High Purity Aluminum Oxide Metallized Ceramic Insulator
Normally. the ceramic components in gas discharge tube (GDT) is made from high purity aluminum oxide, also called Alumina Ceramic. The metallized ceraemic insulator work as a key part in Ceramic to metal seal for vacuum hermeticity because of thier outstanding electrical insulation strength and excellent leakage rate after brazing. There are many different design to meet different GDT device, to meet different GDT application. In order to meet customers requirement with our mold design capability, it helps us to achieve complicated figure of metallized ceramic insulator.
We offer a selection of types of metallization to meet different application from different customers, the main metallization type included as following:
1. Raw ceramic body + Mo/Mn metallization................2. Raw ceramic body + Mo/Mn ( W) metallization + nickle plating
3. Raw ceramic body + W metallization + gold plating..............................................4. Raw ceramic body + silver plating
We are capable to supply a diversity of Metallized ceramics part from general tolerance to high precision ones via fine grinding, CNC machining etc. secondary processes. Also we can provide prototyping service with a very small quantity batch.
