High Precision Customized Metallized Ceramic Insulator
Metallized ceramic insulator plays a very important role in many different vacuum devices because of their remarkable electrical, mechanical and thermal properties. We are able to produce a variety of customized vacuum ceramic components according to customers' drawing or specification, like metallized ceramic tube, metallized ceramic substrate, metallized ceramic discs, metallized ceramic ring and so on.
We offer a selection of types of metallization to meet different needs from different customers, the main metallization types included as following:
1. Raw ceramic body + silver plating.............................................................................2. Raw ceramic body + copper plating
3. Raw ceramic body + Tin Plating................................................................................4. Raw ceramic body + Mo/Mn metallization
5. Raw ceramic body + Mo/Mn ( W) metallization + nickel plating................................6. Raw ceramic body + W metallization + gold plating
We are capable to supply a diversity of metallized ceramic part from general tolerance to high precision ones via fine grinding, CNC machining, etc. secondary processes. Also, we can provide a prototyping service with a very small quantity batch.
