The Prime Characteristics

1. High bonding/brazing strength with ideal vacuum tightness between the assembly

2. Great insulation strength and volume resistivity that fit various high voltage high current applications     

3. Chemical stability, anti-aging even if it works in various harsh environments, free of rust forever.

4. Over 276 times wear resistance compared to stainless steel leads to a long service lifespan.

 

Typical Applications

Metalized ceramics are widely used in electronics, high-vacuum technology, sensors, and medical fields, like vacuum interrupters, electron tubes, feed-throughs, medical linear accelerators/ power tubes, photomultipliers, X-ray tubes, and pressure sensors.

 

Product Description

In the ceramic-to-metal joining technology, a certain metallic layer on the ceramic surface is needed, like Molybdenum or Tungsten, then it could be achieved in connection of metal and ceramic using high-temperature brazing. Metalized alumina Ceramic Parts are commonly used in many applications, like electronics, High-Vacuum Technology, Medical Technology, and Sensor Technology.

Our metalized alumina ceramic parts are famous for their excellent bonding strength, super mechanical, excellent electrical insulation, and exceptional thermal features. 
 

 

Standard types of metalization
1. Alumina ceramic base +  silver (Ag) plating directly                            2. Alumina ceramic base +  molybdenum (Mo/Mn) metallization
3.Alumina ceramic base +  molybdenum (Mo/Mn)  + nickel (Ni) plating  4. Alumina ceramic base + tungsten (W) metalization + gold (Au) plating
