High Purity Alumina Metallized Ceramic Tubing

High Purity Alumina Metallized Ceramic Tubing

We take use of advanced technology to provide industry extensive Metallized ceramics, it covers a selection of raw materials to be the base of Metallized Ceramic Components, for example aluminum oxide, zirconium oxide, beryllia, nitride aluminum. These metallized ceramic parts are used in critical assemblies brazed in high vacuum technology, medical technology, sensor technology, military and aerospace.

We are able to manufacture a diversity of different specification Metallized Ceramic Tube from different design to different dimensions. Very 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 included as below:

1. Raw ceramic + Molybdenum/Manganese (Mo/Mn) , or Tungsten (W) metallization

2. Raw ceramic + Mo/Mn metallization + Nickle plating 3.Raw ceramic + W metallization + Nickle plating 4.Raw ceramic + W metallization + Gold plating

We are capable of achieve different grade precision level via fine grinding, CNC machining, cutting processes. 

The finest tolerance can be +/-0.01 for overall dimensions.  Also glazing treatment on internal, or external surface can be done by ourselves.

Features of Metalized Ceramics

● High bonding / brazing strength ● Low leakage rate ● High Insulation strength ● High mechanical strength 

● Low thermal expansion ● Resistant to corrosion free of rust ● Min. electric resistance and vacuum tightness

Application of metalized ceramic tube

Widely used in vacuum interrupters, Electron tubes,Gas discharge tube, Vacuum capacitor,Vacuum thyristors, Surge arresters,Thyristor housings,Diode housings,Power grid tubes,Traveling wave tubes,Insulator rings and cylinder,X-ray tubes and so on.

Main Manufacturing Flow Chat

We have a complete comprehensive of production equipment for Metallized Ceramics from shaping to electroplating.

It helps us to make the dimensional consistency very well. Also, helping us to offer a competitive price.
