrodes on inside surface and outside surface, cylinders poled through the electrodes. Please inquire about other poling options.
