The prime features of alumina metalized ceramics
1. High bonding/brazing strength with ideal vacuum tightness between the assembly
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, it leads to a long service lifespan.

The description of the metalized ceramics
We manufacture a diversity of metalized ceramics with different specifications, like metallized ceramic tubes, metallized ceramic rings, metallized ceramic substrates, 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 ceramics 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.

The typical application of metalized ceramics
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
