Glazed Alumina Metallized Ceramic Tube For Vacuum Interrupters

This metallized ceramic cylinder is commonly used in vacuum switch, vacuum interrupter, vacuum breaker. It is made of min. 95% alumina via dry pressing, or hot pressing. We are able to manufacture a diversity of different specification metallized ceramic cylinders, including different dimensions, different type, different metal coating on surface.

Small part-size to large part-size is availability, the min. diameter can be 1 mm, the largest diameter is up to 800 mm.The typical plating as below:

1. Raw ceramic + Mo/Mn metallization 2. Raw ceramic + Ag coating 3. Raw ceramic + W metallization + Au coating

4. Raw ceramic + Mo/Mn metallization + Nickle coating

We are capable of offering high precision metallized ceramic tube via variety of grinding, CNC machining, cutting processes. The finest tolerance can be +/-0.001 for length, +/-0.0051 for inner and outer diameter.
