Additional information

Large Size Metallized Ceramic Ring

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.
