Products

InSealing produces metalized ceramic, and ceramic feedthrough used in military, aerospace, medical, and high-reliability industrial applications. Ceramics are extremely reliable in high vacuum applications and compatible with metals such as Titanium, AlSi, Kovar, Ally42, CuMo, and CuW.

Metallized ceramics, Ceramic feed-throughs can support high-frequency applications up to 30GHz and offer a coplanar surface for wire bonding.

Ceramic Material is 96% Alumina
