Product Description

Ceramic Metallized Cylinder for Traveling Wave Tubes

The ceramic metallized cylinder is made of alumina oxides with min. 95% purity. It can be shaped via hot pressing, ISO pressing. To meet their special usage, a metal coating on certain surface is to be plated via banding, screen printing, brushing, spraying, like Mo/Mn with nickle plating.

The ceramic metal cylinder have a very good bonding strength with ideal air tightness at ceramic to metal jointing technology.
