Product Description
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 in 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, Sensor Technology.
The metalized alumina ceramic parts we manufactured are famous for their excellent bonding strength, super mechanical properties, excellent electrical insulation, and exceptional thermal features.
The prime features of alumina metalized ceramics
2. With diamond-like hardness to be 85 HRV and superb compressive strength
3. Great insulation strength and volume resistivity that fit for various high voltage high current applications
4. Chemical stability, anti-aging even if it works in a variety of harsh environments, free of rust forever.
5. Over 276 times wear resistance in comparison with stainless steel, leads to a long service lifespan.
The key parameters of capability
