Description:

K-740, also a soft PZT, is excellent for applications such as 1-3 composites, multi-element arrays, and actuators. Particularly in the medical industry, K-740 is a reliable second source to the CTS 3203HD ceramic. Its less porous, more uniform fine grain structure are a new standard where element to element consistency is necessary.
