HIGH POWER FERRO ELECTRICALLY-HARD MATERIALS

SP-4 AND SP-8 GRADES

These grades of materials based on Lead Zirwnate Titanate can withstand high level of electrical excitation and mechanical stresses. These are admirably suited for high voltage or high power generators and transducers.

1SP-4

SP-4 is well suited for all high powered transducers for ultrasonic cleaning and deep water hydrophones, liquid atomisation and other high power acoustic radiation applications. It is a modified version of Lead Zirconate Titanate material capable of producing large mechanical drive amplitudes while maintaining low dielectric and mechanical losses.

Acoustic Power : About 7 - 10 W/cm²
Working Temp. : 90º C max.

SP-8

SP-8 is designed for high surface loading power transducers for plastic welding and material processing. It has an excellent mechanical quality factor, reasonably good coupling coefficient and low dielectric loss factor which provide ultimate power handling capability.

Acoustic Power : About 10 - 15 W/cm²
Working Temp. : 95º C max.
