Product Description

What is metallized ceramics?

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 achieve in connection of metal and ceramic by means of high-temperature brazing. Metalized alumina Ceramic Parts are commonly used in many applications, like electronics, High-Vacuum Technology, Medical Technology, and Sensor Technology.

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

Standard types of the 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
