One common method of connecting alumina ceramic tubes is through welding copper fittings to the ends of the tubes. This process requires precision and skill to ensure a strong and leak-proof connection. The copper fittings provide a reliable connection that can withstand high temperatures and vacuum pressures.
The combination of alumina ceramic and copper welding creates a durable and long-lasting tube that is suitable for demanding applications. The copper fittings also provide a good thermal conductivity, which helps to maintain uniform heat distribution throughout the tube.
vacuum alumina ceramic tubes welded with copper fittings are a reliable and effective solution for high temperature and vacuum environments. Their durability and resistance to thermal and chemical stresses make them an ideal choice for various industrial applications.

Feedthroughs (or vacuum feedthroughs) come in many forms to transfer electrical currents, signals, fluids, gases or mechanical movements from outside the vacuum (air side) to the inside (vacuum side) of a vacuum chamber to equipment within the chamber. The entry point for the feedthrough must be vacuum-sealed via a suitable through hole. The feedthrough can be weldable (weld-on) or connected with a CF, KF or ISO vacuum flange to the vacuum chamber.

Our metallizing processes could be customized according to clients’ requirements.

The vacuum electrode flange is usually composed of the following structures:
1. Contact: used to connect two flanges, usually made of copper or stainless steel.
2. Flange: a flat plate mounted on the contact, between which a vacuum sealing chamber is formed.
3. Bolts: Components for fixing and connecting flanges.
4, insulation gasket: the insulation material installed between the bolt and the flange to ensure the insulation performance of the flange.
5, conductive plug: used for grounding at non-standard connections to ensure the electrical safety of the system.
