Product Description

 

Ceramic-to-Metal is an ideal solution for brazing ceramic to metal parts that are not able to directly bond with ceramic.Innovacera

is experienced in providing technical solutions on ceramic-to-metal for engineering components.The high-pressure laser ceramic

electrode, which is the key component to connect the internal vacuum chamber with the external parts. The material requires

vacuum sealing and excellent insulation. The main components are vacuum sealing flange, ceramic or glass insulator, oxygen-free

copper conductive rod piece, etc., it provides reliable sealing performance and excellent insulation performance at high-pressure

conditions. it's commonly used in CO2 laser equipment.

 

FEATURES

1.The ceramic material is with even texture, each batch has stability quality and flexural strength.
2.Metal layer is dense, constant,smooth and good weldability.

3.Excellent electrical insulation,low dielectric constant, good abrasion, and corrosion resistance.
4.High tensile strength, good airtightness to meet the requirement of the high-frequency, high-power and safe electrical components

APPLICATIONS

1.High voltage feedthrough for X-ray quipment
