China Manufacturer Industrial Aluminum Oxide Metalized Ceramic Isolator
The description of the metalized ceramics
In the ceramic-to-metal joining technology, a certain metallic layer on the ceramic surface is needed, like Molybdenum or Tungsten, then it could achieve the connection of metal and ceramic by means of high-temperature brazing. Metalized alumina Ceramic Parts are commonly used in many applications, like electronics, High-Vacuum Technology, Medical Technology, and Sensor Technology.
The metalized alumina ceramic parts we manufactured are famous for the excellent bonding strength, super mechanical, excellent electrical insulation, exceptional thermal features.
Standard types of metalization
1. Alumina ceramic base + silver (Ag) plating directly
2. Alumina ceramic base + molybdenum (Mo/Mn) metallization
3.Alumina ceramic base + molybdenum (Mo/Mn) metallization + nickel (Ni) plating
4. Alumina ceramic base + tungsten (W) metalization + gold (Au) plating

The prime features of alumina metalized ceramics
1. High bonding/brazing strength with ideal vacuum tightness between the assembly
2. With diamond-like hardness of 85 HRV and superb compressive strength
3. Great insulation strength and volume resistivity that is suitable for various high-voltage, high-current applications
4. Chemical stability, anti-aging, even if it works in a variety of harsh environments, is free of rust forever.
5. Over 276 times wear resistance in comparison with stainless steel, which leads to a long service lifespan.
The typical application of metalized ceramics
Remark:
Metalized ceramics are widely used in electronics, high-vacuum technology, sensors, and medical fields,
like vacuum interrupters, electron tubes, feed-throughs, medical linear accelerators/ power tubes, photomultipliers,
X-ray tubes, and pressure sensors
