Ceramic to Metal Feedthrough

High Voltage High Vacuum Ceramic to Metal Hermetic Feedthough 

3X Ceramic Parts company specialized in developing and  producing  ceramic to metal hermetic feedthough that are used in the high operating temperature , high vacuum and harsh condition . It could meet customer the requirements of air tight seal , high working temperature resistance ,  electrical insualting , and some times under high pressure .  Air tight  hermetic seal protect from liquid , pressure ,  moisture, gas,  vacuum, corrosion resistance temperature.

We normally choose 95% (96%) alumina ceramic material as the insulator .  For the conductor , sometimes we  use Kovar and Copper Cored Kovar,  sometimes we use Stainless steel  or copper .  While we use Titanium or Cu ,  Cu alloy , NiFe Alloys & NiFeCO (Kovar)  as housing .
