Product Description

Metallized Ceramic Insulators for High Voltage Feedthru

We manufacture a diversity of metallized ceramic insulators with different specification, like Metallized Ceramic Tube, Metallized Ceramic Ring, Metallized Ceramic Substrate and so on. These Metallized Ceramics are made of aluminum oxide, zirconium oxide or beryllia ceramics via dry pressing, injection molding, or hot pressing.

We can proceed with small part-size to large part-size, the min. diameter can be 1mm, the largest diameter is up to 800mm. In order to meet customers' different needs, we offer a selection of types of metallization, the typical ones as below:

1. Ceramic base + Molybdenum (Mo/Mn) metallization ...................................2. Ceramic base + Mo/Mn metallization + Nickle(Ni) plating

3. Ceramic base + Silver(Ag) plating...........................................................................4. Ceramic base + Tungsten (W) metallization + Gold(Au) plating

We offer different grade precision Metallized Ceramic Insulator when you need these ceramic components to be very precise, these vacuum ceramic components would be further proceeded via lapping, grinding, CNC machining before metallization on site production. The finest tolerance can be +/-0.001 for length, +/-0.005 for both inner and outer diameter.
