High Purity Alumina Vacuum Ceramic Tube with Metallization

All our Metallized ceramics offer exceptional metallized-seal strength and hermeticity which can be welded with a selection of metal components, including Kovar, Copper, Stainless steel and so on.

We could provide a selection of metallization types with in-house complete manufacturing equipment,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, +/-0.01 for inner and outer diameter.

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 + Mo/Mn metallization + Nickle plating

Technical Key Parameters of vacuum ceramic tube
